2.0 CPU ARCHITECTURE OVERVIEW
* Linear indirect access of 32K word pages within program space is also possible using any working register, via table read and write instructions. Table read and write instructions can be used to access all 24 bits of an instruction word. Overhead-free circular buffers (modulo addressing) are supported in both X and Y address spaces. This is primarily intended to remove the loop overhead for DSP algorithms. The X AGU also supports bit-reversed addressing on destination effective addresses, to greatly simplify input or output data reordering for radix-2 FFT algorithms. Refer to Section 4.0 for details on modulo and bit-reversed addressing. The core supports Inherent (no operand), Relative, Literal, Memory Direct, Register Direct, Register Indirect, Register Offset and Literal Offset Addressing modes. Instructions are associated with predefined Addressing modes, depending upon their functional requirements. For most instructions, the core is capable of executing a data (or program data) memory read, a working register (data) read, a data memory write and a program (instruction) memory read per instruction cycle. As a result, 3-operand instructions are supported, allowing C = A+B operations to be executed in a single cycle. A DSP engine has been included to significantly enhance the core arithmetic capability and throughput. It features a high speed 17-bit by 17-bit multiplier, a 40-bit ALU, two 40-bit saturating accumulators and a 40-bit bi-directional barrel shifter. Data in the accumulator or any working register can be shifted up to 16 bits right or 16 bits left in a single cycle. The DSP instructions operate seamlessly with all other instructions and have been designed for optimal real-time performance. The MAC class of instructions can concurrently fetch two data operands from memory, while multiplying two W registers. To enable this concurrent fetching of data operands, the data space has been split for these instructions and linear for all others. This has been achieved in a transparent and flexible manner, by dedicating certain working registers to each address space for the MAC class of instructions. The core does not support a multi-stage instruction pipeline. However, a single stage instruction pre-fetch mechanism is used, which accesses and partially decodes instructions a cycle ahead of execution, in order to maximize available execution time. Most instructions execute in a single cycle, with certain exceptions. The core features a vectored exception processing structure for traps and interrupts, with 62 independent vectors. The exceptions consist of up to 8 traps (of which 4 are reserved) and 54 interrupts. Each interrupt is prioritized based on a user assigned priority between 1 and 7 (1 being the lowest priority and 7 being the highest) in conjunction with a predetermined `natural order'. Traps have fixed priorities, ranging from 8 to 15.

2.1
Core Overview
The core has a 24-bit instruction word. The Program Counter (PC) is 23 bits wide with the Least Significant (LS) bit always clear (see Section 3.1), and the Most Significant (MS) bit is ignored during normal program execution, except for certain specialized instructions. Thus, the PC can address up to 4M instruction words of user program space. An instruction pre-fetch mechanism is used to help maintain throughput. Program loop constructs, free from loop count management overhead, are supported using the DO and REPEAT instructions, both of which are interruptible at any point. The working register array consists of 16x16-bit registers, each of which can act as data, address or offset registers. One working register (W15) operates as a software stack pointer for interrupts and calls. The data space is 64 Kbytes (32K words) and is split into two blocks, referred to as X and Y data memory. Each block has its own independent Address Generation Unit (AGU). Most instructions operate solely through the X memory AGU, which provides the appearance of a single unified data space. The Multiply-Accumulate (MAC) class of dual source DSP instructions operate through both the X and Y AGUs, splitting the data address space into two parts (see Section 3.2). The X and Y data space boundary is device specific and cannot be altered by the user. Each data word consists of 2 bytes, and most instructions can address data either as words or bytes. There are two methods of accessing data stored in program memory: * The upper 32 Kbytes of data space memory can be mapped into the lower half (user space) of program space at any 16K program word boundary, defined by the 8-bit Program Space Visibility Page (PSVPAG) register. This lets any instruction access program space as if it were data space, with a limitation that the access requires an additional cycle. Moreover, only the lower 16 bits of each instruction word can be accessed using this method.

2.2 Programmer's Model
2.2.1
The programmer's model is shown in Figure 2-1 and consists of 16x16-bit working registers (W0 through W15), 2x40-bit accumulators (AccA and AccB), STATUS register (SR), Data Table Page register (TBLPAG), Program Space Visibility Page register (PSVPAG), DO and REPEAT registers (DOSTART, DOEND, DCOUNT and RCOUNT), and Program Counter (PC). The working registers can act as data, address or offset registers. All registers are memory mapped. W0 acts as the W register for file register addressing. Some of these registers have a shadow register associated with each of them, as shown in Figure 2-1. The shadow register is used as a temporary holding register and can transfer its contents to or from its host register upon the occurrence of an event. None of the shadow registers are accessible directly. The following rules apply for transfer of registers into and out of shadows. * PUSH.S and POP.S W0, W1, W2, W3, SR (DC, N, OV, Z and C bits only) are transferred. * DO instruction DOSTART, DOEND, DCOUNT shadows are pushed on loop start, and popped on loop end. When a byte operation is performed on a working register, only the Least Significant Byte of the target register is affected. However, a benefit of memory mapped working registers is that both the Least and Most Significant Bytes can be manipulated through byte wide data memory space accesses.
SOFTWARE STACK POINTER/ FRAME POINTER
The dsPIC(R) devices contain a software stack. W15 is the dedicated software stack pointer (SP), and will be automatically modified by exception processing and subroutine calls and returns. However, W15 can be referenced by any instruction in the same manner as all other W registers. This simplifies the reading, writing and manipulation of the stack pointer (e.g., creating stack frames). Note: In order to protect against misaligned stack accesses, W15<0> is always clear.
W15 is initialized to 0x0800 during a Reset. The user may reprogram the SP during initialization to any location within data space. W14 has been dedicated as a stack frame pointer as defined by the LNK and ULNK instructions. However, W14 can be referenced by any instruction in the same manner as all other W registers.
2.2.2
STATUS REGISTER
The dsPIC core has a 16-bit Status Register (SR), the LS Byte of which is referred to as the SR Low Byte (SRL) and the MS Byte as the SR High Byte (SRH). See Figure 2-1 for SR layout. SRL contains all the MCU ALU operation status flags (including the Z bit), as well as the CPU Interrupt Priority Level status bits, IPL<2:0>, and the REPEAT active status bit, RA. During exception processing, SRL is concatenated with the MS Byte of the PC to form a complete word value which is then stacked. The upper byte of the SR register contains the DSP Adder/Subtractor status bits, the DO Loop Active bit (DA) and the Digit Carry (DC) status bit.
2.2.3
PROGRAM COUNTER
The Program Counter is 23 bits wide. Bit 0 is always clear. Therefore, the PC can address up to 4M instruction words.

2.3 Divide Support
The dsPIC devices feature a 16/16-bit signed fractional divide operation, as well as 32/16-bit and 16/16-bit signed and unsigned integer divide operations, in the form of single instruction iterative divides. The following instructions and data sizes are supported: 1. 2. 3. 4. 5. DIVF - 16/16 signed fractional divide DIV.sd - 32/16 signed divide DIV.ud - 32/16 unsigned divide DIV.sw - 16/16 signed divide DIV.uw - 16/16 unsigned divide The divide instructions must be executed within a REPEAT loop. Any other form of execution (e.g. a series of discrete divide instructions) will not function correctly because the instruction flow depends on RCOUNT. The divide instruction does not automatically set up the RCOUNT value, and it must, therefore, be explicitly and correctly specified in the REPEAT instruction, as shown in Table 2-1 (REPEAT will execute the target instruction {operand value+1} times). The REPEAT loop count must be set up for 18 iterations of the DIV/DIVF instruction. Thus, a complete divide operation requires 19 cycles. Note: The Divide flow is interruptible. However, the user needs to save the context as appropriate.

DSP Engine
The DSP engine consists of a high speed 17-bit x 17-bit multiplier, a barrel shifter, and a 40-bit adder/ Subtractor (with two target accumulators, round and saturation logic). The dsPIC30F devices have a single instruction flow which can execute either DSP or MCU instructions. Many of the hardware resources are shared between the DSP and MCU instructions. For example, the instruction set has both DSP and MCU Multiply instructions which use the same hardware multiplier. The DSP engine also has the capability to perform inherent accumulator-to-accumulator operations, which require no additional data. These instructions are ADD, SUB and NEG. The DSP engine has various options selected through various bits in the CPU Core Configuration Register (CORCON), as listed below: 1. 2. 3. 4. 5. 6. 7. Fractional or integer DSP multiply (IF). Signed or unsigned DSP multiply (US). Conventional or convergent rounding (RND). Automatic saturation on/off for AccA (SATA). Automatic saturation on/off for AccB (SATB). Automatic saturation on/off for writes to data memory (SATDW). Accumulator Saturation mode selection (ACCSAT). Note: For CORCON layout, see Table 4-2.

2.4.1 MULTIPLIER 2.4.2.1
The 17x17-bit multiplier is capable of signed or unsigned operation and can multiplex its output using a scaler to support either 1.31 fractional (Q31) or 32-bit integer results. Unsigned operands are zero-extended into the 17th bit of the multiplier input value. Signed operands are sign-extended into the 17th bit of the multiplier input value. The output of the 17x17-bit multiplier/ scaler is a 33-bit value, which is sign-extended to 40 bits. Integer data is inherently represented as a signed two's complement value, where the MSB is defined as a sign bit. Generally speaking, the range of an N-bit two's complement integer is -2N-1 to 2N-1 - 1. For a 16-bit integer, the data range is -32768 (0x8000) to 32767 (0x7FFF), including 0. For a 32-bit integer, the data range is -2,147,483,648 (0x8000 0000) to 2,147,483,645 (0x7FFF FFFF). When the multiplier is configured for fractional multiplication, the data is represented as a two's complement fraction, where the MSB is defined as a sign bit and the radix point is implied to lie just after the sign bit (QX format). The range of an N-bit two's complement fraction with this implied radix point is -1.0 to (1-21-N). For a 16-bit fraction, the Q15 data range is -1.0 (0x8000) to 0.999969482 (0x7FFF), including 0 and has a precision of 3.01518x10-5. In Fractional mode, a 16x16 multiply operation generates a 1.31 product, which has a precision of 4.65661x10-10. The same multiplier is used to support the MCU multiply instructions, which include integer 16-bit signed, unsigned and mixed sign multiplies. The MUL instruction may be directed to use byte or word sized operands. Byte operands will direct a 16-bit result, and word operands will direct a 32-bit result to the specified register(s) in the W array.
Adder/Subtractor, Overflow and Saturation
The adder/subtractor is a 40-bit adder with an optional zero input into one side and either true or complement data into the other input. In the case of addition, the carry/borrow input is active high and the other input is true data (not complemented), whereas in the case of subtraction, the carry/borrow input is active low and the other input is complemented. The adder/subtractor generates overflow status bits SA/SB and OA/OB, which are latched and reflected in the status register. * Overflow from bit 39: this is a catastrophic overflow in which the sign of the accumulator is destroyed. * Overflow into guard bits 32 through 39: this is a recoverable overflow. This bit is set whenever all the guard bits are not identical to each other. The adder has an additional saturation block which controls accumulator data saturation, if selected. It uses the result of the adder, the overflow status bits described above, and the SATA/B (CORCON<7:6>) and ACCSAT (CORCON<4>) mode control bits to determine when and to what value to saturate. Six status register bits have been provided to support saturation and overflow; they are: 1. 2. 3. OA: AccA overflowed into guard bits OB: AccB overflowed into guard bits SA: AccA saturated (bit 31 overflow and saturation) or AccA overflowed into guard bits and saturated (bit 39 overflow and saturation) SB: AccB saturated (bit 31 overflow and saturation) or AccB overflowed into guard bits and saturated (bit 39 overflow and saturation) OAB: Logical OR of OA and OB SAB: Logical OR of SA and SB
2.4.2
DATA ACCUMULATORS AND ADDER/SUBTRACTOR
4.
The data accumulator consists of a 40-bit adder/ subtractor with automatic sign extension logic. It can select one of two accumulators (A or B) as its preaccumulation source and post-accumulation destination. For the ADD and LAC instructions, the data to be accumulated or loaded can be optionally scaled via the barrel shifter, prior to accumulation.
5. 6.
The OA and OB bits are modified each time data passes through the adder/Subtractor. When set, they indicate that the most recent operation has overflowed into the accumulator guard bits (bits 32 through 39). The OA and OB bits can also optionally generate an arithmetic warning trap when set and the corresponding overflow trap flag enable bit (OVATEN, OVBTEN) in the INTCON1 register (refer to Section 5.0) is set. This allows the user to take immediate action, for example, to correct system gain.
DS70119D-page 16
Preliminary
2004 Microchip Technology Inc.
dsPIC30F6010
The SA and SB bits are modified each time data passes through the adder/subtractor, but can only be cleared by the user. When set, they indicate that the accumulator has overflowed its maximum range (bit 31 for 32-bit saturation, or bit 39 for 40-bit saturation) and will be saturated (if saturation is enabled). When saturation is not enabled, SA and SB default to bit 39 overflow and thus indicate that a catastrophic overflow has occurred. If the COVTE bit in the INTCON1 register is set, SA and SB bits will generate an arithmetic warning trap when saturation is disabled. The overflow and saturation status bits can optionally be viewed in the Status Register (SR) as the logical OR of OA and OB (in bit OAB) and the logical OR of SA and SB (in bit SAB). This allows programmers to check one bit in the Status Register to determine if either accumulator has overflowed, or one bit to determine if either accumulator has saturated. This would be useful for complex number arithmetic which typically uses both the accumulators. The device supports three Saturation and Overflow modes. 1. Bit 39 Overflow and Saturation: When bit 39 overflow and saturation occurs, the saturation logic loads the maximally positive 9.31 (0x7FFFFFFFFF) or maximally negative 9.31 value (0x8000000000) into the target accumulator. The SA or SB bit is set and remains set until cleared by the user. This is referred to as `super saturation' and provides protection against erroneous data or unexpected algorithm problems (e.g., gain calculations). Bit 31 Overflow and Saturation: When bit 31 overflow and saturation occurs, the saturation logic then loads the maximally positive 1.31 value (0x007FFFFFFF) or maximally negative 1.31 value (0x0080000000) into the target accumulator. The SA or SB bit is set and remains set until cleared by the user. When this Saturation mode is in effect, the guard bits are not used (so the OA, OB or OAB bits are never set). Bit 39 Catastrophic Overflow The bit 39 overflow status bit from the adder is used to set the SA or SB bit, which remain set until cleared by the user. No saturation operation is performed and the accumulator is allowed to overflow (destroying its sign). If the COVTE bit in the INTCON1 register is set, a catastrophic overflow can initiate a trap exception.
2.4.2.2
Accumulator `Write Back'
The MAC class of instructions (with the exception of MPY, MPY.N, ED and EDAC) can optionally write a rounded version of the high word (bits 31 through 16) of the accumulator that is not targeted by the instruction into data space memory. The write is performed across the X bus into combined X and Y address space. The following addressing modes are supported: 1. W13, Register Direct: The rounded contents of the non-target accumulator are written into W13 as a 1.15 fraction. [W13]+=2, Register Indirect with Post-Increment: The rounded contents of the non-target accumulator are written into the address pointed to by W13 as a 1.15 fraction. W13 is then incremented by 2 (for a word write).
2.
2.4.2.3
Round Logic
The round logic is a combinational block, which performs a conventional (biased) or convergent (unbiased) round function during an accumulator write (store). The Round mode is determined by the state of the RND bit in the CORCON register. It generates a 16-bit, 1.15 data value which is passed to the data space write saturation logic. If rounding is not indicated by the instruction, a truncated 1.15 data value is stored and the LS Word is simply discarded. Conventional rounding takes bit 15 of the accumulator, zero-extends it and adds it to the ACCxH word (bits 16 through 31 of the accumulator). If the ACCxL word (bits 0 through 15 of the accumulator) is between 0x8000 and 0xFFFF (0x8000 included), ACCxH is incremented. If ACCxL is between 0x0000 and 0x7FFF, ACCxH is left unchanged. A consequence of this algorithm is that over a succession of random rounding operations, the value will tend to be biased slightly positive. Convergent (or unbiased) rounding operates in the same manner as conventional rounding, except when ACCxL equals 0x8000. If this is the case, the LS bit (bit 16 of the accumulator) of ACCxH is examined. If it is `1', ACCxH is incremented. If it is `0', ACCxH is not modified. Assuming that bit 16 is effectively random in nature, this scheme will remove any rounding bias that may accumulate. The SAC and SAC.R instructions store either a truncated (SAC) or rounded (SAC.R) version of the contents of the target accumulator to data memory, via the X bus (subject to data saturation, see Section 2.4.2.4). Note that for the MAC class of instructions, the accumulator write back operation will function in the same manner, addressing combined MCU (X and Y) data space though the X bus. For this class of instructions, the data is always subject to rounding.

2.4.2.4 Data Space Write Saturation 2.4.3 BARREL SHIFTER
In addition to adder/subtractor saturation, writes to data space may also be saturated, but without affecting the contents of the source accumulator. The data space write saturation logic block accepts a 16-bit, 1.15 fractional value from the round logic block as its input, together with overflow status from the original source (accumulator) and the 16-bit round adder. These are combined and used to select the appropriate 1.15 fractional value as output to write to data space memory. If the SATDW bit in the CORCON register is set, data (after rounding or truncation) is tested for overflow and adjusted accordingly. For input data greater than 0x007FFF, data written to memory is forced to the maximum positive 1.15 value, 0x7FFF. For input data less than 0xFF8000, data written to memory is forced to the maximum negative 1.15 value, 0x8000. The MS bit of the source (bit 39) is used to determine the sign of the operand being tested. If the SATDW bit in the CORCON register is not set, the input data is always passed through unmodified under all conditions. The barrel shifter is capable of performing up to 16-bit arithmetic or logic right shifts, or up to 16-bit left shifts in a single cycle. The source can be either of the two DSP accumulators or the X bus (to support multi-bit shifts of register or memory data). The shifter requires a signed binary value to determine both the magnitude (number of bits) and direction of the shift operation. A positive value will shift the operand right. A negative value will shift the operand left. A value of 0 will not modify the operand. The barrel shifter is 40 bits wide, thereby obtaining a 40-bit result for DSP shift operations and a 16-bit result for MCU shift operations. Data from the X bus is presented to the barrel shifter between bit positions 16 to 31 for right shifts, and bit positions 0 to 15 for left shifts.

3.1.1 DATA ACCESS FROM PROGRAM MEMORY USING TABLE INSTRUCTIONS
A set of Table Instructions are provided to move byte or word sized data to and from program space. 1. TBLRDL: Table Read Low Word: Read the LS Word of the program address; P<15:0> maps to D<15:0>. Byte: Read one of the LS Bytes of the program address; P<7:0> maps to the destination byte when byte select = 0; P<15:8> maps to the destination byte when byte select = 1. TBLWTL: Table Write Low (refer to Section 6.0 for details on Flash Programming). TBLRDH: Table Read High Word: Read the MS Word of the program address; P<23:16> maps to D<7:0>; D<15:8> always be = 0. Byte: Read one of the MS Bytes of the program address; P<23:16> maps to the destination byte when byte select = 0; The destination byte will always be = 0 when byte select = 1. TBLWTH: Table Write High (refer to Section 6.0 for details on Flash Programming).
This architecture fetches 24-bit wide program memory. Consequently, instructions are always aligned. However, as the architecture is modified Harvard, data can also be present in program space. There are two methods by which program space can be accessed; via special table instructions, or through the remapping of a 16K word program space page into the upper half of data space (see Section 3.1.2). The TBLRDL and TBLWTL instructions offer a direct method of reading or writing the LS Word of any address within program space, without going through data space. The TBLRDH and TBLWTH instructions are the only method whereby the upper 8 bits of a program space word can be accessed as data. The PC is incremented by two for each successive 24-bit program word. This allows program memory addresses to directly map to data space addresses. Program memory can thus be regarded as two 16-bit word wide address spaces, residing side by side, each with the same address range. TBLRDL and TBLWTL access the space which contains the LS Data Word, and TBLRDH and TBLWTH access the space which contains the MS Data Byte. Figure 3-2 shows how the EA is created for table operations and data space accesses (PSV = 1). Here, P<23:0> refers to a program space word, whereas D<15:0> refers to a data space word.

DATA ACCESS FROM PROGRAM MEMORY USING PROGRAM SPACE VISIBILITY
The upper 32 Kbytes of data space may optionally be mapped into any 16K word program space page. This provides transparent access of stored constant data from X data space, without the need to use special instructions (i.e., TBLRDL/H, TBLWTL/H instructions). Program space access through the data space occurs if the MS bit of the data space EA is set and program space visibility is enabled, by setting the PSV bit in the Core Control register (CORCON). The functions of CORCON are discussed in Section 2.4, DSP Engine. Data accesses to this area add an additional cycle to the instruction being executed, since two program memory fetches are required. Note that the upper half of addressable data space is always part of the X data space. Therefore, when a DSP operation uses program space mapping to access this memory region, Y data space should typically contain state (variable) data for DSP operations, whereas X data space should typically contain coefficient (constant) data. Although each data space address, 0x8000 and higher, maps directly into a corresponding program memory address (see Figure 3-5), only the lower 16-bits of the 24-bit program word are used to contain the data. The upper 8 bits should be programmed to force an illegal instruction to maintain machine robustness. Refer to the dsPIC30F Programmer's Reference Manual (DS70030) for details on instruction encoding.
Note that by incrementing the PC by 2 for each program memory word, the LS 15 bits of data space addresses directly map to the LS 15 bits in the corresponding program space addresses. The remaining bits are provided by the Program Space Visibility Page register, PSVPAG<7:0>, as shown in Figure 3-5. Note: PSV access is temporarily disabled during Table Reads/Writes.
For instructions that use PSV which are executed outside a REPEAT loop: * The following instructions will require one instruction cycle in addition to the specified execution time: - MAC class of instructions with data operand pre-fetch - MOV instructions - MOV.D instructions * All other instructions will require two instruction cycles in addition to the specified execution time of the instruction. For instructions that use PSV which are executed inside a REPEAT loop: * The following instances will require two instruction cycles in addition to the specified execution time of the instruction: - Execution in the first iteration - Execution in the last iteration - Execution prior to exiting the loop due to an interrupt - Execution upon re-entering the loop after an interrupt is serviced * Any other iteration of the REPEAT loop will allow the instruction, accessing data using PSV, to execute in a single cycle.

3.2
Data Address Space
The core has two data spaces. The data spaces can be considered either separate (for some DSP instructions), or as one unified linear address range (for MCU instructions). The data spaces are accessed using two Address Generation Units (AGUs) and separate data paths.
3.2.1
DATA SPACE MEMORY MAP
The data space memory is split into two blocks, X and Y data space. A key element of this architecture is that Y space is a subset of X space, and is fully contained within X space. In order to provide an apparent linear addressing space, X and Y spaces have contiguous addresses.
When executing any instruction other than one of the MAC class of instructions, the X block consists of the 64 Kbyte data address space (including all Y addresses). When executing one of the MAC class of instructions, the X block consists of the 64 Kbyte data address space excluding the Y address block (for data reads only). In other words, all other instructions regard the entire data memory as one composite address space. The MAC class instructions extract the Y address space from data space and address it using EAs sourced from W10 and W11. The remaining X data space is addressed using W8 and W9. Both address spaces are concurrently accessed only with the MAC class instructions. A data space memory map is shown in Figure 3-6. Figure 3-7 shows a graphical summary of how X and Y data spaces are accessed for MCU and DSP instructions.

3.2.2 DATA SPACES 3.2.3 DATA SPACE WIDTH
The X data space is used by all instructions and supports all addressing modes. There are separate read and write data buses. The X read data bus is the return data path for all instructions that view data space as combined X and Y address space. It is also the X address space data path for the dual operand read instructions (MAC class). The X write data bus is the only write path to data space for all instructions. The X data space also supports Modulo Addressing for all instructions, subject to Addressing mode restrictions. Bit-Reversed Addressing is only supported for writes to X data space. The Y data space is used in concert with the X data space by the MAC class of instructions (CLR, ED, EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide two concurrent data read paths. No writes occur across the Y bus. This class of instructions dedicates two W register pointers, W10 and W11, to always address Y data space, independent of X data space, whereas W8 and W9 always address X data space. Note that during accumulator write back, the data address space is considered a combination of X and Y data spaces, so the write occurs across the X bus. Consequently, the write can be to any address in the entire data space. The Y data space can only be used for the data prefetch operation associated with the MAC class of instructions. It also supports Modulo Addressing for automated circular buffers. Of course, all other instructions can access the Y data address space through the X data path, as part of the composite linear space. The boundary between the X and Y data spaces is defined as shown in Figure 3-6 and is not user programmable. Should an EA point to data outside its own assigned address space, or to a location outside physical memory, an all-zero word/byte will be returned. For example, although Y address space is visible by all non-MAC instructions using any Addressing mode, an attempt by a MAC instruction to fetch data from that space, using W8 or W9 (X space pointers), will return 0x0000. The core data width is 16-bits. All internal registers are organized as 16-bit wide words. Data space memory is organized in byte addressable, 16-bit wide blocks.
3.2.4
DATA ALIGNMENT
To help maintain backward compatibility with PICmicro(R) devices and improve data space memory usage efficiency, the dsPIC30F instruction set supports both word and byte operations. Data is aligned in data memory and registers as words, but all data space EAs resolve to bytes. Data byte reads will read the complete word, which contains the byte, using the LS bit of any EA to determine which byte to select. The selected byte is placed onto the LS Byte of the X data path (no byte accesses are possible from the Y data path as the MAC class of instruction can only fetch words). That is, data memory and registers are organized as two parallel byte wide entities with shared (word) address decode, but separate write lines. Data byte writes only write to the corresponding side of the array or register which matches the byte address. As a consequence of this byte accessibility, all effective address calculations (including those generated by the DSP operations, which are restricted to word sized data) are internally scaled to step through word aligned memory. For example, the core would recognize that Post-Modified Register Indirect Addressing mode, [Ws++], will result in a value of Ws+1 for byte operations and Ws+2 for word operations. All word accesses must be aligned to an even address. Mis-aligned word data fetches are not supported, so care must be taken when mixing byte and word operations, or translating from 8-bit MCU code. Should a misaligned read or write be attempted, an Address Error trap will be generated. If the error occurred on a read, the instruction underway is completed, whereas if it occurred on a write, the instruction will be executed but the write will not occur. In either case, a trap will then be executed, allowing the system and/or user to examine the machine state prior to execution of the address fault.

dsPIC30F6010
All byte loads into any W register are loaded into the LS Byte. The MSB is not modified. A sign-extend (SE) instruction is provided to allow users to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, users can clear the MSB of any W register by executing a zero-extend (ZE) instruction on the appropriate address. Although most instructions are capable of operating on word or byte data sizes, it should be noted that some instructions, including the DSP instructions, operate only on words. There is a Stack Pointer Limit register (SPLIM) associated with the stack pointer. SPLIM is uninitialized at Reset. As is the case for the stack pointer, SPLIM<0> is forced to `0', because all stack operations must be word aligned. Whenever an effective address (EA) is generated using W15 as a source or destination pointer, the address thus generated is compared with the value in SPLIM. If the contents of the Stack Pointer (W15) and the SPLIM register are equal and a push operation is performed, a Stack Error Trap will not occur. The Stack Error Trap will occur on a subsequent push operation. Thus, for example, if it is desirable to cause a Stack Error Trap when the stack grows beyond address 0x2000 in RAM, initialize the SPLIM with the value, 0x1FFE. Similarly, a Stack Pointer Underflow (Stack Error) trap is generated when the stack pointer address is found to be less than 0x0800, thus preventing the stack from interfering with the Special Function Register (SFR) space. A write to the SPLIM register should not be immediately followed by an indirect read operation using W15.
3.2.5
NEAR DATA SPACE
An 8 Kbyte `near' data space is reserved in X address memory space between 0x0000 and 0x1FFF, which is directly addressable via a 13-bit absolute address field within all memory direct instructions. The remaining X address space and all of the Y address space is addressable indirectly. Additionally, the whole of X data space is addressable using MOV instructions, which support memory direct addressing with a 16-bit address field.

The dsPIC device contains a software stack. W15 is used as the Stack Pointer. The stack pointer always points to the first available free word and grows from lower addresses towards higher addresses. It pre-decrements for stack pops and post-increments for stack pushes, as shown in Figure 3-9. Note that for a PC push during any CALL instruction, the MSB of the PC is zero-extended before the push, ensuring that the MSB is always clear. Note: A PC push during exception processing will concatenate the SRL register to the MSB of the PC prior to the push.

4.0 ADDRESS GENERATOR UNITS
4.1.1 FILE REGISTER INSTRUCTIONS
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046). For more information on the device instruction set and programming, refer to the dsPIC30F Programmer's Reference Manual (DS70030).
The dsPIC core contains two independent address generator units: the X AGU and Y AGU. The Y AGU supports word sized data reads for the DSP MAC class of instructions only. The dsPIC AGUs support three types of data addressing: * Linear Addressing * Modulo (Circular) Addressing * Bit-Reversed Addressing Linear and Modulo Data Addressing modes can be applied to data space or program space. Bit-Reversed addressing is only applicable to data space addresses.
Most file register instructions use a 13-bit address field (f) to directly address data present in the first 8192 bytes of data memory (near data space). Most file register instructions employ a working register W0, which is denoted as WREG in these instructions. The destination is typically either the same file register, or WREG (with the exception of the MUL instruction), which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can access the entire data space during file register operation.
4.1.2
MCU INSTRUCTIONS
The three-operand MCU instructions are of the form: Operand 3 = Operand 1 Operand 2 where Operand 1 is always a working register (i.e., the addressing mode can only be register direct), which is referred to as Wb. Operand 2 can be a W register, fetched from data memory, or a 5-bit literal. The result location can be either a W register or an address location. The following addressing modes are supported by MCU instructions: * * * * * Register Direct Register Indirect Register Indirect Post-modified Register Indirect Pre-modified 5-bit or 10-bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes.
4.1
Instruction Addressing Modes
The addressing modes in Table 4-1 form the basis of the addressing modes optimized to support the specific features of individual instructions. The addressing modes provided in the MAC class of instructions are somewhat different from those in the other instruction types.
TABLE 4-1:
FUNDAMENTAL ADDRESSING MODES SUPPORTED

Wn is post-modified (incremented or decremented) by a constant value. Wn is pre-modified (incremented or decremented) by a signed constant value to form the EA. The sum of Wn and a literal forms the EA.

4.1.3 MOVE AND ACCUMULATOR INSTRUCTIONS
In summary, the following addressing modes are supported by the MAC class of instructions: * * * * * Register Indirect Register Indirect Post-modified by 2 Register Indirect Post-modified by 4 Register Indirect Post-modified by 6 Register Indirect with Register Offset (Indexed) Move instructions and the DSP Accumulator class of instructions provide a greater degree of addressing flexibility than other instructions. In addition to the addressing modes supported by most MCU instructions, Move and Accumulator instructions also support Register Indirect with Register Offset Addressing mode, also referred to as Register Indexed mode. Note: For the MOV instructions, the addressing mode specified in the instruction can differ for the source and destination EA. However, the 4-bit Wb (Register Offset) field is shared between both source and destination (but typically only used by one).
4.1.5
OTHER INSTRUCTIONS
In summary, the following addressing modes are supported by Move and Accumulator instructions: * * * * * * * * Register Direct Register Indirect Register Indirect Post-modified Register Indirect Pre-modified Register Indirect with Register Offset (Indexed) Register Indirect with Literal Offset 8-bit Literal 16-bit Literal Note: Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes.
Besides the various addressing modes outlined above, some instructions use literal constants of various sizes. For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI instruction uses a 14-bit unsigned literal field. In some instructions, such as ADD Acc, the source of an operand or result is implied by the opcode itself. Certain operations, such as NOP, do not have any operands.
4.2
Modulo Addressing
Modulo addressing is a method of providing an automated means to support circular data buffers using hardware. The objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many DSP algorithms. Modulo addressing can operate in either data or program space (since the data pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into Program space) and Y data spaces. Modulo addressing can operate on any W register pointer. However, it is not advisable to use W14 or W15 for Modulo addressing, since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. In general, any particular circular buffer can only be configured to operate in one direction, as there are certain restrictions on the buffer start address (for incrementing buffers) or end address (for decrementing buffers) based upon the direction of the buffer. The only exception to the usage restrictions is for buffers which have a power-of-2 length. As these buffers satisfy the start and end address criteria, they may operate in a Bi-directional mode, (i.e., address boundary checks will be performed on both the lower and upper address boundaries).
4.1.4
MAC INSTRUCTIONS
The dual source operand DSP instructions (CLR, ED, EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred to as MAC instructions, utilize a simplified set of addressing modes to allow the user to effectively manipulate the data pointers through register indirect tables. The two source operand pre-fetch registers must be a member of the set {W8, W9, W10, W11}. For data reads, W8 and W9 will always be directed to the X RAGU and W10 and W11 will always be directed to the Y AGU. The effective addresses generated (before and after modification) must, therefore, be valid addresses within X data space for W8 and W9 and Y data space for W10 and W11. Note: Register Indirect with Register Offset Addressing is only available for W9 (in X space) and W11 (in Y space).

4.2.1 START AND END ADDRESS 4.2.2
The Modulo addressing scheme requires that a starting and an end address be specified and loaded into the 16-bit modulo buffer address registers: XMODSRT, XMODEND, YMODSRT and YMODEND (see Table 3-3).. Note: Y-space modulo addressing EA calculations assume word-sized data (LS bit of every EA is always clear).
W ADDRESS REGISTER SELECTION
The Modulo and Bit-Reversed Addressing Control register MODCON<15:0> contains enable flags as well as a W register field to specify the W address registers. The XWM and YWM fields select which registers will operate with modulo addressing. If XWM = 15, X RAGU and X WAGU modulo addressing are disabled. Similarly, if YWM = 15, Y AGU modulo addressing is disabled. The X Address Space Pointer W register (XWM) to which modulo addressing is to be applied, is stored in MODCON<3:0> (see Table 3-3). Modulo addressing is enabled for X data space when XWM is set to any value other than 15 and the XMODEN bit is set at MODCON<15>. The Y Address Space Pointer W register (YWM) to which modulo addressing is to be applied, is stored in MODCON<7:4>. Modulo addressing is enabled for Y data space when YWM is set to any value other than 15 and the YMODEN bit is set at MODCON<14>.
The length of a circular buffer is not directly specified. It is determined by the difference between the corresponding start and end addresses. The maximum possible length of the circular buffer is 32K words (64 Kbytes).

4.2.3 MODULO ADDRESSING APPLICABILITY
Modulo addressing can be applied to the effective address (EA) calculation associated with any W register. It is important to realize that the address boundaries check for addresses less than or greater than the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). Address changes may, therefore, jump beyond boundaries and still be adjusted correctly. Note: The modulo corrected effective address is written back to the register only when PreModify or Post-Modify Addressing mode is used to compute the Effective Address. When an address offset (e.g., [W7+W2]) is used, modulo address correction is performed, but the contents of the register remains unchanged. If the length of a bit-reversed buffer is M = 2N bytes, then the last 'N' bits of the data buffer start address must be zeros. XB<14:0> is the bit-reversed address modifier or `pivot point' which is typically a constant. In the case of an FFT computation, its value is equal to half of the FFT data buffer size. Note: All Bit-Reversed EA calculations assume word sized data (LS bit of every EA is always clear). The XB value is scaled accordingly to generate compatible (byte) addresses.
4.3
Bit-Reversed Addressing
Bit-Reversed addressing is intended to simplify data reordering for radix-2 FFT algorithms. It is supported by the X AGU for data writes only. The modifier, which may be a constant value or register contents, is regarded as having its bit order reversed. The address source and destination are kept in normal order. Thus, the only operand requiring reversal is the modifier.
When enabled, bit-reversed addressing will only be executed for register indirect with pre-increment or post-increment addressing and word sized data writes. It will not function for any other addressing mode or for byte-sized data, and normal addresses will be generated instead. When bit-reversed addressing is active, the W address pointer will always be added to the address modifier (XB) and the offset associated with the Register Indirect Addressing mode will be ignored. In addition, as word sized data is a requirement, the LS bit of the EA is ignored (and always clear). Note: Modulo addressing and bit-reversed addressing should not be enabled together. In the event that the user attempts to do this, bit reversed addressing will assume priority when active for the X WAGU, and X WAGU modulo addressing will be disabled. However, modulo addressing will continue to function in the X RAGU.
4.3.1
BIT-REVERSED ADDRESSING IMPLEMENTATION
Bit-Reversed addressing is enabled when: 1. BWM (W register selection) in the MODCON register is any value other than 15 (the stack can not be accessed using bit-reversed addressing) and the BREN bit is set in the XBREV register and the addressing mode used is Register Indirect with Pre-Increment or Post-Increment.
If bit-reversed addressing has already been enabled by setting the BREN (XBREV<15>) bit, then a write to the XBREV register should not be immediately followed by an indirect read operation using the W register that has been designated as the bit-reversed pointer.

5.0 INTERRUPTS
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046). For more information on the device instruction set and programming, refer to the dsPIC30F Programmer's Reference Manual (DS70030).
The dsPIC30F6010 has 44 interrupt sources and 4 processor exceptions (traps), which must be arbitrated based on a priority scheme. The CPU is responsible for reading the Interrupt Vector Table (IVT) and transferring the address contained in the interrupt vector to the program counter. The interrupt vector is transferred from the program data bus into the program counter, via a 24-bit wide multiplexer on the input of the program counter. The Interrupt Vector Table (IVT) and Alternate Interrupt Vector Table (AIVT) are placed near the beginning of program memory (0x000004). The IVT and AIVT are shown in Figure 5-1. The interrupt controller is responsible for preprocessing the interrupts and processor exceptions, prior to their being presented to the processor core. The peripheral interrupts and traps are enabled, prioritized and controlled using centralized special function registers: * IFS0<15:0>, IFS1<15:0>, IFS2<15:0> All interrupt request flags are maintained in these three registers. The flags are set by their respective peripherals or external signals, and they are cleared via software. * IEC0<15:0>, IEC1<15:0>, IEC2<15:0> All Interrupt Enable Control bits are maintained in these three registers. These control bits are used to individually enable interrupts from the peripherals or external signals. * IPC0<15:0>... IPC11<7:0> The user assignable priority level associated with each of these 44 interrupts is held centrally in these twelve registers. * IPL<3:0> The current CPU priority level is explicitly stored in the IPL bits. IPL<3> is present in the CORCON register, whereas IPL<2:0> are present in the status register (SR) in the processor core. * INTCON1<15:0>, INTCON2<15:0> Global interrupt control functions are derived from these two registers. INTCON1 contains the control and status flags for the processor exceptions. The INTCON2 register controls the external interrupt request signal behavior and the use of the alternate vector table.
Interrupt Flag bits get set when an interrupt condition occurs, regardless of the state of its corresponding Enable bit. User software should ensure the appropriate Interrupt Flag bits are clear prior to enabling an interrupt. All interrupt sources can be user assigned to one of seven priority levels, 1 through 7, via the IPCx registers. Each interrupt source is associated with an interrupt vector, as shown in Table 5-1. Levels 7 and 1 represent the highest and lowest maskable priorities, respectively. Note: Assigning a priority level of 0 to an interrupt source is equivalent to disabling that interrupt.
Note:
If the NSTDIS bit (INTCON1<15>) is set, nesting of interrupts is prevented. Thus, if an interrupt is currently being serviced, processing of a new interrupt is prevented, even if the new interrupt is of higher priority than the one currently being serviced. Note: The IPL bits become read-only whenever the NSTDIS bit has been set to `1'.
Certain interrupts have specialized control bits for features like edge or level triggered interrupts, interrupt-on-change, etc. Control of these features remains within the peripheral module which generates the interrupt. The DISI instruction can be used to disable the processing of interrupts of priorities 6 and lower for a certain number of instructions, during which the DISI bit (INTCON2<14>) remains set. When an interrupt is serviced, the PC is loaded with the address stored in the vector location in Program Memory that corresponds to the interrupt. There are 63 different vectors within the IVT (refer to Figure 5-2). These vectors are contained in locations 0x000004 through 0x0000FE of program memory (refer to Figure 5-2). These locations contain 24-bit addresses, and in order to preserve robustness, an address error trap will take place should the PC attempt to fetch any of these words during normal execution. This prevents execution of random data as a result of accidentally decrementing a PC into vector space, accidentally mapping a data space address into vector space, or the PC rolling over to 0x000000 after reaching the end of implemented program memory space. Execution of a GOTO instruction to this vector space will also generate an address error trap.

5.1 Interrupt Priority
TABLE 5-1: INTERRUPT VECTOR TABLE
Interrupt Source
The user assignable Interrupt Priority (IP<2:0>) bits for each individual interrupt source are located in the LS 3bits of each nibble, within the IPCx register(s). Bit 3 of each nibble is not used and is read as a `0'. These bits define the priority level assigned to a particular interrupt by the user. Note: The user selectable priority levels start at 0, as the lowest priority, and level 7, as the highest priority.
INT Vector Number Number
Since more than one interrupt request source may be assigned to a specific user specified priority level, a means is provided to assign priority within a given level. This method is called "Natural Order Priority". Natural Order Priority is determined by the position of an interrupt in the vector table, and only affects interrupt operation when multiple interrupts with the same user-assigned priority become pending at the same time. Table 5-1 lists the interrupt numbers and interrupt sources for the dsPIC devices and their associated vector numbers. Note 1: The natural order priority scheme has 0 as the highest priority and 53 as the lowest priority. 2: The natural order priority number is the same as the INT number. The ability for the user to assign every interrupt to one of seven priority levels implies that the user can assign a very high overall priority level to an interrupt with a low natural order priority. For example, the PLVD (Low Voltage Detect) can be given a priority of 7. The INT0 (external interrupt 0) may be assigned to priority level 1, thus giving it a very low effective priority.

5.2 Reset Sequence 5.3 Traps
A Reset is not a true exception, because the interrupt controller is not involved in the Reset process. The processor initializes its registers in response to a Reset, which forces the PC to zero. The processor then begins program execution at location 0x000000. A GOTO instruction is stored in the first program memory location, immediately followed by the address target for the GOTO instruction. The processor executes the GOTO to the specified address and then begins operation at the specified target (start) address. Traps can be considered as non-maskable interrupts indicating a software or hardware error, which adhere to a predefined priority as shown in Figure 5-1. They are intended to provide the user a means to correct erroneous operation during debug and when operating within the application. Note: If the user does not intend to take corrective action in the event of a trap error condition, these vectors must be loaded with the address of a default handler that simply contains the RESET instruction. If, on the other hand, one of the vectors containing an invalid address is called, an address error trap is generated.
5.2.1
RESET SOURCES
There are 6 sources of error which will cause a device reset. * Watchdog Time-out: The watchdog has timed out, indicating that the processor is no longer executing the correct flow of code. * Uninitialized W Register Trap: An attempt to use an uninitialized W register as an address pointer will cause a Reset. * Illegal Instruction Trap: Attempted execution of any unused opcodes will result in an illegal instruction trap. Note that a fetch of an illegal instruction does not result in an illegal instruction trap if that instruction is flushed prior to execution due to a flow change. * Brown-out Reset (BOR): A momentary dip in the power supply to the device has been detected, which may result in malfunction. * Trap Lockout: Occurrence of multiple Trap conditions simultaneously will cause a Reset.
Note that many of these trap conditions can only be detected when they occur. Consequently, the questionable instruction is allowed to complete prior to trap exception processing. If the user chooses to recover from the error, the result of the erroneous action that caused the trap may have to be corrected. There are 8 fixed priority levels for traps: Level 8 through Level 15, which implies that the IPL3 is always set during processing of a trap. If the user is not currently executing a trap, and he sets the IPL<3:0> bits to a value of `0111' (Level 7), then all interrupts are disabled, but traps can still be processed.
5.3.1
TRAP SOURCES
The following traps are provided with increasing priority. However, since all traps can be nested, priority has little effect.
Math Error Trap:
The Math Error trap executes under the following three circumstances: 1. Should an attempt be made to divide by zero, the divide operation will be aborted on a cycle boundary and the trap taken. If enabled, a Math Error trap will be taken when an arithmetic operation on either accumulator A or B causes an overflow from bit 31 and the Accumulator Guard bits are not utilized. If enabled, a Math Error trap will be taken when an arithmetic operation on either accumulator A or B causes a catastrophic overflow from bit 39 and all saturation is disabled. If the shift amount specified in a shift instruction is greater than the maximum allowed shift amount, a trap will occur.

Address Error Trap:
This trap is initiated when any of the following circumstances occurs: 1. 2. 3. 4. A misaligned data word access is attempted. A data fetch from our unimplemented data memory location is attempted. A data access of an unimplemented program memory location is attempted. An instruction fetch from vector space is attempted. Note: In the MAC class of instructions, wherein the data space is split into X and Y data space, unimplemented X space includes all of Y space, and unimplemented Y space includes all of X space.
5.3.2
HARD AND SOFT TRAPS
It is possible that multiple traps can become active within the same cycle (e.g., a misaligned word stack write to an overflowed address). In such a case, the fixed priority shown in Figure 5-2 is implemented, which may require the user to check if other traps are pending, in order to completely correct the fault. `Soft' traps include exceptions of priority level 8 through level 11, inclusive. The arithmetic error trap (level 11) falls into this category of traps. `Hard' traps include exceptions of priority level 12 through level 15, inclusive. The address error (level 12), stack error (level 13) and oscillator error (level 14) traps fall into this category. Each hard trap that occurs must be acknowledged before code execution of any type may continue. If a lower priority hard trap occurs while a higher priority trap is pending, acknowledged, or is being processed, a hard trap conflict will occur. The device is automatically Reset in a hard trap conflict condition. The TRAPR status bit (RCON<15>) is set when the Reset occurs, so that the condition may be detected in software.
5.
6.
Execution of a "BRA #literal" instruction or a "GOTO #literal" instruction, where literal is an unimplemented program memory address. Executing instructions after modifying the PC to point to unimplemented program memory addresses. The PC may be modified by loading a value into the stack and executing a RETURN instruction.
Stack Error Trap:
This trap is initiated under the following conditions: 1. The stack pointer is loaded with a value which is greater than the (user programmable) limit value written into the SPLIM register (stack overflow). The stack pointer is loaded with a value which is less than 0x0800 (simple stack underflow).

5.4 Interrupt Sequence 5.5 Alternate Vector Table
All interrupt event flags are sampled in the beginning of each instruction cycle by the IFSx registers. A pending interrupt request (IRQ) is indicated by the flag bit being equal to a `1' in an IFSx register. The IRQ will cause an interrupt to occur if the corresponding bit in the interrupt enable (IECx) register is set. For the remainder of the instruction cycle, the priorities of all pending interrupt requests are evaluated. If there is a pending IRQ with a priority level greater than the current processor priority level in the IPL bits, the processor will be interrupted. The processor then stacks the current program counter and the low byte of the processor status register (SRL), as shown in Figure 5-2. The low byte of the status register contains the processor priority level at the time, prior to the beginning of the interrupt cycle. The processor then loads the priority level for this interrupt into the status register. This action will disable all lower priority interrupts until the completion of the Interrupt Service Routine. In Program Memory, the Interrupt Vector Table (IVT) is followed by the Alternate Interrupt Vector Table (AIVT), as shown in Figure 5-1. Access to the Alternate Vector Table is provided by the ALTIVT bit in the INTCON2 register. If the ALTIVT bit is set, all interrupt and exception processes will use the alternate vectors instead of the default vectors. The alternate vectors are organized in the same manner as the default vectors. The AIVT supports emulation and debugging efforts by providing a means to switch between an application and a support environment, without requiring the interrupt vectors to be reprogrammed. This feature also enables switching between applications for evaluation of different software algorithms at run time. If the AIVT is not required, the program memory allocated to the AIVT may be used for other purposes. AIVT is not a protected section and may be freely programmed by the user.
5.6
Fast Context Saving
FIGURE 5-2:
0x0000 15 Stack Grows Towards Higher Address

A context saving option is available using shadow registers. Shadow registers are provided for the DC, N, OV, Z and C bits in SR, and the registers W0 through W3. The shadows are only one level deep. The shadow registers are accessible using the PUSH.S and POP.S instructions only. When the processor vectors to an interrupt, the PUSH.S instruction can be used to store the current value of the aforementioned registers into their respective shadow registers. If an ISR of a certain priority uses the PUSH.S and POP.S instructions for fast context saving, then a higher priority ISR should not include the same instructions. Users must save the key registers in software during a lower priority interrupt, if the higher priority ISR uses fast context saving.
PC<15:0> SRL IPL3 PC<22:16>
W15 (before CALL) W15 (after CALL)
POP : [--W15] PUSH : [W15++]

Note 1: The user can always lower the priority level by writing a new value into SR. The Interrupt Service Routine must clear the interrupt flag bits in the IFSx register before lowering the processor interrupt priority, in order to avoid recursive interrupts. 2: The IPL3 bit (CORCON<3>) is always clear when interrupts are being processed. It is set only during execution of traps.
5.7
External Interrupt Requests
The interrupt controller supports five external interrupt request signals, INT0-INT4. These inputs are edge sensitive; they require a low-to-high or a high-to-low transition to generate an interrupt request. The INTCON2 register has five bits, INT0EP-INT4EP, that select the polarity of the edge detection circuitry.
The RETFIE (Return from Interrupt) instruction will unstack the program counter and status registers to return the processor to its state prior to the interrupt sequence.
5.8
Wake-up from Sleep and Idle
The interrupt controller may be used to wake up the processor from either Sleep or Idle modes, if Sleep or Idle mode is active when the interrupt is generated. If an enabled interrupt request of sufficient priority is received by the interrupt controller, then the standard interrupt request is presented to the processor. At the same time, the processor will wake-up from Sleep or Idle and begin execution of the Interrupt Service Routine (ISR) needed to process the interrupt request.

Run Time Self-Programming (RTSP)
RTSP is accomplished using TBLRD (table read) and TBLWT (table write) instructions. With RTSP, the user may erase program memory, 32 instructions (96 bytes) at a time and can write program memory data, 32 instructions (96 bytes) at a time.
The dsPIC30F family of devices contains internal program Flash memory for executing user code. There are two methods by which the user can program this memory: 1. 2. In-Circuit Serial ProgrammingTM (ICSPTM) Run Time Self-Programming (RTSP)
6.3
Table Instruction Operation Summary
The TBLRDL and the TBLWTL instructions are used to read or write to bits <15:0> of program memory. TBLRDL and TBLWTL can access program memory in Word or Byte mode. The TBLRDH and TBLWTH instructions are used to read or write to bits<23:16> of program memory. TBLRDH and TBLWTH can access program memory in Word or Byte mode. A 24-bit program memory address is formed using bits<7:0> of the TBLPAG register and the effective address (EA) from a W register specified in the table instruction, as shown in Figure 6-1.
6.1
In-Circuit Serial Programming (ICSP)
dsPIC30F devices can be serially programmed while in the end application circuit. This is simply done with two lines for Programming Clock and Programming Data (which are named PGC and PGD respectively), and three other lines for Power (VDD), Ground (VSS) and Master Clear (MCLR). this allows customers to manufacture boards with unprogrammed devices, and then program the microcontroller just before shipping the product. This also allows the most recent firmware or a custom firmware to be programmed.

6.4 RTSP Operation 6.5 RTSP Control Registers
The dsPIC30F Flash program memory is organized into rows and panels. Each row consists of 32 instructions, or 96 bytes. Each panel consists of 128 rows, or 4K x 24 instructions. RTSP allows the user to erase one row (32 instructions) at a time and to program 32 instructions at one time. Each panel of program memory contains write latches that hold 32 instructions of programming data. Prior to the actual programming operation, the write data must be loaded into the panel write latches. The data to be programmed into the panel is loaded in sequential order into the write latches; instruction 0, instruction 1, etc. The addresses loaded must always be from an even group of 32 boundary. The basic sequence for RTSP programming is to set up a table pointer, then do a series of TBLWT instructions to load the write latches. Programming is performed by setting the special bits in the NVMCON register. 32 TBLWTL and 32 TBLWTH instructions are required to load the 32 instructions. All of the table write operations are single word writes (2 instruction cycles), because only the table latches are written. After the latches are written, a programming operation needs to be initiated to program the data. The Flash Program Memory is readable, writable and erasable during normal operation over the entire VDD range. The four SFRs used to read and write the program Flash memory are: * * * * NVMCON NVMADR NVMADRU NVMKEY
6.5.1
NVMCON REGISTER
The NVMCON register controls which blocks are to be erased, which memory type is to be programmed, and start of the programming cycle.
6.5.2
NVMADR REGISTER
The NVMADR register is used to hold the lower two bytes of the effective address. The NVMADR register captures the EA<15:0> of the last table instruction that has been executed and selects the row to write.
6.5.3
NVMADRU REGISTER
The NVMADRU register is used to hold the upper byte of the effective address. The NVMADRU register captures the EA<23:16> of the last table instruction that has been executed.
6.5.4
NVMKEY REGISTER
NVMKEY is a write-only register that is used for write protection. To start a programming or an erase sequence, the user must consecutively write 0x55 and 0xAA to the NVMKEY register. Refer to Section 6.6 for further details. Note: The user can also directly write to the NVMADR and NVMADRU registers to specify a program memory address for erasing or programming.

6.6 Programming Operations
4. A complete programming sequence is necessary for programming or erasing the internal Flash in RTSP mode. A programming operation is nominally 2 msec in duration and the processor stalls (waits) until the operation is finished. Setting the WR bit (NVMCON<15>) starts the operation, and the WR bit is automatically cleared when the operation is finished. Write 32 instruction words of data from data RAM "image" into the program Flash write latches. Program 32 instruction words into program Flash. a) Setup NVMCON register for multi-word, program Flash, program, and set WREN bit. b) Write `55' to NVMKEY. c) Write `AA' to NVMKEY. d) Set the WR bit. This will begin program cycle. e) CPU will stall for duration of the program cycle. f) The WR bit is cleared by the hardware when program cycle ends. Repeat steps 1 through 5 as needed to program desired amount of program Flash memory.
5.
6.6.1
PROGRAMMING ALGORITHM FOR PROGRAM FLASH
The user can erase or program one row of program Flash memory at a time. The general process is: 1. Read one row of program Flash (32 instruction words) and store into data RAM as a data "image". Update the data image with the desired new data. Erase program Flash row. a) Setup NVMCON register for multi-word, program Flash, erase, and set WREN bit. b) Write address of row to be erased into NVMADRU/NVMDR. c) Write `55' to NVMKEY. d) Write `AA' to NVMKEY. e) Set the WR bit. This will begin erase cycle. f) CPU will stall for the duration of the erase cycle. g) The WR bit is cleared when erase cycle ends.

6.6.3 LOADING WRITE LATCHES
Example 6-2 shows a sequence of instructions that can be used to load the 96 bytes of write latches. 32 TBLWTL and 32 TBLWTH instructions are needed to load the write latches selected by the table pointer.
EXAMPLE 6-2:

Note: In Example 6-2, the contents of the upper byte of W3 has no effect.
6.6.4
INITIATING THE PROGRAMMING SEQUENCE
For protection, the write initiate sequence for NVMKEY must be used to allow any erase or program operation to proceed. After the programming command has been executed, the user must wait for the programming time until programming is complete. The two instructions following the start of the programming sequence should be NOPs.
EXAMPLE 6-3:

7.0 DATA EEPROM MEMORY
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046). For more information on the device instruction set and programming, refer to the dsPIC30F Programmer's Reference Manual (DS70030).
A program or erase operation on the data EEPROM does not stop the instruction flow. The user is responsible for waiting for the appropriate duration of time before initiating another data EEPROM write/erase operation. Attempting to read the data EEPROM while a programming or erase operation is in progress results in unspecified data. Control bit WR initiates write operations, similar to program Flash writes. This bit cannot be cleared, only set, in software. This bit is cleared in hardware at the completion of the write operation. The inability to clear the WR bit in software prevents the accidental or premature termination of a write operation. The WREN bit, when set, will allow a write operation. On power-up, the WREN bit is clear. The WRERR bit is set when a write operation is interrupted by a MCLR Reset, or a WDT Time-out Reset, during normal operation. In these situations, following Reset, the user can check the WRERR bit and rewrite the location. The address register NVMADR remains unchanged. Note: Interrupt flag bit NVMIF in the IFS0 register is set when write is complete. It must be cleared in software.
The Data EEPROM Memory is readable and writable during normal operation over the entire VDD range. The data EEPROM memory is directly mapped in the program memory address space. The four SFRs used to read and write the program Flash memory are used to access data EEPROM memory, as well. As described in Section 4.0, these registers are: * * * * NVMCON NVMADR NVMADRU NVMKEY
The EEPROM data memory allows read and write of single words and 16-word blocks. When interfacing to data memory, NVMADR, in conjunction with the NVMADRU register, is used to address the EEPROM location being accessed. TBLRDL and TBLWTL instructions are used to read and write data EEPROM. The dsPIC30F6010 device has 8 Kbytes (4K words) of data EEPROM, with an address range from 0x7FF000 to 0x7FFFFE. A word write operation should be preceded by an erase of the corresponding memory location(s). The write typically requires 2 ms to complete, but the write time will vary with voltage and temperature.
7.1
Reading the Data EEPROM
A TBLRD instruction reads a word at the current program word address. This example uses W0 as a pointer to data EEPROM. The result is placed in register W4, as shown in Example 7-1.

Erasing Data EEPROM
ERASING A BLOCK OF DATA EEPROM
In order to erase a block of data EEPROM, the NVMADRU and NVMADR registers must initially point to the block of memory to be erased. Configure NVMCON for erasing a block of data EEPROM, and set the ERASE and WREN bits in NVMCON register. Setting the WR bit initiates the erase, as shown in Example 7-2.
EXAMPLE 7-2:
DATA EEPROM BLOCK ERASE
; Select data EEPROM block, ERASE, WREN bits MOV #4045,W0 ; Initialize NVMCON SFR MOV W0,NVMCON ; Start erase cycle by setting WR after writing key sequence DISI #5 ; Block all interrupts with priority <7 ; for next 5 instructions MOV #0x55,W0 ; ; Write the 0x55 key MOV W0,NVMKEY MOV #0xAA,W1 ; MOV W1,NVMKEY ; Write the 0xAA key BSET NVMCON,#WR ; Initiate erase sequence NOP NOP ; Erase cycle will complete in 2mS. CPU is not stalled for the Data Erase Cycle ; User can poll WR bit, use NVMIF or Timer IRQ to determine erasure complete
7.2.2
ERASING A WORD OF DATA EEPROM
The NVMADRU and NVMADR registers must point to the block. Select erase a block of data Flash, and set the ERASE and WREN bits in NVMCON register. Setting the WR bit initiates the erase, as shown in Example 7-3.
EXAMPLE 7-3:

7.3 Writing to the Data EEPROM
To write an EEPROM data location, the following sequence must be followed: 1. Erase data EEPROM word. a) Select word, data EEPROM, erase and set WREN bit in NVMCON register. b) Write address of word to be erased into NVMADRU/NVMADR. c) Enable NVM interrupt (optional). d) Write `55' to NVMKEY. e) Write `AA' to NVMKEY. f) Set the WR bit. This will begin erase cycle. g) Either poll NVMIF bit or wait for NVMIF interrupt. h) The WR bit is cleared when the erase cycle ends. Write data word into data EEPROM write latches. Program 1 data word into data EEPROM. a) Select word, data EEPROM, program, and set WREN bit in NVMCON register. b) Enable NVM write done interrupt (optional). c) Write `55' to NVMKEY. d) Write `AA' to NVMKEY. e) Set The WR bit. This will begin program cycle. f) Either poll NVMIF bit or wait for NVM interrupt. g) The WR bit is cleared when the write cycle ends. The write will not initiate if the above sequence is not exactly followed (write 0x55 to NVMKEY, write 0xAA to NVMCON, then set WR bit) for each word. It is strongly recommended that interrupts be disabled during this code segment. Additionally, the WREN bit in NVMCON must be set to enable writes. This mechanism prevents accidental writes to data EEPROM, due to unexpected code execution. The WREN bit should be kept clear at all times, except when updating the EEPROM. The WREN bit is not cleared by hardware. After a write sequence has been initiated, clearing the WREN bit will not affect the current write cycle. The WR bit will be inhibited from being set unless the WREN bit is set. The WREN bit must be set on a previous instruction. Both WR and WREN cannot be set with the same instruction. At the completion of the write cycle, the WR bit is cleared in hardware and the Non-Volatile Memory Write Complete Interrupt Flag bit (NVMIF) is set. The user may either enable this interrupt, or poll this bit. NVMIF must be cleared by software.

Write Verify
7.5
Protection Against Spurious Write
Depending on the application, good programming practice may dictate that the value written to the memory should be verified against the original value. This should be used in applications where excessive writes can stress bits near the specification limit.
There are conditions when the device may not want to write to the data EEPROM memory. To protect against spurious EEPROM writes, various mechanisms have been built-in. On power-up, the WREN bit is cleared; also, the Power-up Timer prevents EEPROM write. The write initiate sequence and the WREN bit together, help prevent an accidental write during brown-out, power glitch or software malfunction.

8.0 I/O PORTS
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
Any bit and its associated data and control registers that are not valid for a particular device will be disabled. That means the corresponding LATx and TRISx registers and the port pin will read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs. An example is the INT4 pin. The format of the registers for PORTA are shown in Table 8-1. The TRISA (Data Direction Control) register controls the direction of the RA<7:0> pins, as well as the INTx pins and the VREF pins. The LATA register supplies data to the outputs, and is readable/writable. Reading the PORTA register yields the state of the input pins, while writing the PORTA register modifies the contents of the LATA register. A parallel I/O (PIO) port that shares a pin with a peripheral is, in general, subservient to the peripheral. The peripheral's output buffer data and control signals are provided to a pair of multiplexers. The multiplexers select whether the peripheral or the associated port has ownership of the output data and control signals of the I/O pad cell. Figure 8-2 shows how ports are shared with other peripherals, and the associated I/O cell (pad) to which they are connected. Table 8-1 shows the formats of the registers for the shared ports, PORTB through PORTG.
All of the device pins (except VDD, VSS, MCLR and OSC1/CLKIN) are shared between the peripherals and the parallel I/O ports. All I/O input ports feature Schmitt Trigger inputs for improved noise immunity.
8.1
Parallel I/O (PIO) Ports
When a peripheral is enabled and the peripheral is actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. The I/O pin may be read, but the output driver for the Parallel Port bit will be disabled. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin may be driven by a port. All port pins have three registers directly associated with the operation of the port pin. The data direction register (TRISx) determines whether the pin is an input or an output. If the Data Direction bit is a `1', then the pin is an input. All port pins are defined as inputs after a Reset. Reads from the latch (LATx), read the latch. Writes to the latch, write the latch (LATx). Reads from the port (PORTx), read the port pins, and writes to the port pins, write the latch (LATx).

Configuring Analog Port Pins
8.2.1
I/O PORT WRITE/READ TIMING
The use of the ADPCFG and TRIS registers control the operation of the A/D port pins. The port pins that are desired as analog inputs must have their corresponding TRIS bit set (input). If the TRIS bit is cleared (output), the digital output level (VOH or VOL) will be converted. When reading the PORT register, all pins configured as analog input channel will read as cleared (a low level). Pins configured as digital inputs will not convert an analog input. Analog levels on any pin that is defined as a digital input (including the ANx pins), may cause the input buffer to consume current that exceeds the device specifications.
One instruction cycle is required between a port direction change or port write operation and a read operation of the same port. Typically this instruction would be a NOP.
EXAMPLE 8-1:

8.3 Input Change Notification Module
The Input Change Notification module provides the dsPIC30F devices the ability to generate interrupt requests to the processor in response to a change-ofstate on selected input pins. This module is capable of detecting input change-of-states even in Sleep mode, when the clocks are disabled. There are 22 external signals (CN0 through CN21) that may be selected (enabled) for generating an interrupt request on a change-of-state. Please refer to the Pin Diagram on page 3 for CN pin locations.

9.0 TIMER1 MODULE
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
These operating modes are determined by setting the appropriate bit(s) in the 16-bit SFR, T1CON. Figure 9-1 presents a block diagram of the 16-bit timer module. 16-bit Timer Mode: In the 16-bit Timer mode, the timer increments on every instruction cycle up to a match value, preloaded into the period register PR1, then resets to 0 and continues to count. When the CPU goes into the Idle mode, the timer will stop incrementing, unless the TSIDL (T1CON<13>) bit = 0. If TSIDL = 1, the timer module logic will resume the incrementing sequence upon termination of the CPU Idle mode. 16-bit Synchronous Counter Mode: In the 16-bit Synchronous Counter mode, the timer increments on the rising edge of the applied external clock signal, which is synchronized with the internal phase clocks. The timer counts up to a match value preloaded in PR1, then resets to 0 and continues. When the CPU goes into the Idle mode, the timer will stop incrementing, unless the respective TSIDL bit = 0. If TSIDL = 1, the timer module logic will resume the incrementing sequence upon termination of the CPU Idle mode. 16-bit Asynchronous Counter Mode: In the 16-bit Asynchronous Counter mode, the timer increments on every rising edge of the applied external clock signal. The timer counts up to a match value preloaded in PR1, then resets to 0 and continues. When the timer is configured for the Asynchronous mode of operation and the CPU goes into the Idle mode, the timer will stop incrementing if TSIDL = 1.
This section describes the 16-bit General Purpose (GP) Timer1 module and associated operational modes. Note: Timer1 is a `Type A' timer. Please refer to the specifications for a Type A timer in Section 24.0 Electrical Characteristics of this document.
The following sections provide a detailed description, including setup and control registers along with associated block diagrams for the operational modes of the timers. The Timer1 module is a 16-bit timer which can serve as the time counter for the real-time clock, or operate as a free running interval timer/counter. The 16-bit timer has the following modes: * 16-bit Timer * 16-bit Synchronous Counter * 16-bit Asynchronous Counter Further, the following operational characteristics are supported: * Timer gate operation * Selectable prescaler settings * Timer operation during CPU Idle and Sleep modes * Interrupt on 16-bit period register match or falling edge of external gate signal

Timer Gate Operation
9.3
The 16-bit timer can be placed in the Gated Time Accumulation mode. This mode allows the internal TCY to increment the respective timer when the gate input signal (T1CK pin) is asserted high. Control bit TGATE (T1CON<6>) must be set to enable this mode. The timer must be enabled (TON = 1) and the timer clock source set to internal (TCS = 0). When the CPU goes into the Idle mode, the timer will stop incrementing, unless TSIDL = 0. If TSIDL = 1, the timer will resume the incrementing sequence upon termination of the CPU Idle mode.
Timer Operation During Sleep Mode
During CPU Sleep mode, the timer will operate if: * The timer module is enabled (TON = 1) and * The timer clock source is selected as external (TCS = 1) and * The TSYNC bit (T1CON<2>) is asserted to a logic 0, which defines the external clock source as asynchronous When all three conditions are true, the timer will continue to count up to the period register and be reset to 0x0000. When a match between the timer and the period register occurs, an interrupt can be generated, if the respective Timer Interrupt Enable bit is asserted.
9.2
Timer Prescaler
The input clock (FOSC/4 or external clock) to the 16-bit Timer, has a prescale option of 1:1, 1:8, 1:64, and 1:256 selected by control bits TCKPS<1:0> (T1CON<5:4>). The prescaler counter is cleared when any of the following occurs: * a write to the TMR1 register * clearing of the TON bit (T1CON<15>) * device Reset such as POR and BOR However, if the timer is disabled (TON = 0), then the timer prescaler cannot be reset since the prescaler clock is halted. TMR1 is not cleared when T1CON is written. It is cleared by writing to the TMR1 register.

9.4 Timer Interrupt
9.5.1 RTC OSCILLATOR OPERATION
The 16-bit timer has the ability to generate an interrupt on period match. When the timer count matches the period register, the T1IF bit is asserted and an interrupt will be generated, if enabled. The T1IF bit must be cleared in software. The timer interrupt flag T1IF is located in the IFS0 control register in the Interrupt Controller. When the Gated Time Accumulation mode is enabled, an interrupt will also be generated on the falling edge of the gate signal (at the end of the accumulation cycle). Enabling an interrupt is accomplished via the respective Timer Interrupt Enable bit, T1IE. The Timer Interrupt Enable bit is located in the IEC0 control register in the Interrupt Controller. When the TON = 1, TCS = 1 and TGATE = 0, the timer increments on the rising edge of the 32 kHz LP oscillator output signal, up to the value specified in the period register, and is then reset to `0'. The TSYNC bit must be asserted to a logic `0' (Asynchronous mode) for correct operation. Enabling LPOSCEN (OSCCON<1>) will disable the normal Timer and Counter modes and enable a timer carry-out wake-up event. When the CPU enters Sleep mode, the RTC will continue to operate, provided the 32 kHz external crystal oscillator is active and the control bits have not been changed. The TSIDL bit should be cleared to `0' in order for RTC to continue operation in Idle mode.

Real-Time Clock
9.5.2
RTC INTERRUPTS
Timer1, when operating in Real-Time Clock (RTC) mode, provides time-of-day and event time stamping capabilities. Key operational features of the RTC are: * * * * Operation from 32 kHz LP oscillator 8-bit prescaler Low power Real-Time Clock Interrupts
When an interrupt event occurs, the respective interrupt flag, T1IF, is asserted and an interrupt will be generated, if enabled. The T1IF bit must be cleared in software. The respective Timer interrupt flag, T1IF, is located in the IFS0 status register in the Interrupt Controller. Enabling an interrupt is accomplished via the respective Timer Interrupt Enable bit, T1IE. The Timer Interrupt Enable bit is located in the IEC0 control register in the Interrupt Controller.
These Operating modes are determined by setting the appropriate bit(s) in the T1CON Control register

10.0 TIMER2/3 MODULE
For 32-bit timer/counter operation, Timer2 is the LS Word and Timer3 is the MS Word of the 32-bit timer. Note: For 32-bit timer operation, T3CON control bits are ignored. Only T2CON control bits are used for setup and control. Timer 2 clock and gate inputs are utilized for the 32-bit timer module, but an interrupt is generated with the Timer3 interrupt flag (T3IF) and the interrupt is enabled with the Timer3 Interrupt Enable bit (T3IE).
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
This section describes the 32-bit General Purpose (GP) Timer module (Timer2/3) and associated operational modes. Figure 10-1 depicts the simplified block diagram of the 32-bit Timer2/3 module. Figure 10-2 and Figure 10-3 show Timer2/3 configured as two independent 16-bit timers; Timer2 and Timer3, respectively. Note: Timer2 is a `Type B' timer and Timer3 is a `Type C' timer. Please refer to the appropriate timer type in Section 24.0 Electrical Characteristics of this document.
16-bit Mode: In the 16-bit mode, Timer2 and Timer3 can be configured as two independent 16-bit timers. Each timer can be set up in either 16-bit Timer mode or 16-bit Synchronous Counter mode. See Section 9.0, Timer1 Module, for details on these two operating modes. The only functional difference between Timer2 and Timer3 is that Timer2 provides synchronization of the clock prescaler output. This is useful for high frequency external clock inputs. 32-bit Timer Mode: In the 32-bit Timer mode, the timer increments on every instruction cycle up to a match value, preloaded into the combined 32-bit period register PR3/PR2, then resets to 0 and continues to count. For synchronous 32-bit reads of the Timer2/Timer3 pair, reading the LS word (TMR2 register) will cause the MS word to be read and latched into a 16-bit holding register, termed TMR3HLD. For synchronous 32-bit writes, the holding register (TMR3HLD) must first be written to. When followed by a write to the TMR2 register, the contents of TMR3HLD will be transferred and latched into the MSB of the 32-bit timer (TMR3). 32-bit Synchronous Counter Mode: In the 32-bit Synchronous Counter mode, the timer increments on the rising edge of the applied external clock signal, which is synchronized with the internal phase clocks. The timer counts up to a match value preloaded in the combined 32-bit period register PR3/PR2, then resets to `0' and continues. When the timer is configured for the Synchronous Counter mode of operation and the CPU goes into the Idle mode, the timer will stop incrementing, unless the TSIDL (T2CON<13>) bit = 0. If TSIDL = 1, the timer module logic will resume the incrementing sequence upon termination of the CPU Idle mode.
The Timer2/3 module is a 32-bit timer, which can be configured as two 16-bit timers, with selectable operating modes. These timers are utilized by other peripheral modules such as: * Input Capture * Output Compare/Simple PWM The following sections provide a detailed description, including setup and control registers, along with associated block diagrams for the operational modes of the timers. The 32-bit timer has the following modes: * Two independent 16-bit timers (Timer2 and Timer3) with all 16-bit operating modes (except Asynchronous Counter mode) * Single 32-bit Timer operation * Single 32-bit Synchronous Counter Further, the following operational characteristics are supported: * * * * * ADC Event Trigger Timer Gate Operation Selectable Prescaler Settings Timer Operation during Idle and Sleep modes Interrupt on a 32-bit Period Register Match
These operating modes are determined by setting the appropriate bit(s) in the 16-bit T2CON and T3CON SFRs.

10.1 Timer Gate Operation 10.4
The 32-bit timer can be placed in the Gated Time Accumulation mode. This mode allows the internal TCY to increment the respective timer when the gate input signal (T2CK pin) is asserted high. Control bit TGATE (T2CON<6>) must be set to enable this mode. When in this mode, Timer2 is the originating clock source. The TGATE setting is ignored for Timer3. The timer must be enabled (TON = 1) and the timer clock source set to internal (TCS = 0). The falling edge of the external signal terminates the count operation, but does not reset the timer. The user must reset the timer in order to start counting from zero.
Timer Operation During Sleep Mode
During CPU Sleep mode, the timer will not operate, because the internal clocks are disabled.
10.5
Timer Interrupt
10.2
ADC Event Trigger
The 32-bit timer module can generate an interrupt on period match, or on the falling edge of the external gate signal. When the 32-bit timer count matches the respective 32-bit period register, or the falling edge of the external "gate" signal is detected, the T3IF bit (IFS0<7>) is asserted and an interrupt will be generated if enabled. In this mode, the T3IF interrupt flag is used as the source of the interrupt. The T3IF bit must be cleared in software. Enabling an interrupt is accomplished via the respective Timer Interrupt Enable bit, T3IE (IEC0<7>).
When a match occurs between the 32-bit timer (TMR3/ TMR2) and the 32-bit combined period register (PR3/ PR2), a special ADC trigger event signal is generated by Timer3.
10.3
Timer Prescaler
The input clock (FOSC/4 or external clock) to the timer has a prescale option of 1:1, 1:8, 1:64, and 1:256 selected by control bits TCKPS<1:0> (T2CON<5:4> and T3CON<5:4>). For the 32-bit timer operation, the originating clock source is Timer2. The prescaler operation for Timer3 is not applicable in this mode. The prescaler counter is cleared when any of the following occurs: * a write to the TMR2/TMR3 register * clearing either of the TON (T2CON<15> or T3CON<15>) bits to `0' * device Reset such as POR and BOR However, if the timer is disabled (TON = 0), then the Timer 2 prescaler cannot be reset, since the prescaler clock is halted. TMR2/TMR3 is not cleared when T2CON/T3CON is written.

11.0 TIMER4/5 MODULE
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
The Timer4/5 module is similar in operation to the Timer 2/3 module. However, there are some differences, which are listed below: * The Timer4/5 module does not support the ADC Event Trigger feature * Timer4/5 can not be utilized by other peripheral modules such as Input Capture and Output Compare The operating modes of the Timer4/5 module are determined by setting the appropriate bit(s) in the 16-bit T4CON and T5CON SFRs. For 32-bit timer/counter operation, Timer4 is the LS Word and Timer5 is the MS Word of the 32-bit timer. Note: For 32-bit timer operation, T5CON control bits are ignored. Only T4CON control bits are used for setup and control. Timer4 clock and gate inputs are utilized for the 32-bit timer module, but an interrupt is generated with the Timer5 interrupt flag (T5IF) and the interrupt is enabled with the Timer5 Interrupt Enable bit (T5IE).
This section describes the second 32-bit General Purpose (GP) Timer module (Timer4/5) and associated operational modes. Figure 11-1 depicts the simplified block diagram of the 32-bit Timer4/5 Module. Figure 11-2 and Figure 11-3 show Timer4/5 configured as two independent 16-bit timers, Timer4 and Timer5, respectively. Note: Timer4 is a `Type B' timer and Timer5 is a `Type C' timer.

Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
The simple capture events in the dsPIC30F product family are: * * * * * Capture every falling edge Capture every rising edge Capture every 4th rising edge Capture every 16th rising edge Capture every rising and falling edge
This section describes the Input Capture module and associated operational modes. The features provided by this module are useful in applications requiring Frequency (Period) and Pulse measurement. Figure 12-1 depicts a block diagram of the Input Capture module. Input capture is useful for such modes as: * Frequency/Period/Pulse Measurements * Additional sources of External Interrupts The key operational features of the Input Capture module are: * Simple Capture Event mode * Timer2 and Timer3 mode selection * Interrupt on input capture event These operating modes are determined by setting the appropriate bits in the ICxCON register (where x = 1,2,...,N). The dsPIC30F6010 device has 8 capture channels.
These simple Input Capture modes are configured by setting the appropriate bits ICM<2:0> (ICxCON<2:0>).

There are four input capture prescaler settings, specified by bits ICM<2:0> (ICxCON<2:0>). Whenever the capture channel is turned off, the prescaler counter will be cleared. In addition, any Reset will clear the prescaler counter.

12.1.2 CAPTURE BUFFER OPERATION
12.2
Each capture channel has an associated FIFO buffer, which is four 16-bit words deep. There are two status flags, which provide status on the FIFO buffer: * ICBFNE - Input Capture Buffer Not Empty * ICOV - Input Capture Overflow The ICBFNE will be set on the first input capture event and remain set until all capture events have been read from the FIFO. As each word is read from the FIFO, the remaining words are advanced by one position within the buffer. In the event that the FIFO is full with four capture events and a fifth capture event occurs prior to a read of the FIFO, an overflow condition will occur and the ICOV bit will be set to a logic `1'. The fifth capture event is lost and is not stored in the FIFO. No additional events will be captured till all four events have been read from the buffer. If a FIFO read is performed after the last read and no new capture event has been received, the read will yield indeterminate results.
Input Capture Operation During Sleep and Idle Modes
An input capture event will generate a device wake-up or interrupt, if enabled, if the device is in CPU Idle or Sleep mode. Independent of the timer being enabled, the input capture module will wake-up from the CPU Sleep or Idle mode when a capture event occurs, if ICM<2:0> = 111 and the Interrupt Enable bit is asserted. The same wake-up can generate an interrupt, if the conditions for processing the interrupt have been satisfied. The wake-up feature is useful as a method of adding extra external pin interrupts.
12.2.1
INPUT CAPTURE IN CPU SLEEP MODE
CPU Sleep mode allows input capture module operation with reduced functionality. In the CPU Sleep mode, the ICI<1:0> bits are not applicable, and the input capture module can only function as an external interrupt source. The capture module must be configured for interrupt only on the rising edge (ICM<2:0> = 111), in order for the input capture module to be used while the device is in Sleep mode. The prescale settings of 4:1 or 16:1 are not applicable in this mode.
12.1.3
TIMER2 AND TIMER3 SELECTION MODE
Each capture channel can select between one of two timers for the time base, Timer2 or Timer3. Selection of the timer resource is accomplished through SFR bit ICTMR (ICxCON<7>). Timer3 is the default timer resource available for the input capture module.
12.2.2
INPUT CAPTURE IN CPU IDLE MODE
12.1.4
HALL SENSOR MODE
When the input capture module is set for capture on every edge, rising and falling, ICM<2:0> = 001, the following operations are performed by the input capture logic: * The input capture interrupt flag is set on every edge, rising and falling. * The interrupt on Capture mode setting bits, ICI<1:0>, is ignored, since every capture generates an interrupt. * A capture overflow condition is not generated in this mode.
CPU Idle mode allows input capture module operation with full functionality. In the CPU Idle mode, the Interrupt mode selected by the ICI<1:0> bits are applicable, as well as the 4:1 and 16:1 capture prescale settings, which are defined by control bits ICM<2:0>. This mode requires the selected timer to be enabled. Moreover, the ICSIDL bit must be asserted to a logic `0'. If the input capture module is defined as ICM<2:0> = 111 in CPU Idle mode, the input capture pin will serve only as an external interrupt pin.
12.3
Input Capture Interrupts
The input capture channels have the ability to generate an interrupt, based upon the selected number of capture events. The selection number is set by control bits ICI<1:0> (ICxCON<6:5>). Each channel provides an interrupt flag (ICxIF) bit. The respective capture channel interrupt flag is located in the corresponding IFSx Status register. Enabling an interrupt is accomplished via the respective capture channel interrupt enable (ICxIE) bit. The Capture Interrupt Enable bit is located in the corresponding IEC Control register.

13.0 OUTPUT COMPARE MODULE
The key operational features of the Output Compare module include: * * * * * * Timer2 and Timer3 Selection mode Simple Output Compare Match mode Dual Output Compare Match mode Simple PWM mode Output Compare during Sleep and Idle modes Interrupt on Output Compare/PWM Event
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
This section describes the Output Compare module and associated operational modes. The features provided by this module are useful in applications requiring operational modes such as: * Generation of Variable Width Output Pulses * Power Factor Correction Figure 13-1 depicts a block diagram of the Output Compare module.
These operating modes are determined by setting the appropriate bits in the 16-bit OCxCON SFR (where x = 1,2,3,...,N). The dsPIC30F6010 device has 8 compare channels. OCxRS and OCxR in the figure represent the Dual Compare registers. In the Dual Compare mode, the OCxR register is used for the first compare and OCxRS is used for the second compare.

13.1 Timer2 and Timer3 Selection Mode
13.3.2 CONTINUOUS PULSE MODE
Each output compare channel can select between one of two 16-bit timers; Timer2 or Timer3. The selection of the timers is controlled by the OCTSEL bit (OCxCON<3>). Timer2 is the default timer resource for the Output Compare module. For the user to configure the module for the generation of a continuous stream of output pulses, the following steps are required: * Determine instruction cycle time TCY. * Calculate desired pulse value based on TCY. * Calculate timer to start pulse width from timer start value of 0x0000. * Write pulse width start and stop times into OCxR and OCxRS (x denotes channel 1, 2, ...,N) compare registers, respectively. * Set timer period register to value equal to, or greater than, value in OCxRS compare register. * Set OCM<2:0> = 101. * Enable timer, TON (TxCON<15>) = 1.
13.2
Simple Output Compare Match Mode
When control bits OCM<2:0> (OCxCON<2:0>) = 001, 010 or 011, the selected output compare channel is configured for one of three simple output compare match modes: * Compare forces I/O pin low * Compare forces I/O pin high * Compare toggles I/O pin The OCxR register is used in these modes. The OCxR register is loaded with a value and is compared to the selected incrementing timer count. When a compare occurs, one of these compare match modes occurs. If the counter resets to zero before reaching the value in OCxR, the state of the OCx pin remains unchanged.
13.4
Simple PWM Mode
When control bits OCM<2:0> (OCxCON<2:0>) = 110 or 111, the selected output compare channel is configured for the PWM mode of operation. When configured for the PWM mode of operation, OCxR is the Main latch (read only) and OCxRS is the Secondary latch. This enables glitchless PWM transitions. The user must perform the following steps in order to configure the output compare module for PWM operation: 1. 2. 3. 4. Set the PWM period by writing to the appropriate period register. Set the PWM duty cycle by writing to the OCxRS register. Configure the output compare module for PWM operation. Set the TMRx prescale value and enable the Timer, TON (TxCON<15>) = 1.
13.3
Dual Output Compare Match Mode
When control bits OCM<2:0> (OCxCON<2:0>) = 100 or 101, the selected output compare channel is configured for one of two dual output compare modes, which are: * Single Output Pulse mode * Continuous Output Pulse mode
13.3.1
SINGLE PULSE MODE
For the user to configure the module for the generation of a single output pulse, the following steps are required (assuming timer is off): * Determine instruction cycle time TCY. * Calculate desired pulse width value based on TCY. * Calculate time to start pulse from timer start value of 0x0000. * Write pulse width start and stop times into OCxR and OCxRS compare registers (x denotes channel 1, 2, ...,N). * Set timer period register to value equal to, or greater than, value in OCxRS compare register. * Set OCM<2:0> = 100. * Enable timer, TON (TxCON<15>) = 1. To initiate another single pulse, issue another write to set OCM<2:0> = 100.
13.4.1
INPUT PIN FAULT PROTECTION FOR PWM
When control bits OCM<2:0> (OCxCON<2:0>) = 111, the selected output compare channel is again configured for the PWM mode of operation, with the additional feature of input fault protection. While in this mode, if a logic 0 is detected on the OCFA/B pin, the respective PWM output pin is placed in the high impedance input state. The OCFLT bit (OCxCON<4>) indicates whether a FAULT condition has occurred. This state will be maintained until both of the following events have occurred: * The external FAULT condition has been removed. * The PWM mode has been re-enabled by writing to the appropriate control bits.

13.4.2 PWM PERIOD
The PWM period is specified by writing to the PRx register. The PWM period can be calculated using Equation 13-1. When the selected TMRx is equal to its respective period register, PRx, the following four events occur on the next increment cycle: * TMRx is cleared. * The OCx pin is set. - Exception 1: If PWM duty cycle is 0x0000, the OCx pin will remain low. - Exception 2: If duty cycle is greater than PRx, the pin will remain high. * The PWM duty cycle is latched from OCxRS into OCxR. * The corresponding timer interrupt flag is set. See Figure 13-1 for key PWM period comparisons. Timer3 is referred to in the figure for clarity.
EQUATION 13-1:
PWM PERIOD
PWM period = [(PRx) + 1] * 4 * TOSC * (TMRx prescale value) PWM frequency is defined as 1 / [PWM period].

13.5
Output Compare Operation During CPU Sleep Mode
13.7
Output Compare Interrupts
When the CPU enters the Sleep mode, all internal clocks are stopped. Therefore, when the CPU enters the Sleep state, the output compare channel will drive the pin to the active state that was observed prior to entering the CPU Sleep state. For example, if the pin was high when the CPU entered the Sleep state, the pin will remain high. Likewise, if the pin was low when the CPU entered the Sleep state, the pin will remain low. In either case, the output compare module will resume operation when the device wakes up.
The output compare channels have the ability to generate an interrupt on a compare match, for whichever match mode has been selected. For all modes except the PWM mode, when a compare event occurs, the respective interrupt flag (OCxIF) is asserted and an interrupt will be generated, if enabled. The OCxIF bit is located in the corresponding IFS Status register, and must be cleared in software. The interrupt is enabled via the respective compare interrupt enable (OCxIE) bit, located in the corresponding IEC Control register. For the PWM mode, when an event occurs, the respective timer interrupt flag (T2IF or T3IF) is asserted and an interrupt will be generated, if enabled. The IF bit is located in the IFS0 Status register, and must be cleared in software. The interrupt is enabled via the respective Timer Interrupt Enable bit (T2IE or T3IE), located in the IEC0 Control register. The output compare interrupt flag is never set during the PWM mode of operation.
13.6
Output Compare Operation During CPU Idle Mode
When the CPU enters the Idle mode, the output compare module can operate with full functionality. The output compare channel will operate during the CPU Idle mode if the OCSIDL bit (OCxCON<13>) is at logic 0 and the selected time base (Timer2 or Timer3) is enabled and the TSIDL bit of the selected timer is set to logic 0.

14.0 QUADRATURE ENCODER INTERFACE (QEI) MODULE
The operational features of the QEI include: * Three input channels for two phase signals and index pulse * 16-bit up/down position counter * Count direction status * Position Measurement (x2 and x4) mode * Programmable digital noise filters on inputs * Alternate 16-bit Timer/Counter mode * Quadrature Encoder Interface interrupts These operating modes are determined by setting the appropriate bits QEIM<2:0> (QEICON<10:8>).

14.1 Quadrature Encoder Interface Logic
A typical incremental (a.k.a. optical) encoder has three outputs: Phase A, Phase B, and an index pulse. These signals are useful and often required in position and speed control of ACIM and SR motors. The two channels, Phase A (QEA) and Phase B (QEB), have a unique relationship. If Phase A leads Phase B, then the direction (of the motor) is deemed positive or forward. If Phase A lags Phase B, then the direction (of the motor) is deemed negative or reverse. A third channel, termed index pulse, occurs once per revolution and is used as a reference to establish an absolute position. The index pulse coincides with Phase A and Phase B, both low. If the POSRES bit is set to `1', then the position counter is reset when the index pulse is detected. If the POSRES bit is set to `0', then the position counter is not reset when the index pulse is detected. The position counter will continue counting up or down, and will be reset on the rollover or underflow condition. The interrupt is still generated on the detection of the index pulse and not on the position counter overflow/ underflow.
14.2.3
COUNT DIRECTION STATUS
14.2
16-bit Up/Down Position Counter Mode
As mentioned in the previous section, the QEI logic generates an UPDN signal, based upon the relationship between Phase A and Phase B. In addition to the output pin, the state of this internal UPDN signal is supplied to a SFR bit UPDN (QEICON<11>) as a read only bit. To place the state of this signal on an I/O pin, the SFR bit PCDOUT (QEICON<6>) must be 1.
The 16-bit Up/Down Counter counts up or down on every count pulse, which is generated by the difference of the Phase A and Phase B input signals. The counter acts as an integrator, whose count value is proportional to position. The direction of the count is determined by the UPDN signal, which is generated by the Quadrature Encoder Interface Logic.
14.3
Position Measurement Mode
There are two measurement modes which are supported and are termed x2 and x4. These modes are selected by the QEIM<2:0> mode select bits located in SFR QEICON<10:8>. When control bits QEIM<2:0> = 100 or 101, the x2 Measurement mode is selected and the QEI logic only looks at the Phase A input for the position counter increment rate. Every rising and falling edge of the Phase A signal causes the position counter to be incremented or decremented. The Phase B signal is still utilized for the determination of the counter direction, just as in the x4 mode. Within the x2 Measurement mode, there are two variations of how the position counter is reset: 1. 2. Position counter reset by detection of index pulse, QEIM<2:0> = 100. Position counter reset by match with MAXCNT, QEIM<2:0> = 101.
14.2.1
POSITION COUNTER ERROR CHECKING
Position count error checking in the QEI is provided for and indicated by the CNTERR bit (QEICON<15>). The error checking only applies when the position counter is configured for Reset on the Index Pulse modes (QEIM<2:0> = `110' or `100'). In these modes, the contents of the POSCNT register is compared with the values (0xFFFF or MAXCNT+1, depending on direction). If these values are detected, an error condition is generated by setting the CNTERR bit and a QEI count error interrupt is generated. The QEI count error interrupt can be disabled by setting the CEID bit (DFLTCON<8>). The position counter continues to count encoder edges after an error has been detected. The POSCNT register continues to count up/down until a natural rollover/underflow. No interrupt is generated for the natural rollover/underflow event. The CNTERR bit is a Read/Write bit and reset in software by the user.
When control bits QEIM<2:0> = 110 or 111, the x4 Measurement mode is selected and the QEI logic looks at both edges of the Phase A and Phase B input signals. Every edge of both signals causes the position counter to increment or decrement. Within the x4 Measurement mode, there are two variations of how the position counter is reset: 1. 2. Position counter reset by detection of index pulse, QEIM<2:0> = 110. Position counter reset by match with MAXCNT, QEIM<2:0> = 111.
14.2.2
POSITION COUNTER RESET
The Position Counter Reset Enable bit, POSRES (QEI<2>) controls whether the position counter is reset when the index pulse is detected. This bit is only applicable when QEIM<2:0> = `100' or `110'.
The x4 Measurement mode provides for finer resolution data (more position counts) for determining motor position.

14.4 Programmable Digital Noise Filters
The digital noise filter section is responsible for rejecting noise on the incoming capture or quadrature signals. Schmitt Trigger inputs and a three-clock cycle delay filter combine to reject low level noise and large, short duration noise spikes that typically occur in noise prone applications, such as a motor system. The filter ensures that the filtered output signal is not permitted to change until a stable value has been registered for three consecutive clock cycles. For the QEA, QEB and INDX pins, the clock divide frequency for the digital filter is programmed by bits QECK<2:0> (DFLTCON<6:4>) and are derived from the base instruction cycle TCY. To enable the filter output for channels QEA, QEB and INDX, the QEOUT bit must be `1'. The filter network for all channels is disabled on POR and BOR. In addition, control bit UPDN_SRC (QEICON<0>) determines whether the timer count direction state is based on the logic state, written into the UPDN Control/ Status bit (QEICON<11>), or the QEB pin state. When UPDN_SRC = 1, the timer count direction is controlled from the QEB pin. Likewise, when UPDN_SRC = 0, the timer count direction is controlled by the UPDN bit. Note: This Timer does not support the External Asynchronous Counter mode of operation. If using an external clock source, the clock will automatically be synchronized to the internal instruction cycle.

Alternate 16-bit Timer/Counter
The QEI module will be halted during the CPU Sleep mode.
When the QEI module is not configured for the QEI mode QEIM<2:0> = 001, the module can be configured as a simple 16-bit timer/counter. The setup and control of the auxiliary timer is accomplished through the QEICON SFR register. This timer functions identically to Timer1. The QEA pin is used as the timer clock input. When configured as a timer, the POSCNT register serves as the Timer Count Register and the MAXCNT register serves as the Period Register. When a timer/ period register match occur, the QEI interrupt flag will be asserted. The only exception between the general purpose timers and this timer is the added feature of external Up/ Down input select. When the UPDN pin is asserted high, the timer will increment up. When the UPDN pin is asserted low, the timer will be decremented. Note: Changing the operational mode (i.e., from QEI to Timer or vice versa), will not affect the Timer/Position Count Register contents.

During CPU Sleep mode, the timer will not operate, because the internal clocks are disabled.
14.7
QEI Module Operation During CPU Idle Mode
Since the QEI module can function as a quadrature encoder interface, or as a 16-bit timer, the following section describes operation of the module in both modes.
14.7.1
QEI OPERATION DURING CPU IDLE MODE
When the CPU is placed in the Idle mode, the QEI module will operate if the QEISIDL bit (QEICON<13>) = 0. This bit defaults to a logic `0' upon executing POR and BOR. For halting the QEI module during the CPU Idle mode, QEISIDL should be set to `1'.
The UPDN Control/Status bit (QEICON<11>) can be used to select the count direction state of the Timer register. When UPDN = 1, the timer will count up. When UPDN = 0, the timer will count down.

14.8
Quadrature Encoder Interface Interrupts
When the CPU is placed in the Idle mode and the QEI module is configured in the 16-bit Timer mode, the 16-bit timer will operate if the QEISIDL bit (QEICON<13>) = 0. This bit defaults to a logic `0' upon executing POR and BOR. For halting the timer module during the CPU Idle mode, QEISIDL should be set to `1'. If the QEISIDL bit is cleared, the timer will function normally, as if the CPU Idle mode had not been entered.
The quadrature encoder interface has the ability to generate an interrupt on occurrence of the following events: * Interrupt on 16-bit up/down position counter rollover/underflow * Detection of qualified index pulse, or if CNTERR bit is set * Timer period match event (overflow/underflow) * Gate accumulation event The QEI Interrupt Flag bit, QEIIF, is asserted upon occurrence of any of the above events. The QEIIF bit must be cleared in software. QEIIF is located in the IFS2 Status register. Enabling an interrupt is accomplished via the respective Enable bit, QEIIE. The QEIIE bit is located in the IEC2 Control register.

15.1 PWM Time Base
15.1.1 FREE RUNNING MODE
The PWM time base is provided by a 15-bit timer with a prescaler and postscaler. The time base is accessible via the PTMR SFR. PTMR<15> is a Read Only Status bit, PTDIR, that indicates the present count direction of the PWM time base. If PTDIR is cleared, PTMR is counting upwards. If PTDIR is set, PTMR is counting downwards. The PWM time base is configured via the PTCON SFR. The time base is enabled/disabled by setting/clearing the PTEN bit in the PTCON SFR. PTMR is not cleared when the PTEN bit is cleared in software. The PTPER SFR sets the counting period for PTMR. The user must write a 15-bit value to PTPER<14:0>. When the value in PTMR<14:0> matches the value in PTPER<14:0>, the time base will either reset to 0, or reverse the count direction on the next occurring clock cycle. The action taken depends on the operating mode of the time base. Note: If the period register is set to 0x0000, the timer will stop counting, and the interrupt and the special event trigger will not be generated, even if the special event value is also 0x0000. The module will not update the period register, if it is already at 0x0000; therefore, the user must disable the module in order to update the period register. In the Free Running mode, the PWM time base counts upwards until the value in the Time Base Period register (PTPER) is matched. The PTMR register is reset on the following input clock edge and the time base will continue to count upwards as long as the PTEN bit remains set. When the PWM time base is in the Free Running mode (PTMOD<1:0> = 00), an interrupt event is generated each time a match with the PTPER register occurs and the PTMR register is reset to zero. The postscaler selection bits may be used in this mode of the timer to reduce the frequency of the interrupt events.
15.1.2
SINGLE SHOT MODE
In the Single Shot Counting mode, the PWM time base begins counting upwards when the PTEN bit is set. When the value in the PTMR register matches the PTPER register, the PTMR register will be reset on the following input clock edge and the PTEN bit will be cleared by the hardware to halt the time base. When the PWM time base is in the Single Shot mode (PTMOD<1:0> = 01), an interrupt event is generated when a match with the PTPER register occurs, the PTMR register is reset to zero on the following input clock edge, and the PTEN bit is cleared. The postscaler selection bits have no effect in this mode of the timer.
The PWM time base can be configured for four different modes of operation: * * * * Free Running mode Single Shot mode Continuous Up/Down Count mode Continuous Up/Down Count mode with interrupts for double updates
15.1.3
CONTINUOUS UP/DOWN COUNTING MODES
These four modes are selected by the PTMOD<1:0> bits in the PTCON SFR. The Up/Down Counting modes support center aligned PWM generation. The Single Shot mode allows the PWM module to support pulse control of certain Electronically Commutative Motors (ECMs). The interrupt signals generated by the PWM time base depend on the mode selection bits (PTMOD<1:0>) and the postscaler bits (PTOPS<3:0>) in the PTCON SFR.
In the Continuous Up/Down Counting modes, the PWM time base counts upwards until the value in the PTPER register is matched. The timer will begin counting downwards on the following input clock edge. The PTDIR bit in the PTCON SFR is read only and indicates the counting direction The PTDIR bit is set when the timer counts downwards. In the Up/Down Counting mode (PTMOD<1:0> = 10), an interrupt event is generated each time the value of the PTMR register becomes zero and the PWM time base begins to count upwards. The postscaler selection bits may be used in this mode of the timer to reduce the frequency of the interrupt events.

15.1.4 DOUBLE UPDATE MODE
In the Double Update mode (PTMOD<1:0> = 11), an interrupt event is generated each time the PTMR register is equal to zero, as well as each time a period match occurs. The postscaler selection bits have no effect in this mode of the timer. The Double Update mode provides two additional functions to the user. First, the control loop bandwidth is doubled because the PWM duty cycles can be updated, twice per period. Second, asymmetrical center-aligned PWM waveforms can be generated, which are useful for minimizing output waveform distortion in certain motor control applications. Note: Programming a value of 0x0001 in the period register could generate a continuous interrupt pulse, and hence, must be avoided. The PWM period Equation 15-1: can be determined using
EQUATION 15-1:
TPWM =
PWM PERIOD
TCY * (PTPER + 1) (PTMR Prescale Value)
If the PWM time base is configured for one of the Up/ Down Count modes, the PWM period will be twice the value provided by Equation 15-1. The maximum resolution (in bits) for a given device oscillator and PWM frequency can be determined using Equation 15-2:
EQUATION 15-2:
Resolution =
PWM RESOLUTION
log (2 * TPWM / TCY) log (2)
15.1.5
PWM TIME BASE PRESCALER
The input clock to PTMR (FOSC/4), has prescaler options of 1:1, 1:4, 1:16, or 1:64, selected by control bits PTCKPS<1:0> in the PTCON SFR. The prescaler counter is cleared when any of the following occurs: * a write to the PTMR register * a write to the PTCON register * any device Reset The PTMR register is not cleared when PTCON is written.
15.3
Edge Aligned PWM
15.1.6
PWM TIME BASE POSTSCALER
The match output of PTMR can optionally be postscaled through a 4-bit postscaler (which gives a 1:1 to 1:16 scaling). The postscaler counter is cleared when any of the following occurs: * a write to the PTMR register * a write to the PTCON register * any device Reset The PTMR register is not cleared when PTCON is written.
Edge aligned PWM signals are produced by the module when the PWM time base is in the Free Running or Single Shot mode. For edge aligned PWM outputs, the output has a period specified by the value in PTPER and a duty cycle specified by the appropriate duty cycle register (see Figure 15-2). The PWM output is driven active at the beginning of the period (PTMR = 0) and is driven inactive when the value in the duty cycle register matches PTMR. If the value in a particular duty cycle register is zero, then the output on the corresponding PWM pin will be inactive for the entire PWM period. In addition, the output on the PWM pin will be active for the entire PWM period if the value in the duty cycle register is greater than the value held in the PTPER register.

PTPER PTMR Value
PTPER is a 15-bit register and is used to set the counting period for the PWM time base. PTPER is a double buffered register. The PTPER buffer contents are loaded into the PTPER register at the following instants: * Free Running and Single Shot modes: When the PTMR register is reset to zero after a match with the PTPER register. * Up/Down Counting modes: When the PTMR register is zero. The value held in the PTPER buffer is automatically loaded into the PTPER register when the PWM time base is disabled (PTEN = 0). 0

15.4 Center Aligned PWM
15.5.1 DUTY CYCLE REGISTER BUFFERS
Center aligned PWM signals are produced by the module when the PWM time base is configured in an Up/ Down Counting mode (see Figure 15-3). The PWM compare output is driven to the active state when the value of the duty cycle register matches the value of PTMR and the PWM time base is counting downwards (PTDIR = 1). The PWM compare output is driven to the inactive state when the PWM time base is counting upwards (PTDIR = 0) and the value in the PTMR register matches the duty cycle value. If the value in a particular duty cycle register is zero, then the output on the corresponding PWM pin will be inactive for the entire PWM period. In addition, the output on the PWM pin will be active for the entire PWM period if the value in the duty cycle register is equal to the value held in the PTPER register. The four PWM duty cycle registers are double buffered to allow glitchless updates of the PWM outputs. For each duty cycle, there is a duty cycle register that is accessible by the user and a second duty cycle register that holds the actual compare value used in the present PWM period. For edge aligned PWM output, a new duty cycle value will be updated whenever a match with the PTPER register occurs and PTMR is reset. The contents of the duty cycle buffers are automatically loaded into the duty cycle registers when the PWM time base is disabled (PTEN = 0) and the UDIS bit is cleared in PWMCON2. When the PWM time base is in the Up/Down Counting mode, new duty cycle values are updated when the value of the PTMR register is zero and the PWM time base begins to count upwards. The contents of the duty cycle buffers are automatically loaded into the duty cycle registers when the PWM time base is disabled (PTEN = 0). When the PWM time base is in the Up/Down Counting mode with double updates, new duty cycle values are updated when the value of the PTMR register is zero, and when the value of the PTMR register matches the value in the PTPER register. The contents of the duty cycle buffers are automatically loaded into the duty cycle registers when the PWM time base is disabled (PTEN = 0).

Complementary PWM Operation

PWM Duty Cycle Comparison Units
In the Complementary mode of operation, each pair of PWM outputs is obtained by a complementary PWM signal. A dead time may be optionally inserted during device switching, when both outputs are inactive for a short period (Refer to Section 15.7). In Complementary mode, the duty cycle comparison units are assigned to the PWM outputs as follows: * * * * PDC1 register controls PWM1H/PWM1L outputs PDC2 register controls PWM2H/PWM2L outputs PDC3 register controls PWM3H/PWM3L outputs PDC4 register controls PWM4H/PWM4L outputs
There are four 16-bit special function registers (PDC1, PDC2, PDC3 and PDC4) used to specify duty cycle values for the PWM module. The value in each duty cycle register determines the amount of time that the PWM output is in the active state. The duty cycle registers are 16-bits wide. The LS bit of a duty cycle register determines whether the PWM edge occurs in the beginning. Thus, the PWM resolution is effectively doubled.
The Complementary mode is selected for each PWM I/O pin pair by clearing the appropriate PMODx bit in the PWMCON1 SFR. The PWM I/O pins are set to Complementary mode by default upon a device Reset.

DEAD TIME SELECTION BITS
Function
Dead time generation may be provided when any of the PWM I/O pin pairs are operating in the Complementary Output mode. The PWM outputs use Push-Pull drive circuits. Due to the inability of the power output devices to switch instantaneously, some amount of time must be provided between the turn off event of one PWM output in a complementary pair and the turn on event of the other transistor. The PWM module allows two different dead times to be programmed. These two dead times may be used in one of two methods described below to increase user flexibility: * The PWM output signals can be optimized for different turn off times in the high side and low side transistors in a complementary pair of transistors. The first dead time is inserted between the turn off event of the lower transistor of the complementary pair and the turn on event of the upper transistor. The second dead time is inserted between the turn off event of the upper transistor and the turn on event of the lower transistor. * The two dead times can be assigned to individual PWM I/O pin pairs. This Operating mode allows the PWM module to drive different transistor/load combinations with each complementary PWM I/O pin pair.
Selects PWM1L/PWM1H active edge dead time. Selects PWM1L/PWM1H inactive edge dead time. Selects PWM2L/PWM2H active edge dead time. Selects PWM2L/PWM2H inactive edge dead time. Selects PWM3L/PWM3H active edge dead time. Selects PWM3L/PWM3H inactive edge dead time. Selects PWM4L/PWM4H active edge dead time. Selects PWM4L/PWM4H inactive edge dead time.
15.7.3
DEAD TIME RANGES
The amount of dead time provided by each dead time unit is selected by specifying the input clock prescaler value and a 6-bit unsigned value. The amount of dead time provided by each unit may be set independently. Four input clock prescaler selections have been provided to allow a suitable range of dead times, based on the device operating frequency. The clock prescaler option may be selected independently for each of the two dead time values. The dead time clock prescaler values are selected using the DTAPS<1:0> and DTBPS<1:0> control bits in the DTCON1 SFR. One of four clock prescaler options (TCY, 2TCY, 4TCY or 8TCY) may be selected for each of the dead time values. After the prescaler values are selected, the dead time for each unit is adjusted by loading two 6-bit unsigned values into the DTCON1 SFR. The dead time unit prescalers are cleared on the following events: * On a load of the down timer due to a duty cycle comparison edge event. * On a write to the DTCON1 or DTCON2 registers. * On any device Reset. Note: The user should not modify the DTCON1 or DTCON2 values while the PWM module is operating (PTEN = 1). Unexpected results may occur.
15.7.1
DEAD TIME GENERATORS
Each complementary output pair for the PWM module has a 6-bit down counter that is used to produce the dead time insertion. As shown in Figure 15-4, each dead time unit has a rising and falling edge detector connected to the duty cycle comparison output.
15.7.2
DEAD TIME ASSIGNMENT
The DTCON2 SFR contains control bits that allow the dead times to be assigned to each of the complementary outputs. Table 15-1 summarizes the function of each dead time selection control bit.

Independent PWM Output
15.10 PWM Output Override
The PWM output override bits allow the user to manually drive the PWM I/O pins to specified logic states, independent of the duty cycle comparison units. All control bits associated with the PWM output override function are contained in the OVDCON register. The upper half of the OVDCON register contains eight bits, POVDxH<4:1> and POVDxL<4:1>, that determine which PWM I/O pins will be overridden. The lower half of the OVDCON register contains eight bits, POUTxH<4:1> and POUTxL<4:1>, that determine the state of the PWM I/O pins when a particular output is overridden via the POVD bits.
An independent PWM Output mode is required for driving certain types of loads. A particular PWM output pair is in the Independent Output mode when the corresponding PMOD bit in the PWMCON1 register is set. No dead time control is implemented between adjacent PWM I/O pins when the module is operating in the Independent mode and both I/O pins are allowed to be active simultaneously. In the Independent mode, each duty cycle generator is connected to both of the PWM I/O pins in an output pair. By using the associated duty cycle register and the appropriate bits in the OVDCON register, the user may select the following signal output options for each PWM I/O pin operating in the Independent mode: * I/O pin outputs PWM signal * I/O pin inactive * I/O pin active
15.10.1
COMPLEMENTARY OUTPUT MODE
15.9
Single Pulse PWM Operation
When a PWMxL pin is driven active via the OVDCON register, the output signal is forced to be the complement of the corresponding PWMxH pin in the pair. Dead time insertion is still performed when PWM channels are overridden manually.
The PWM module produces single pulse outputs when the PTCON control bits PTMOD<1:0> = 10. Only edge aligned outputs may be produced in the Single Pulse mode. In Single Pulse mode, the PWM I/O pin(s) are driven to the active state when the PTEN bit is set. When a match with a duty cycle register occurs, the PWM I/O pin is driven to the inactive state. When a match with the PTPER register occurs, the PTMR register is cleared, all active PWM I/O pins are driven to the inactive state, the PTEN bit is cleared, and an interrupt is generated.
15.10.2
OVERRIDE SYNCHRONIZATION
If the OSYNC bit in the PWMCON2 register is set, all output overrides performed via the OVDCON register are synchronized to the PWM time base. Synchronous output overrides occur at the following times: * Edge Aligned mode, when PTMR is zero. * Center Aligned modes, when PTMR is zero and when the value of PTMR matches PTPER.

15.11 PWM Output and Polarity Control
There are three device configuration bits associated with the PWM module that provide PWM output pin control: * HPOL configuration bit * LPOL configuration bit * PWMPIN configuration bit These three bits in the FPORBOR configuration register (see Section 21) work in conjunction with the four PWM Enable bits (PWMEN<4:1>) located in the PWMCON1 SFR. The configuration bits and PWM Enable bits ensure that the PWM pins are in the correct states after a device Reset occurs. The PWMPIN configuration fuse allows the PWM module outputs to be optionally enabled on a device Reset. If PWMPIN = 0, the PWM outputs will be driven to their inactive states at Reset. If PWMPIN = 1 (default), the PWM outputs will be tri-stated. The HPOL bit specifies the polarity for the PWMxH outputs, whereas the LPOL bit specifies the polarity for the PWMxL outputs.
15.12.2
FAULT STATES
The FLTACON and FLTBCON special function registers have 8 bits each that determine the state of each PWM I/O pin when it is overridden by a FAULT input. When these bits are cleared, the PWM I/O pin is driven to the inactive state. If the bit is set, the PWM I/O pin will be driven to the active state. The active and inactive states are referenced to the polarity defined for each PWM I/O pin (HPOL and LPOL polarity control bits). A special case exists when a PWM module I/O pair is in the Complementary mode and both pins are programmed to be active on a FAULT condition. The PWMxH pin always has priority in the Complementary mode, so that both I/O pins cannot be driven active simultaneously.
15.12.3
FAULT PIN PRIORITY
If both FAULT input pins have been assigned to control a particular PWM I/O pin, the FAULT state programmed for the FAULT A input pin will take priority over the FAULT B input pin.
15.11.1
OUTPUT PIN CONTROL
15.12.4
FAULT INPUT MODES
The PEN<4:1>H and PEN<4:1>L control bits in the PWMCON1 SFR enable each high PWM output pin and each low PWM output pin, respectively. If a particular PWM output pin not enabled, it is treated as a general purpose I/O pin.
Each of the FAULT input pins has two modes of operation: * Latched Mode: When the FAULT pin is driven low, the PWM outputs will go to the states defined in the FLTACON/FLTBCON register. The PWM outputs will remain in this state until the FAULT pin is driven high and the corresponding interrupt flag has been cleared in software. When both of these actions have occurred, the PWM outputs will return to normal operation at the beginning of the next PWM cycle or half-cycle boundary. If the interrupt flag is cleared before the FAULT condition ends, the PWM module will wait until the FAULT pin is no longer asserted, to restore the outputs. * Cycle-by-Cycle Mode: When the FAULT input pin is driven low, the PWM outputs remain in the defined FAULT states for as long as the FAULT pin is held low. After the FAULT pin is driven high, the PWM outputs return to normal operation at the beginning of the following PWM cycle or half-cycle boundary. The Operating mode for each FAULT input pin is selected using the FLTAM and FLTBM control bits in the FLTACON and FLTBCON Special Function Registers. Each of the FAULT pins can be controlled manually in software.
15.12 PWM FAULT Pins
There are two FAULT pins (FLTA and FLTB) associated with the PWM module. When asserted, these pins can optionally drive each of the PWM I/O pins to a defined state.
15.12.1
FAULT PIN ENABLE BITS
The FLTACON and FLTBCON SFRs each have 4 control bits that determine whether a particular pair of PWM I/O pins is to be controlled by the FAULT input pin. To enable a specific PWM I/O pin pair for FAULT overrides, the corresponding bit should be set in the FLTACON or FLTBCON register. If all enable bits are cleared in the FLTACON or FLTBCON registers, then the corresponding FAULT input pin has no effect on the PWM module and the pin may be used as a general purpose interrupt or I/O pin. Note: The FAULT pin logic can operate independent of the PWM logic. If all the enable bits in the FLTACON/FLTBCON register are cleared, then the FAULT pin(s) could be used as general purpose interrupt pin(s). Each FAULT pin has an interrupt vector, Interrupt Flag bit and Interrupt Priority bits associated with it.

15.13 PWM Update Lockout
For a complex PWM application, the user may need to write up to four duty cycle registers and the time base period register, PTPER, at a given time. In some applications, it is important that all buffer registers be written before the new duty cycle and period values are loaded for use by the module. The PWM update lockout feature is enabled by setting the UDIS control bit in the PWMCON2 SFR. The UDIS bit affects all duty cycle buffer registers and the PWM time base period buffer, PTPER. No duty cycle changes or period value changes will have effect while UDIS = 1.
15.14.1
SPECIAL EVENT TRIGGER POSTSCALER
The PWM special event trigger has a postscaler that allows a 1:1 to 1:16 postscale ratio. The postscaler is configured by writing the SEVOPS<3:0> control bits in the PWMCON2 SFR. The special event output postscaler is cleared on the following events: * Any write to the SEVTCMP register * Any device Reset
15.15 PWM Operation During CPU Sleep Mode
The FAULT A and FAULT B input pins have the ability to wake the CPU from Sleep mode. The PWM module generates an interrupt if either of the FAULT pins is driven low while in Sleep.
15.14 PWM Special Event Trigger
The PWM module has a special event trigger that allows A/D conversions to be synchronized to the PWM time base. The A/D sampling and conversion time may be programmed to occur at any point within the PWM period. The special event trigger allows the user to minimize the delay between the time when A/D conversion results are acquired and the time when the duty cycle value is updated. The PWM special event trigger has an SFR named SEVTCMP, and five control bits to control its operation. The PTMR value for which a special event trigger should occur is loaded into the SEVTCMP register. When the PWM time base is in an Up/Down Counting mode, an additional control bit is required to specify the counting phase for the special event trigger. The count phase is selected using the SEVTDIR control bit in the SEVTCMP SFR. If the SEVTDIR bit is cleared, the special event trigger will occur on the upward counting cycle of the PWM time base. If the SEVTDIR bit is set, the special event trigger will occur on the downward count cycle of the PWM time base. The SEVTDIR control bit has no effect unless the PWM time base is configured for an Up/Down Counting mode.
15.16 PWM Operation During CPU Idle Mode
The PTCON SFR contains a PTSIDL control bit. This bit determines if the PWM module will continue to operate or stop when the device enters Idle mode. If PTSIDL = 0, the module will continue to operate. If PTSIDL = 1, the module will stop operation as long as the CPU remains in Idle mode.

16.0 SPITM MODULE
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
The Serial Peripheral Interface (SPI) module is a synchronous serial interface. It is useful for communicating with other peripheral devices such as EEPROMs, shift registers, display drivers and A/D converters, or other microcontrollers. It is compatible with Motorola's SPI and SIOP interfaces.
Transmit writes are also double buffered. The user writes to SPIxBUF. When the master or slave transfer is completed, the contents of the shift register (SPIxSR) is moved to the receive buffer. If any transmit data has been written to the buffer register, the contents of the transmit buffer are moved to SPIxSR. The received data is thus placed in SPIxBUF and the transmit data in SPIxSR is ready for the next transfer. Note: Both the transmit buffer (SPIxTXB) and the receive buffer (SPIxRXB) are mapped to the same register address, SPIxBUF.
16.1
Operating Function Description
In Master mode, the clock is generated by prescaling the system clock. Data is transmitted as soon as a value is written to SPIxBUF. The interrupt is generated at the middle of the transfer of the last bit. In Slave mode, data is transmitted and received as external clock pulses appear on SCK. Again, the interrupt is generated when the last bit is latched. If SSx control is enabled, then transmission and reception are enabled only when SSx = low. The SDOx output will be disabled in SSx mode with SSx high. The clock provided to the module is (FOSC/4). This clock is then prescaled by the primary (PPRE<1:0>) and the secondary (SPRE<2:0>) prescale factors. The CKE bit determines whether transmit occurs on transition from active clock state to Idle clock state, or vice versa. The CKP bit selects the Idle state (high or low) for the clock.
Each SPI module consists of a 16-bit shift register, SPIxSR (where x = 1 or 2), used for shifting data in and out, and a buffer register, SPIxBUF. A control register, SPIxCON, configures the module. Additionally, a status register, SPIxSTAT, indicates various status conditions. The serial interface consists of 4 pins: SDIx (serial data input), SDOx (serial data output), SCKx (shift clock input or output), and SSx (active low slave select). In Master mode operation, SCK is a clock output, but in Slave mode, it is a clock input. A series of eight (8) or sixteen (16) clock pulses shifts out bits from the SPIxSR to SDOx pin and simultaneously shifts in data from SDIx pin. An interrupt is generated when the transfer is complete and the corresponding Interrupt Flag bit (SPI1IF or SPI2IF) is set. This interrupt can be disabled through an Interrupt Enable bit (SPI1IE or SPI2IE). The receive operation is double buffered. When a complete byte is received, it is transferred from SPIxSR to SPIxBUF. If the receive buffer is full when new data is being transferred from SPIxSR to SPIxBUF, the module will set the SPIROV bit, indicating an overflow condition. The transfer of the data from SPIxSR to SPIxBUF will not be completed and the new data will be lost. The module will not respond to SCL transitions while SPIROV is 1, effectively disabling the module until SPIxBUF is read by user software.
16.1.1
WORD AND BYTE COMMUNICATION
A control bit, MODE16 (SPIxCON<10>), allows the module to communicate in either 16-bit or 8-bit mode. 16-bit operation is identical to 8-bit operation, except that the number of bits transmitted is 16 instead of 8. The user software must disable the module prior to changing the MODE16 bit. The SPI module is reset when the MODE16 bit is changed by the user. A basic difference between 8-bit and 16-bit operation is that the data is transmitted out of bit 7 of the SPIxSR for 8-bit operation, and data is transmitted out of bit 15 of the SPIxSR for 16-bit operation. In both modes, data is shifted into bit 0 of the SPIxSR.
16.1.2
SDOx DISABLE
A control bit, DISSDO, is provided to the SPIxCON register to allow the SDOx output to be disabled. This will allow the SPI module to be connected in an input only configuration. SDO can also be used for general purpose I/O.

16.2 Framed SPI Support 16.4
The module supports a basic framed SPI protocol in Master or Slave mode. The control bit FRMEN enables framed SPI support and causes the SSx pin to perform the frame synchronization pulse (FSYNC) function. The control bit SPIFSD determines whether the SSx pin is an input or an output (i.e., whether the module receives or generates the frame synchronization pulse). The frame pulse is an active high pulse for a single SPI clock cycle. When frame synchronization is enabled, the data transmission starts only on the subsequent transmit edge of the SPI clock.
SPI Operation During CPU Sleep Mode
During Sleep mode, the SPI module is shut-down. If the CPU enters Sleep mode while an SPI transaction is in progress, then the transmission and reception is aborted. The transmitter and receiver will stop in Sleep mode. However, register contents are not affected by entering or exiting Sleep mode.
16.5
SPI Operation During CPU Idle Mode
16.3
Slave Select Synchronization
The SSx pin allows a Synchronous Slave mode. The SPI must be configured in SPI Slave mode, with SSx pin control enabled (SSEN = 1). When the SSx pin is low, transmission and reception are enabled, and the SDOx pin is driven. When SSx pin goes high, the SDOx pin is no longer driven. Also, the SPI module is resynchronized, and all counters/control circuitry are reset. Therefore, when the SSx pin is asserted low again, transmission/reception will begin at the MS bit, even if SSx had been de-asserted in the middle of a transmit/receive.
When the device enters Idle mode, all clock sources remain functional. The SPISIDL bit (SPIxSTAT<13>) selects if the SPI module will stop or continue on Idle. If SPISIDL = 0, the module will continue to operate when the CPU enters Idle mode. If SPISIDL = 1, the module will stop when the CPU enters Idle mode.

17.0 I2C MODULE

* Serial clock synchronization for I2C port can be used as a handshake mechanism to suspend and resume serial transfer (SCLREL control). * I2C supports Multi-Master operation; detects bus collision and will arbitrate accordingly.
The Inter-Integrated Circuit (I2C) module provides complete hardware support for both Slave and MultiMaster modes of the I2C serial communication standard, with a 16-bit interface. This module offers the following key features: * I2C interface supporting both Master and Slave operation. * I2C Slave mode supports 7 and 10-bit address. * I2C Master mode supports 7 and 10-bit address. * I2C port allows bi-directional transfers between master and slaves.
17.1
Operating Function Description
The hardware fully implements all the master and slave functions of the I2C Standard and Fast mode specifications, as well as 7 and 10-bit addressing. Thus, the I2C module can operate either as a slave or a master on an I2C bus.
17.1.1
* * *
VARIOUS I2C MODES
The following types of I2C operation are supported: I2C Slave operation with 7-bit address I2C Slave operation with 10-bit address I2C Master operation with 7 or 10-bit address
See the I2C programmer's model in Figure 17-1.

A status bit, ADD10, indicates 10-bit Address mode. The I2CBRG acts as the baud rate generator reload value. In receive operations, I2CRSR and I2CRCV together form a double buffered receiver. When I2CRSR receives a complete byte, it is transferred to I2CRCV and an interrupt pulse is generated. During transmission, the I2CTRN is not double buffered. Note: Following a Restart condition in 10-bit mode, the user only needs to match the first 7-bit address.

I2C REGISTERS
I2CCON and I2CSTAT are control and status registers, respectively. The I2CCON register is readable and writable. The lower 6 bits of I2CSTAT are read only. The remaining bits of the I2CSTAT are read/write. I2CRSR is the shift register used for shifting data, whereas I2CRCV is the buffer register to which data bytes are written, or from which data bytes are read. I2CRCV is the receive buffer, as shown in Figure 16-1. I2CTRN is the transmit register to which bytes are written during a transmit operation, as shown in Figure 16-2.

17.2 I2C Module Addresses
The I2CADD register contains the Slave mode addresses. The register is a 10-bit register. If the A10M bit (I2CCON<10>) is `0', the address is interpreted by the module as a 7-bit address. When an address is received, it is compared to the 7 LS bits of the I2CADD register. If the A10M bit is 1, the address is assumed to be a 10bit address. When an address is received, it will be compared with the binary value `1 1 1 1 0 A9 A8' (where A9, A8 are two Most Significant bits of I2CADD). If that value matches, the next address will be compared with the Least Significant 8-bits of I2CADD, as specified in the 10-bit addressing protocol. If the RBF flag is set, indicating that I2CRCV is still holding data from a previous operation (RBF = 1), then ACK is not sent; however, the interrupt pulse is generated. In the case of an overflow, the contents of the I2CRSR are not loaded into the I2CRCV. Note: The I2CRCV will be loaded if the I2COV bit = 1 and the RBF flag = 0. In this case, a read of the I2CRCV was performed, but the user did not clear the state of the I2COV bit before the next receive occurred. The acknowledgement is not sent (ACK = 1) and the I2CRCV is updated.
17.4
I2C 10-bit Slave Mode Operation
17.3
I2C 7-bit Slave Mode Operation
Once enabled (I2CEN = 1), the slave module will wait for a start bit to occur (i.e., the I2C module is `Idle'). Following the detection of a start bit, 8 bits are shifted into I2CRSR and the address is compared against I2CADD. In 7-bit mode (A10M = 0), bits I2CADD<6:0> are compared against I2CRSR<7:1> and I2CRSR<0> is the R_W bit. All incoming bits are sampled on the rising edge of SCL. If an address match occurs, an acknowledgement will be sent, and the slave event interrupt flag (SI2CIF) is set on the falling edge of the ninth (ACK) bit. The address match does not affect the contents of the I2CRCV buffer or the RBF bit.
In 10-bit mode, the basic receive and transmit operations are the same as in the 7-bit mode. However, the criteria for address match is more complex. The I2C specification dictates that a slave must be addressed for a write operation, with two address bytes following a start bit. The A10M bit is a control bit that signifies that the address in I2CADD is a 10-bit address rather than a 7-bit address. The address detection protocol for the first byte of a message address is identical for 7-bit and 10-bit messages, but the bits being compared are different. I2CADD holds the entire 10-bit address. Upon receiving an address following a start bit, I2CRSR <7:3> is compared against a literal `11110' (the default 10-bit address) and I2CRSR<2:1> are compared against I2CADD<9:8>. If a match occurs and if R_W = 0, the interrupt pulse is sent. The ADD10 bit will be cleared to indicate a partial address match. If a match fails or R_W = 1, the ADD10 bit is cleared and the module returns to the Idle state. The low byte of the address is then received and compared with I2CADD<7:0>. If an address match occurs, the interrupt pulse is generated and the ADD10 bit is set, indicating a complete 10-bit address match. If an address match did not occur, the ADD10 bit is cleared and the module returns to the Idle state.
17.3.1
SLAVE TRANSMISSION
If the R_W bit received is a '1', then the serial port will go into Transmit mode. It will send ACK on the ninth bit and then hold SCL to '0' until the CPU responds by writing to I2CTRN. SCL is released by setting the SCLREL bit, and 8 bits of data are shifted out. Data bits are shifted out on the falling edge of SCL, such that SDA is valid during SCL high (see timing diagram). The interrupt pulse is sent on the falling edge of the ninth clock pulse, regardless of the status of the ACK received from the master.
17.3.2
SLAVE RECEPTION
If the R_W bit received is a '0' during an address match, then Receive mode is initiated. Incoming bits are sampled on the rising edge of SCL. After 8 bits are received, if I2CRCV is not full or I2COV is not set, I2CRSR is transferred to I2CRCV. ACK is sent on the ninth clock.
17.4.1
10-BIT MODE SLAVE TRANSMISSION
Once a slave is addressed in this fashion, with the full 10-bit address (we will refer to this state as "PRIOR_ADDR_MATCH"), the master can begin sending data bytes for a slave reception operation.
17.4.2
10-BIT MODE SLAVE RECEPTION
Once addressed, the master can generate a Repeated Start, reset the high byte of the address and set the R_W bit without generating a Stop bit, thus initiating a slave transmit operation.

17.5 Automatic Clock Stretch
In the slave modes, the module can synchronize buffer reads and write to the master device by clock stretching. Note 1: If the user reads the contents of the I2CRCV, clearing the RBF bit before the falling edge of the ninth clock, the SCLREL bit will not be cleared and clock stretching will not occur. 2: The SCLREL bit can be set in software, regardless of the state of the RBF bit. The user should be careful to clear the RBF bit in the ISR before the next receive sequence in order to prevent an overflow condition.
17.5.1
TRANSMIT CLOCK STRETCHING
Both 10-bit and 7-bit transmit modes implement clock stretching by asserting the SCLREL bit after the falling edge of the ninth clock if the TBF bit is cleared, indicating the buffer is empty. In slave transmit modes, clock stretching is always performed, irrespective of the STREN bit. Clock synchronization takes place following the ninth clock of the transmit sequence. If the device samples an ACK on the falling edge of the ninth clock, and if the TBF bit is still clear, then the SCLREL bit is automatically cleared. The SCLREL being cleared to `0' will assert the SCL line low. The user's ISR must set the SCLREL bit before transmission is allowed to continue. By holding the SCL line low, the user has time to service the ISR and load the contents of the I2CTRN before the master device can initiate another transmit sequence. Note 1: If the user loads the contents of I2CTRN, setting the TBF bit before the falling edge of the ninth clock, the SCLREL bit will not be cleared and clock stretching will not occur. 2: The SCLREL bit can be set in software, regardless of the state of the TBF bit.
17.5.4
CLOCK STRETCHING DURING 10-BIT ADDRESSING (STREN = 1)
Clock stretching takes place automatically during the addressing sequence. Because this module has a register for the entire address, it is not necessary for the protocol to wait for the address to be updated. After the address phase is complete, clock stretching will occur on each data receive or transmit sequence as was described earlier.
17.6
Software Controlled Clock Stretching (STREN = 1)
17.5.2
RECEIVE CLOCK STRETCHING
The STREN bit in the I2CCON register can be used to enable clock stretching in Slave Receive mode. When the STREN bit is set, the SCL pin will be held low at the end of each data receive sequence.
When the STREN bit is `1', the SCLREL bit may be cleared by software to allow software to control the clock stretching. The logic will synchronize writes to the SCLREL bit with the SCL clock. Clearing the SCLREL bit will not assert the SCL output until the module detects a falling edge on the SCL output and SCL is sampled low. If the SCLREL bit is cleared by the user while the SCL line has been sampled low, the SCL output will be asserted (held low). The SCL output will remain low until the SCLREL bit is set, and all other devices on the I2C bus have de-asserted SCL. This ensures that a write to the SCLREL bit will not violate the minimum high time requirement for SCL. If the STREN bit is `0', a software write to the SCLREL bit will be disregarded and have no effect on the SCLREL bit.
17.5.3
CLOCK STRETCHING DURING 7-BIT ADDRESSING (STREN = 1)
When the STREN bit is set in Slave Receive mode, the SCL line is held low when the buffer register is full. The method for stretching the SCL output is the same for both 7 and 10-bit addressing modes. Clock stretching takes place following the ninth clock of the receive sequence. On the falling edge of the ninth clock at the end of the ACK sequence, if the RBF bit is set, the SCLREL bit is automatically cleared, forcing the SCL output to be held low. The user's ISR must set the SCLREL bit before reception is allowed to continue. By holding the SCL line low, the user has time to service the ISR and read the contents of the I2CRCV before the master device can initiate another receive sequence. This will prevent buffer overruns from occurring.
17.7
Interrupts
The I2C module generates two interrupt flags, MI2CIF (I2C Master Interrupt Flag) and SI2CIF (I2C Slave Interrupt Flag). The MI2CIF interrupt flag is activated on completion of a master message event. The SI2CIF interrupt flag is activated on detection of a message directed to the slave.
17.8
I2C
Slope Control
The standard requires slope control on the SDA and SCL signals for Fast Mode (400 kHz). The control bit, DISSLW, enables the user to disable slew rate control, if desired. It is necessary to disable the slew rate control for 1 MHz mode.

17.9 IPMI Support
The control bit IPMIEN enables the module to support Intelligent Peripheral Management Interface (IPMI). When this bit is set, the module accepts and acts upon all addresses. transmitted, an ACK bit is received. Start and Stop conditions are output to indicate the beginning and the end of a serial transfer. In Master Receive mode, the first byte transmitted contains the slave address of the transmitting device (7 bits) and the data direction bit. In this case, the data direction bit (R_W) is logic 1. Thus, the first byte transmitted is a 7-bit slave address, followed by a `1' to indicate receive bit. Serial data is received via SDA, while SCL outputs the serial clock. Serial data is received 8 bits at a time. After each byte is received, an ACK bit is transmitted. Start and Stop conditions indicate the beginning and end of transmission.
17.10 General Call Address Support
The general call address can address all devices. When this address is used, all devices should, in theory, respond with an acknowledgement. The general call address is one of eight addresses reserved for specific purposes by the I2C protocol. It consists of all 0's with R_W = 0. The general call address is recognized when the General Call Enable (GCEN) bit is set (I2CCON<15> = 1). Following a start bit detection, 8 bits are shifted into I2CRSR and the address is compared with I2CADD, and is also compared with the general call address which is fixed in hardware. If a general call address match occurs, the I2CRSR is transferred to the I2CRCV after the eighth clock, the RBF flag is set, and on the falling edge of the ninth bit (ACK bit), the master event interrupt flag (MI2CIF) is set. When the interrupt is serviced, the source for the interrupt can be checked by reading the contents of the I2CRCV to determine if the address was device specific, or a general call address.
17.12.1
I2C MASTER TRANSMISSION
Transmission of a data byte, a 7-bit address, or the second half of a 10-bit address is accomplished by simply writing a value to I2CTRN register. The user should only write to I2CTRN when the module is in a WAIT state. This action will set the buffer full flag (TBF) and allow the baud rate generator to begin counting and start the next transmission. Each bit of address/data will be shifted out onto the SDA pin after the falling edge of SCL is asserted. The Transmit Status Flag, TRSTAT (I2CSTAT<14>), indicates that a master transmit is in progress.
17.12.2
I2C MASTER RECEPTION
17.11 I2C Master Support
As a Master device, six operations are supported. * Assert a Start condition on SDA and SCL. * Assert a Restart condition on SDA and SCL. * Write to the I2CTRN register initiating transmission of data/address. * Generate a Stop condition on SDA and SCL. * Configure the I2C port to receive data. * Generate an ACK condition at the end of a received byte of data.
Master mode reception is enabled by programming the receive enable (RCEN) bit (I2CCON<11>). The I2C module must be Idle before the RCEN bit is set, otherwise the RCEN bit will be disregarded. The baud rate generator begins counting, and on each rollover, the state of the SCL pin toggles, and data is shifted in to the I2CRSR on the rising edge of each clock.
17.12.3
I 2C
BAUD RATE GENERATOR
In Master mode, the reload value for the BRG is located in the I2CBRG register. When the BRG is loaded with this value, the BRG counts down to 0 and stops until another reload has taken place. If clock arbitration is taking place, for instance, the BRG is reloaded when the SCL pin is sampled high. As per the I2C standard, FSCK may be 100 kHz or 400 kHz. However, the user can specify any baud rate up to 1 MHz. I2CBRG values of 0 or 1 are illegal.
17.12 I2C Master Operation
The master device generates all of the serial clock pulses and the Start and Stop conditions. A transfer is ended with a Stop condition or with a Repeated Start condition. Since the Repeated Start condition is also the beginning of the next serial transfer, the I2C bus will not be released. In Master Transmitter mode, serial data is output through SDA, while SCL outputs the serial clock. The first byte transmitted contains the slave address of the receiving device (7 bits) and the data direction bit. In this case, the data direction bit (R_W) is logic 0. Serial data is transmitted 8 bits at a time. After each byte is

17.12.4 CLOCK ARBITRATION
Clock arbitration occurs when the master de-asserts the SCL pin (SCL allowed to float high) during any receive, transmit, or Restart/Stop condition. When the SCL pin is allowed to float high, the baud rate generator (BRG) is suspended from counting until the SCL pin is actually sampled high. When the SCL pin is sampled high, the baud rate generator is reloaded with the contents of I2CBRG and begins counting. This ensures that the SCL high time will always be at least one BRG rollover count in the event that the clock is held low by an external device. The Master will continue to monitor the SDA and SCL pins, and if a Stop condition occurs, the MI2CIF bit will be set. A write to the I2CTRN will start the transmission of data at the first data bit, regardless of where the transmitter left off when bus collision occurred. In a Multi-Master environment, the interrupt generation on the detection of Start and Stop conditions allows the determination of when the bus is free. Control of the I2C bus can be taken when the P bit is set in the I2CSTAT register, or the bus is Idle and the S and P bits are cleared.
17.12.5
MULTI-MASTER COMMUNICATION, BUS COLLISION AND BUS ARBITRATION
17.13 I2C Module Operation During CPU Sleep and Idle Modes
17.13.1 I2C OPERATION DURING CPU SLEEP MODE
Multi-Master operation support is achieved by bus arbitration. When the master outputs address/data bits onto the SDA pin, arbitration takes place when the master outputs a 1 on SDA, by letting SDA float high while another master asserts a 0. When the SCL pin floats high, data should be stable. If the expected data on SDA is a 1 and the data sampled on the SDA pin = 0, then a bus collision has taken place. The master will set the MI2CIF pulse and reset the master portion of the I2C port to its Idle state. If a transmit was in progress when the bus collision occurred, the transmission is halted, the TBF flag is cleared, the SDA and SCL lines are de-asserted, and a value can now be written to I2CTRN. When the user services the I2C master event Interrupt Service Routine, if the I2C bus is free (i.e., the P bit is set) the user can resume communication by asserting a Start condition. If a Start, Restart, Stop or Acknowledge condition was in progress when the bus collision occurred, the condition is aborted, the SDA and SCL lines are de-asserted, and the respective control bits in the I2CCON register are cleared to 0. When the user services the bus collision Interrupt Service Routine, and if the I2C bus is free, the user can resume communication by asserting a Start condition.
When the device enters Sleep mode, all clock sources to the module are shutdown and stay at logic `0'. If Sleep occurs in the middle of a transmission, and the state machine is partially into a transmission as the clocks stop, then the transmission is aborted. Similarly, if Sleep occurs in the middle of a reception, then the reception is aborted.
17.13.2
I2C OPERATION DURING CPU IDLE MODE
For the I2C, the I2CSIDL bit selects if the module will stop on Idle or continue on Idle. If I2CSIDL = 0, the module will continue operation on assertion of the Idle mode. If I2CSIDL = 1, the module will stop on Idle.

Enabling and Setting Up UART
ENABLING THE UART
18.3
18.3.1
Transmitting Data
TRANSMITTING IN 8-BIT DATA MODE
The UART module is enabled by setting the UARTEN bit in the UxMODE register (where x = 1 or 2). Once enabled, the UxTX and UxRX pins are configured as an output and an input respectively, overriding the TRIS and LATCH Register bit settings for the corresponding I/O port pins. The UxTX pin is at logic `1' when no transmission is taking place.
The following steps must be performed in order to transmit 8-bit data: 1. Set up the UART: First, the data length, parity and number of stop bits must be selected. Then, the Transmit and Receive Interrupt enable and priority bits are setup in the UxMODE and UxSTA registers. Also, the appropriate baud rate value must be written to the UxBRG register. Enable the UART by setting the UARTEN bit (UxMODE<15>). Set the UTXEN bit (UxSTA<10>), thereby enabling a transmission. The UTXEN bit must be set after the UARTEN bit is set to enable UART transmissions. Write the byte to be transmitted to the lower byte of UxTXREG. The value will be transferred to the Transmit Shift register (UxTSR) immediately and the serial bit stream will start shifting out during the next rising edge of the baud clock. Alternatively, the data byte may be written while UTXEN = 0, following which, the user may set UTXEN. This will cause the serial bit stream to begin immediately because the baud clock will start from a cleared state. A Transmit interrupt will be generated depending on the value of the interrupt control bit UTXISEL (UxSTA<15>). Note:
18.2.2
DISABLING THE UART
2. 3.
The UART module is disabled by clearing the UARTEN bit in the UxMODE register. This is the default state after any Reset. If the UART is disabled, all I/O pins operate as port pins under the control of the latch and TRIS bits of the corresponding port pins. Disabling the UART module resets the buffers to empty states. Any data characters in the buffers are lost, and the baud rate counter is reset. All error and status flags associated with the UART module are reset when the module is disabled. The URXDA, OERR, FERR, PERR, UTXEN, UTXBRK and UTXBF bits are cleared, whereas RIDLE and TRMT are set. Other control bits, including ADDEN, URXISEL<1:0>, UTXISEL, as well as the UxMODE and UxBRG registers, are not affected. Clearing the UARTEN bit while the UART is active will abort all pending transmissions and receptions and reset the module as defined above. Re-enabling the UART will restart the UART in the same configuration.
4.
5.
18.2.3
SETTING UP DATA, PARITY AND STOP BIT SELECTIONS
Control bits PDSEL<1:0> in the UxMODE register are used to select the data length and parity used in the transmission. The data length may either be 8-bits with even, odd or no parity, or 9-bits with no parity. The STSEL bit determines whether one or two stop bits will be used during data transmission. The default (Power-on) setting of the UART is 8 bits, no parity, 1 stop bit (typically represented as 8, N, 1).
18.3.2
TRANSMITTING IN 9-BIT DATA MODE
The sequence of steps involved in the transmission of 9-bit data is similar to 8-bit transmission, except that a 16-bit data word (of which the upper 7 bits are always clear) must be written to the UxTXREG register.
18.3.3
TRANSMIT BUFFER (UXTXB)
The transmit buffer is 9-bits wide and 4 characters deep. Including the Transmit Shift Register (UxTSR), the user effectively has a 5-deep FIFO (First In First Out) buffer. The UTXBF Status bit (UxSTA<9>) indicates whether the transmit buffer is full. If a user attempts to write to a full buffer, the new data will not be accepted into the FIFO, and no data shift will occur within the buffer. This enables recovery from a buffer overrun condition. The FIFO is reset during any device Reset, but is not affected when the device enters or wakes up from a Power Saving mode.

18.3.4 TRANSMIT INTERRUPT 18.4.2 RECEIVE BUFFER (UXRXB)
The transmit interrupt flag (U1TXIF or U2TXIF) is located in the corresponding interrupt flag register. The transmitter generates an edge to set the UxTXIF bit. The condition for generating the interrupt depends on UTXISEL control bit: a) If UTXISEL = 0, an interrupt is generated when a word is transferred from the Transmit buffer to the Transmit Shift register (UxTSR). This implies that the transmit buffer has at least one empty word. If UTXISEL = 1, an interrupt is generated when a word is transferred from the Transmit buffer to the Transmit Shift register (UxTSR) and the Transmit buffer is empty. The receive buffer is 4 words deep. Including the Receive Shift register (UxRSR), the user effectively has a 5-word deep FIFO buffer. URXDA (UxSTA<0>) = 1 indicates that the receive buffer has data available. URXDA = 0 implies that the buffer is empty. If a user attempts to read an empty buffer, the old values in the buffer will be read and no data shift will occur within the FIFO. The FIFO is reset during any device Reset. It is not affected when the device enters or wakes up from a Power Saving mode.
b)
18.4.3
RECEIVE INTERRUPT
Switching between the two interrupt modes during operation is possible and sometimes offers more flexibility.
18.3.5
TRANSMIT BREAK
The receive interrupt flag (U1RXIF or U2RXIF) can be read from the corresponding interrupt flag register. The interrupt flag is set by an edge generated by the receiver. The condition for setting the receive interrupt flag depends on the settings specified by the URXISEL<1:0> (UxSTA<7:6>) control bits. a) If URXISEL<1:0> = 00 or 01, an interrupt is generated every time a data word is transferred from the Receive Shift Register (UxRSR) to the Receive Buffer. There may be one or more characters in the receive buffer. If URXISEL<1:0> = 10, an interrupt is generated when a word is transferred from the Receive Shift Register (UxRSR) to the Receive Buffer, which, as a result of the transfer, contains 3 characters. If URXISEL<1:0> = 11, an interrupt is set when a word is transferred from the Receive Shift Register (UxRSR) to the Receive Buffer, which, as a result of the transfer, contains 4 characters (i.e., becomes full).
Setting the UTXBRK bit (UxSTA<11>) will cause the UxTX line to be driven to logic `0'. The UTXBRK bit overrides all transmission activity. Therefore, the user should generally wait for the transmitter to be Idle before setting UTXBRK. To send a break character, the UTXBRK bit must be set by software and must remain set for a minimum of 13 baud clock cycles. The UTXBRK bit is then cleared by software to generate stop bits. The user must wait for a duration of at least one or two baud clock cycles in order to ensure a valid stop bit(s) before reloading the UxTXB or starting other transmitter activity. Transmission of a break character does not generate a transmit interrupt.
b)
c)
18.4
18.4.1
Receiving Data
RECEIVING IN 8-BIT OR 9-BIT DATA MODE
Switching between the Interrupt modes during operation is possible, though generally not advisable during normal operation.
The following steps must be performed while receiving 8-bit or 9-bit data: 1. 2. 3. Set up the UART (see Section 18.3.1). Enable the UART (see Section 18.3.1). A receive interrupt will be generated when one or more data words have been received, depending on the receive interrupt settings specified by the URXISEL bits (UxSTA<7:6>). Read the OERR bit to determine if an overrun error has occurred. The OERR bit must be reset in software. Read the received data from UxRXREG. The act of reading UxRXREG will move the next word to the top of the receive FIFO, and the PERR and FERR values will be updated.
18.5
18.5.1
Reception Error Handling
RECEIVE BUFFER OVERRUN ERROR (OERR BIT)
The OERR bit (UxSTA<1>) is set if all of the following conditions occur: a) b) c) The receive buffer is full. The receive shift register is full, but unable to transfer the character to the receive buffer. The stop bit of the character in the UxRSR is detected, indicating that the UxRSR needs to transfer the character to the buffer.
4.
5.
Once OERR is set, no further data is shifted in UxRSR (until the OERR bit is cleared in software or a Reset occurs). The data held in UxRSR and UxRXREG remains valid.

18.5.2 FRAMING ERROR (FERR)
18.6
Address Detect Mode
The FERR bit (UxSTA<2>) is set if a `0' is detected instead of a stop bit. If two stop bits are selected, both stop bits must be `1', otherwise FERR will be set. The read only FERR bit is buffered along with the received data. It is cleared on any Reset.
18.5.3
PARITY ERROR (PERR)
The PERR bit (UxSTA<3>) is set if the parity of the received word is incorrect. This error bit is applicable only if a Parity mode (odd or even) is selected. The read only PERR bit is buffered along with the received data bytes. It is cleared on any Reset.
Setting the ADDEN bit (UxSTA<5>) enables this special mode, in which a 9th bit (URX8) value of `1' identifies the received word as an address rather than data. This mode is only applicable for 9-bit data communication. The URXISEL control bit does not have any impact on interrupt generation in this mode, since an interrupt (if enabled) will be generated every time the received word has the 9th bit set.
18.7
Loopback Mode
18.5.4
IDLE STATUS
When the receiver is active (i.e., between the initial detection of the start bit and the completion of the stop bit), the RIDLE bit (UxSTA<4>) is `0'. Between the completion of the stop bit and detection of the next start bit, the RIDLE bit is `1', indicating that the UART is Idle.
Setting the LPBACK bit enables this special mode in which the UxTX pin is internally connected to the UxRX pin. When configured for the Loopback mode, the UxRX pin is disconnected from the internal UART receive logic. However, the UxTX pin still functions as in a normal operation. To select this mode: a) b) c) Configure UART for desired mode of operation. Set LPBACK = 1 to enable Loopback mode. Enable transmission as defined in Section 18.3.
18.5.5
RECEIVE BREAK
The receiver will count and expect a certain number of bit times based on the values programmed in the PDSEL (UxMODE<2:1>) and STSEL (UxMODE<0>) bits. If the break is longer than 13 bit times, the reception is considered complete after the number of bit times specified by PDSEL and STSEL. The URXDA bit is set, FERR is set, zeros are loaded into the receive FIFO, interrupts are generated, if appropriate and the RIDLE bit is set. When the module receives a long break signal and the receiver has detected the start bit, the data bits and the invalid stop bit (which sets the FERR), the receiver must wait for a valid stop bit before looking for the next start bit. It cannot assume that the break condition on the line is the next start bit. Break is regarded as a character containing all 0's, with the FERR bit set. The break character is loaded into the buffer. No further reception can occur until a stop bit is received. Note that RIDLE goes high when the stop bit has not been received yet.
18.8
Baud Rate Generator
The UART has a 16-bit baud rate generator to allow maximum flexibility in baud rate generation. The baud rate generator register (UxBRG) is readable and writable. The baud rate is computed as follows: BRG = 16-bit value held in UxBRG register (0 through 65535) FCY = Instruction Clock Rate (1/TCY) The Baud Rate is given by Equation 18-1.
EQUATION 18-1:
BAUD RATE
Baud Rate = FCY / (16*(BRG+1)) Therefore, maximum baud rate possible is FCY /16 (if BRG = 0), and the minimum baud rate possible is FCY / (16* 65536). With a full 16-bit baud rate generator, at 30 MIPs operation, the minimum baud rate achievable is 28.5 bps.

18.9 Auto Baud Support
18.10.2
To allow the system to determine baud rates of received characters, the input can be optionally linked to a selected capture input. To enable this mode, the user must program the input capture module to detect the falling and rising edges of the start bit.
UART OPERATION DURING CPU IDLE MODE
For the UART, the USIDL bit selects if the module will stop operation when the device enters Idle mode, or whether the module will continue on Idle. If USIDL = 0, the module will continue operation during Idle mode. If USIDL = 1, the module will stop on Idle.
18.10 UART Operation During CPU Sleep and Idle Modes
18.10.1 UART OPERATION DURING CPU SLEEP MODE
When the device enters Sleep mode, all clock sources to the module are shutdown and stay at logic `0'. If entry into Sleep mode occurs while a transmission is in progress, then the transmission is aborted. The UxTX pin is driven to logic `1'. Similarly, if entry into Sleep mode occurs while a reception is in progress, then the reception is aborted. The UxSTA, UxMODE, transmit and receive registers and buffers, and the UxBRG register are not affected by Sleep mode. If the Wake bit (UxMODE<7>) is set before the device enters Sleep mode, then a falling edge on the UxRX pin will generate a receive interrupt. The Receive Interrupt Select Mode bit (URXISEL) has no effect for this function. If the receive interrupt is enabled, then this will wake-up the device from Sleep. The UARTEN bit must be set in order to generate a wake-up interrupt.

19.0 CAN MODULE
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
19.1
Overview
The CAN bus module consists of a protocol engine, and message buffering/control. The CAN protocol engine handles all functions for receiving and transmitting messages on the CAN bus. Messages are transmitted by first loading the appropriate data registers. Status and errors can be checked by reading the appropriate registers. Any message detected on the CAN bus is checked for errors and then matched against filters to see if it should be received and stored in one of the receive registers.
The Controller Area Network (CAN) module is a serial interface, useful for communicating with other CAN modules or microcontroller devices. This interface/ protocol was designed to allow communications within noisy environments. The dsPIC30F6010 has 2 CAN modules. The CAN module is a communication controller implementing the CAN 2.0 A/B protocol, as defined in the BOSCH specification. The module will support CAN 1.2, CAN 2.0A, CAN2.0B Passive and CAN 2.0B Active versions of the protocol. The module implementation is a full CAN system. The CAN specification is not covered within this data sheet. The reader may refer to the BOSCH CAN specification for further details. The module features are as follows: * Implementation of the CAN protocol CAN 1.2, CAN 2.0A and CAN 2.0B * Standard and extended data frames * 0-8 bytes data length * Programmable bit rate up to 1 Mbit/sec * Support for remote frames * Double buffered receiver with two prioritized received message storage buffers (each buffer may contain up to 8 bytes of data) * 6 full (standard/extended identifier) acceptance filters, 2 associated with the high priority receive buffer, and 4 associated with the low priority receive buffer * 2 full acceptance filter masks, one each associated with the high and low priority receive buffers * Three transmit buffers with application specified prioritization and abort capability (each buffer may contain up to 8 bytes of data) * Programmable wake-up functionality with integrated low pass filter * Programmable Loopback mode supports self-test operation * Signaling via interrupt capabilities for all CAN receiver and transmitter error states * Programmable clock source * Programmable link to timer module for time-stamping and network synchronization * Low power Sleep and Idle mode
19.2
Frame Types
The CAN module transmits various types of frames, which include data messages or remote transmission Requests initiated by the user as other frames that are automatically generated for control purposes. The following frame types are supported: * Standard Data Frame A Standard Data Frame is generated by a node when the node wishes to transmit data. It includes a 11-bit Standard Identifier (SID) but not an 18-bit Extended Identifier (EID). * Extended Data Frame An Extended Data Frame is similar to a Standard Data Frame, but includes an Extended Identifier as well. * Remote Frame It is possible for a destination node to request the data from the source. For this purpose, the destination node sends a Remote Frame with an identifier that matches the identifier of the required Data Frame. The appropriate data source node will then send a Data Frame as a response to this Remote request. * Error Frame An Error Frame is generated by any node that detects a bus error. An error frame consists of 2 fields: an Error Flag field and an Error Delimiter field. * Overload Frame An Overload Frame can be generated by a node as a result of 2 conditions. First, the node detects a dominant bit during lnterframe Space which is an illegal condition. Second, due to internal conditions, the node is not yet able to start reception of the next message. A node may generate a maximum of 2 sequential Overload Frames to delay the start of the next message. * Interframe Space Interframe Space separates a proceeding frame (of whatever type) from a following Data or Remote Frame.

19.3 Modes of Operation
The CAN Module can operate in one of several operation modes selected by the user. These modes include: * * * * * * Initialization Mode Disable Mode Normal Operation Mode Listen Only Mode Loop Back Mode Error Recognition Mode The module can be programmed to apply a low-pass filter function to the CiRX input line while the module or the CPU is in Sleep mode. The WAKFIL bit (CiCFG2<14>) enables or disables the filter. Note: Typically, if the CAN module is allowed to transmit in a particular mode of operation and a transmission is requested immediately after the CAN module has been placed in that mode of operation, the module waits for 11 consecutive recessive bits on the bus before starting transmission. If the user switches to Disable mode within this 11-bit period, then this transmission is aborted and the corresponding TXABT bit is set and TXREQ bit is cleared.
Modes are requested by setting the REQOP<2:0> bits (CiCTRL<10:8>), except the Error Recognition mode which is requested through the RXM<1:0> bits (CiRXnCON<6:5>, where n = 0 or 1 represents a particular receive buffer). Entry into a mode is acknowledged by monitoring the OPMODE<2:0> bits (CiCTRL<7:5>). The module will not change the mode and the OPMODE bits until a change in mode is acceptable, generally during bus idle time which is defined as at least 11 consecutive recessive bits.
19.3.3
NORMAL OPERATION MODE
19.3.1
INITIALIZATION MODE
Normal Operating mode is selected when REQOP<2:0> = `000'. In this mode, the module is activated, the I/O pins will assume the CAN bus functions. The module will transmit and receive CAN bus messages via the CxTX and CxRX pins.
In the Initialization mode, the module will not transmit or receive. The error counters are cleared and the interrupt flags remain unchanged. The programmer will have access to configuration registers that are access restricted in other modes. The module will protect the user from accidentally violating the CAN protocol through programming errors. All registers which control the configuration of the module can not be modified while the module is on-line. The CAN module will not be allowed to enter the Configuration mode while a transmission is taking place. The Configuration mode serves as a lock to protect the following registers. * * * * * All Module Control Registers Baud Rate and interrupt Configuration Registers Bus Timing Registers Identifier Acceptance Filter Registers Identifier Acceptance Mask Registers
19.3.4
LISTEN ONLY MODE
If the Listen Only mode is activated, the module on the CAN bus is passive. The transmitter buffers revert to the Port I/O function. The receive pins remain inputs. For the receiver, no error flags or acknowledge signals are sent. The error counters are deactivated in this state. The Listen Only mode can be used for detecting the baud rate on the CAN bus. To use this, it is necessary that there are at least two further nodes that communicate with each other.
19.3.5
ERROR RECOGNITION MODE
19.3.2
DISABLE MODE
The module can be set to ignore all errors and receive any message. The Error Recognition mode is activated by setting the RXM<1:0> bits (CiRXnCON<6:5>) registers to `11'. In this mode the data which is in the message assembly buffer until the time an error occurred, is copied in the receive buffer and can be read via the CPU interface.
In Disable mode, the module will not transmit or receive. The module has the ability to set the WAKIF bit due to bus activity, however any pending interrupts will remain and the error counters will retain their value. If the REQOP<2:0> bits (CiCTRL<10:8>) = `001', the module will enter the Module Disable mode. If the module is active, the module will wait for 11 recessive bits on the CAN bus, detect that condition as an idle bus, then accept the module disable command. When the OPMODE<2:0> bits (CiCTRL<7:5>) = `001', that indicates whether the module successfully went into Module Disable mode. The I/O pins will revert to normal I/O function when the module is in the Module Disable mode.
19.3.6
LOOP BACK MODE
If the Loopback mode is activated, the module will connect the internal transmit signal to the internal receive signal at the module boundary. The transmit and receive pins revert to their Port I/O function.

19.4.1
Message Reception
RECEIVE BUFFERS
19.4.4
RECEIVE OVERRUN
The CAN bus module has 3 receive buffers. However, one of the receive buffers is always committed to monitoring the bus for incoming messages. This buffer is called the message assembly buffer (MAB). So there are 2 receive buffers visible, RXB0 and RXB1, that can essentially instantaneously receive a complete message from the protocol engine. All messages are assembled by the MAB, and are transferred to the RXBn buffers only if the acceptance filter criterion are met. When a message is received, the RXnIF flag (CiINTF<0> or CiINRF<1>) will be set. This bit can only be set by the module when a message is received. The bit is cleared by the CPU when it has completed processing the message in the buffer. If the RXnIE bit (CiINTE<0> or CiINTE<1>) is set, an interrupt will be generated when a message is received. RXF0 and RXF1 filters with RXM0 mask are associated with RXB0. The filters RXF2, RXF3, RXF4, and RXF5 and the mask RXM1 are associated with RXB1.
An overrun condition occurs when the Message Assembly Buffer (MAB) has assembled a valid received message, the message is accepted through the acceptance filters, and when the receive buffer associated with the filter has not been designated as clear of the previous message. The overrun error flag, RXnOVR (CiINTF<15> or CiINTF<14>) and the ERRIF bit (CiINTF<5>) will be set and the message in the MAB will be discarded. If the DBEN bit is clear, RXB1 and RXB0 operate independently. When this is the case, a message intended for RXB0 will not be diverted into RXB1 if RXB0 contains an unread message and the RX0OVR bit will be set. If the DBEN bit is set, the overrun for RXB0 is handled differently. If a valid message is received for RXB0 and RXFUL = 1 indicates that RXB0 is full, and RXFUL = 0 indicates that RXB1 is empty, the message for RXB0 will be loaded into RXB1. An overrun error will not be generated for RXB0. If a valid message is received for RXB0 and RXFUL = 1, and RXFUL = 1 indicating that both RXB0 and RXB1 are full, the message will be lost and an overrun will be indicated for RXB1.
19.4.2
MESSAGE ACCEPTANCE FILTERS
The message acceptance filters and masks are used to determine if a message in the message assembly buffer should be loaded into either of the receive buffers. Once a valid message has been received into the Message Assembly Buffer (MAB), the identifier fields of the message are compared to the filter values. If there is a match, that message will be loaded into the appropriate receive buffer. The acceptance filter looks at incoming messages for the RXIDE bit (CiRXnSID<0>) to determine how to compare the identifiers. If the RXIDE bit is clear, the message is a standard frame, and only filters with the EXIDE bit (CiRXFnSID<0>) clear are compared. If the RXIDE bit is set, the message is an extended frame, and only filters with the EXIDE bit set are compared. Configuring the RXM<1:0> bits to 01 or 10 can override the EXIDE bit.
19.4.5
RECEIVE ERRORS
The CAN module will detect the following receive errors: * Cyclic Redundancy Check (CRC) Error * Bit Stuffing Error * Invalid message receive error These receive errors do not generate an interrupt. However, the receive error counter is incremented by one in case one of these errors occur. The RXWAR bit (CiINTF<9>) indicates that the Receive Error Counter has reached the CPU warning limit of 96 and an interrupt is generated.
19.4.6
RECEIVE INTERRUPTS
19.4.3
MESSAGE ACCEPTANCE FILTER MASKS
Receive interrupts can be divided into 3 major groups, each including various conditions that generate interrupts: * Receive Interrupt A message has been successfully received and loaded into one of the receive buffers. This interrupt is activated immediately after receiving the End-of-Frame (EOF) field. Reading the RXnIF flag will indicate which receive buffer caused the interrupt. * Wake-up interrupt The CAN module has woken up from Disable mode or the device has woken up from Sleep mode.
The mask bits essentially determine which bits to apply the filter to. If any mask bit is set to a zero, then that bit will automatically be accepted regardless of the filter bit. There are 2 programmable acceptance filter masks associated with the receive buffers, one for each buffer.

* Receive Error Interrupts A receive error interrupt will be indicated by the ERRIF bit. This bit shows that an error condition occurred. The source of the error can be determined by checking the bits in the CAN Interrupt Status Register CiINTF. * Invalid message received * If any type of error occurred during reception of the last message, an error will be indicated by the IVRIF bit. * Receiver overrun * The RXnOVR bit indicates that an overrun condition occurred. * Receiver warning * The RXWAR bit indicates that the Receive Error Counter (RERRCNT<7:0>) has reached the Warning limit of 96. * Receiver error passive * The RXEP bit indicates that the Receive Error Counter has exceeded the Error Passive limit of 127 and the module has gone into Error Passive state. Setting TXREQ bit simply flags a message buffer as enqueued for transmission. When the module detects an available bus, it begins transmitting the message which has been determined to have the highest priority. If the transmission completes successfully on the first attempt, the TXREQ bit is cleared automatically and an interrupt is generated if TXIE was set. If the message transmission fails, one of the error condition flags will be set and the TXREQ bit will remain set indicating that the message is still pending for transmission. If the message encountered an error condition during the transmission attempt, the TXERR bit will be set and the error condition may cause an interrupt. If the message loses arbitration during the transmission attempt, the TXLARB bit is set. No interrupt is generated to signal the loss of arbitration.

19.5.1
Message Transmission
TRANSMIT BUFFERS
The CAN module has three transmit buffers. Each of the three buffers occupies 14 bytes of data. Eight of the bytes are the maximum 8 bytes of the transmitted message. Five bytes hold the standard and extended identifiers and other message arbitration information.
The system can also abort a message by clearing the TXREQ bit associated with each message buffer. Setting the ABAT bit (CiCTRL<12>) will request an abort of all pending messages. If the message has not yet started transmission, or if the message started but is interrupted by loss of arbitration or an error, the abort will be processed. The abort is indicated when the module sets the TXABT bit, and the TXnIF flag is not automatically set.
19.5.5
TRANSMISSION ERRORS
The CAN module will detect the following transmission errors: * Acknowledge Error * Form Error * Bit Error These transmission errors will not necessarily generate an interrupt but are indicated by the transmission error counter. However, each of these errors will cause the transmission error counter to be incremented by one. Once the value of the error counter exceeds the value of 96, the ERRIF (CiINTF<5>) and the TXWAR bit (CiINTF<10>) are set. Once the value of the error counter exceeds the value of 96, an interrupt is generated and the TXWAR bit in the error flag register is set.
19.5.2
TRANSMIT MESSAGE PRIORITY
Transmit priority is a prioritization within each node of the pending transmittable messages. There are 4 levels of transmit priority. If TXPRI<1:0> (CiTXnCON<1:0>, where n = 0, 1 or 2 represents a particular transmit buffer) for a particular message buffer is set to `11', that buffer has the highest priority. If TXPRI<1:0> for a particular message buffer is set to `10' or `01', that buffer has an intermediate priority. If TXPRI<1:0> for a particular message buffer is `00', that buffer has the lowest priority.
19.5.3
TRANSMISSION SEQUENCE
To initiate transmission of the message, the TXREQ bit (CiTXnCON<3>) must be set. The CAN bus module resolves any timing conflicts between setting of the TXREQ bit and the Start of Frame (SOF), ensuring that if the priority was changed, it is resolved correctly before the SOF occurs. When TXREQ is set, the TXABT (CiTXnCON<6>), TXLARB (CiTXnCON<5>) and TXERR (CiTXnCON<4>) flag bits are automatically cleared.

19.5.6 TRANSMIT INTERRUPTS
19.6
Baud Rate Setting
Transmit interrupts can be divided into 2 major groups, each including various conditions that generate interrupts: * Transmit Interrupt At least one of the three transmit buffers is empty (not scheduled) and can be loaded to schedule a message for transmission. Reading the TXnIF flags will indicate which transmit buffer is available and caused the interrupt. * Transmit Error Interrupts A transmission error interrupt will be indicated by the ERRIF flag. This flag shows that an error condition occurred. The source of the error can be determined by checking the error flags in the CAN Interrupt Status register, CiINTF. The flags in this register are related to receive and transmit errors. * Transmitter Warning Interrupt * The TXWAR bit indicates that the Transmit Error Counter has reached the CPU warning limit of 96. * Transmitter Error Passive * The TXEP bit (CiINTF<12>) indicates that the Transmit Error Counter has exceeded the Error Passive limit of 127 and the module has gone to Error Passive state. * Bus Off * The TXBO bit (CiINTF<13>) indicates that the Transmit Error Counter has exceeded 255 and the module has gone to Bus Off state.
All nodes on any particular CAN bus must have the same nominal bit rate. In order to set the baud rate, the following parameters have to be initialized: * * * * * * Synchronization Jump Width Baud rate prescaler Phase segments Length determination of Phase2 Seg Sample Point Propagation segment bits
19.6.1
BIT TIMING
All controllers on the CAN bus must have the same baud rate and bit length. However, different controllers are not required to have the same master oscillator clock. At different clock frequencies of the individual controllers, the baud rate has to be adjusted by adjusting the number of time quanta in each segment. The Nominal Bit Time can be thought of as being divided into separate non-overlapping time segments. These segments are shown in Figure 19-2. * * * * Synchronization segment (Sync Seg) Propagation time segment (Prop Seg) Phase segment 1 (Phase1 Seg) Phase segment 2 (Phase2 Seg)
The time segments and also the nominal bit time are made up of integer units of time called time quanta or TQ. By definition, the Nominal Bit Time has a minimum of 8 TQ and a maximum of 25 TQ. Also, by definition, the minimum nominal bit time is 1 sec, corresponding to a maximum bit rate of 1 MHz.

19.6.2 PRESCALER SETTING 19.6.5 SAMPLE POINT
There is a programmable prescaler, with integral values ranging from 1 to 64, in addition to a fixed divideby-2 for clock generation. The Time Quantum (TQ) is a fixed unit of time derived from the oscillator period, and is given by Equation 19-1, where FCAN is FCY (if the CANCKS bit is set or 4 FCY (if CANCKS is cleared). Note: FCAN must not exceed 30 MHz. If CANCKS = 0, then FCY must not exceed 7.5 MHz. The Sample Point is the point of time at which the bus level is read and interpreted as the value of that respective bit. The location is at the end of Phase1 Seg. If the bit timing is slow and contains many TQ, it is possible to specify multiple sampling of the bus line at the sample point. The level determined by the CAN bus then corresponds to the result from the majority decision of three values. The majority samples are taken at the sample point and twice before with a distance of TQ/2. The CAN module allows the user to chose between sampling three times at the same point or once at the same point, by setting or clearing the SAM bit (CiCFG2<6>). Typically, the sampling of the bit should take place at about 60-70% through the bit time, depending on the system parameters.
EQUATION 19-1:
TIME QUANTUM FOR CLOCK GENERATION
TQ = 2 ( BRP<5:0> + 1 ) / FCAN
19.6.3
PROPAGATION SEGMENT
19.6.6
SYNCHRONIZATION
This part of the bit time is used to compensate physical delay times within the network. These delay times consist of the signal propagation time on the bus line and the internal delay time of the nodes. The Propagation Segment can be programmed from 1 TQ to 8 TQ by setting the PRSEG<2:0> bits (CiCFG2<2:0>).
19.6.4
PHASE SEGMENTS
To compensate for phase shifts between the oscillator frequencies of the different bus stations, each CAN controller must be able to synchronize to the relevant signal edge of the incoming signal. When an edge in the transmitted data is detected, the logic will compare the location of the edge to the expected time (Synchronous Segment). The circuit will then adjust the values of Phase1 Seg and Phase2 Seg. There are 2 mechanisms used to synchronize.
The phase segments are used to optimally locate the sampling of the received bit within the transmitted bit time. The sampling point is between Phase1 Seg and Phase2 Seg. These segments are lengthened or shortened by re-synchronization. The end of the Phase1 Seg determines the sampling point within a bit period. The segment is programmable from 1 TQ to 8 TQ. Phase2 Seg provides delay to the next transmitted data transition. The segment is programmable from 1 TQ to 8 TQ, or it may be defined to be equal to the greater of Phase1 Seg or the Information Processing Time (2 TQ). The Phase1 Seg is initialized by setting bits SEG1PH<2:0> (CiCFG2<5:3>), and Phase2 Seg is initialized by setting SEG2PH<2:0> (CiCFG2<10:8>). The following requirement must be fulfilled while setting the lengths of the Phase Segments: * Propagation Segment + Phase1 Seg > = Phase2 Seg
19.6.6.1
Hard Synchronization
Hard Synchronization is only done whenever there is a 'recessive' to 'dominant' edge during Bus Idle, indicating the start of a message. After hard synchronization, the bit time counters are restarted with the Synchronous Segment. Hard synchronization forces the edge which has caused the hard synchronization to lie within the synchronization segment of the restarted bit time. If a hard synchronization is done, there will not be a re-synchronization within that bit time.
19.6.6.2
Re-synchronization
As a result of re-synchronization, Phase1 Seg may be lengthened or Phase2 Seg may be shortened. The amount of lengthening or shortening of the phase buffer segment has an upper bound known as the Synchronization Jump Width, and is specified by the SJW<1:0> bits (CiCFG1<7:6>). The value of the synchronization jump width will be added to Phase1 Seg or subtracted from Phase2 Seg. The re-synchronization jump width is programmable between 1 TQ and 4 TQ. The following requirement must be fulfilled while setting the SJW<1:0> bits: * Phase2 Seg > Synchronization Jump Width

20.0 10-BIT HIGH SPEED ANALOGTO-DIGITAL CONVERTER (A/D) MODULE
The A/D module has six 16-bit registers: * * * * * * A/D Control Register1 (ADCON1) A/D Control Register2 (ADCON2) A/D Control Register3 (ADCON3) A/D Input Select Register (ADCHS) A/D Port Configuration Register (ADPCFG) A/D Input Scan Selection Register (ADCSSL)
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046).
The10-bit high-speed analog-to-digital converter (A/D) allows conversion of an analog input signal to a 10-bit digital number. This module is based on a Successive Approximation Register (SAR) architecture, and provides a maximum sampling rate of 500 ksps. The A/D module has 16 analog inputs which are multiplexed into four sample and hold amplifiers. The output of the sample and hold is the input into the converter, which generates the result. The analog reference voltages are software selectable to either the device supply voltage (AVDD/AVSS) or the voltage level on the (VREF+/VREF-) pin. The A/D converter has a unique feature of being able to operate while the device is in Sleep mode.
The ADCON1, ADCON2 and ADCON3 registers control the operation of the A/D module. The ADCHS register selects the input channels to be converted. The ADPCFG register configures the port pins as analog inputs or as digital I/O. The ADCSSL register selects inputs for scanning. Note: The SSRC<2:0>, ASAM, SIMSAM, SMPI<3:0>, BUFM and ALTS bits, as well as the ADCON3 and ADCSSL registers, must not be written to while ADON = 1. This would lead to indeterminate results.
The block diagram of the A/D module is shown in Figure 20-1.

20.1 A/D Result Buffer
The module contains a 16-word dual port read-only buffer, called ADCBUF0...ADCBUFF, to buffer the A/D results. The RAM is 10-bits wide, but is read into different format 16-bit words. The contents of the sixteen A/D conversion result buffer registers, ADCBUF0 through ADCBUFF, cannot be written by user software. The CHPS bits selects how many channels are sampled. This can vary from 1, 2 or 4 channels. If CHPS selects 1 channel, the CH0 channel will be sampled at the sample clock and converted. The result is stored in the buffer. If CHPS selects 2 channels, the CH0 and CH1 channels will be sampled and converted. If CHPS selects 4 channels, the CH0, CH1, CH2 and CH3 channels will be sampled and converted. The SMPI bits select the number of acquisition/conversion sequences that would be performed before an interrupt occurs. This can vary from 1 sample per interrupt to 16 samples per interrupt. The user cannot program a combination of CHPS and SMPI bits that specifies more than 16 conversions per interrupt, or 8 conversions per interrupt, depending on the BUFM bit. The BUFM bit, when set, will split the 16--word results buffer (ADCBUF0...ADCBUFF) into two 8-word groups. Writing to the 8-word buffers will be alternated on each interrupt event. Use of the BUFM bit will depend on how much time is available for moving data out of the buffers after the interrupt, as determined by the application. If the processor can quickly unload a full buffer within the time it takes to acquire and convert one channel, the BUFM bit can be `0' and up to 16 conversions may be done per interrupt. The processor will have one sample and conversion time to move the sixteen conversions. If the processor cannot unload the buffer within the acquisition and conversion time, the BUFM bit should be `1'. For example, if SMPI<3:0> (ADCON2<5:2>) = 0111, then eight conversions will be loaded into 1/2 of the buffer, following which an interrupt occurs. The next eight conversions will be loaded into the other 1/2 of the buffer. The processor will have the entire time between interrupts to move the eight conversions. The ALTS bit can be used to alternate the inputs selected during the sampling sequence. The input multiplexer has two sets of sample inputs: MUX A and MUX B. If the ALTS bit is `0', only the MUX A inputs are selected for sampling. If the ALTS bit is `1' and SMPI<3:0> = 0000, on the first sample/convert sequence, the MUX A inputs are selected, and on the next acquire/convert sequence, the MUX B inputs are selected. The CSCNA bit (ADCON2<10>) will allow the CH0 channel inputs to be alternately scanned across a selected number of analog inputs for the MUX A group. The inputs are selected by the ADCSSL register. If a particular bit in the ADCSSL register is `1', the corresponding input is selected. The inputs are always scanned from lower to higher numbered inputs, starting after each interrupt. If the number of inputs selected is greater than the number of samples taken per interrupt, the higher numbered inputs are unused.
20.2
Conversion Operation
After the A/D module has been configured, the sample acquisition is started by setting the SAMP bit. Various sources, such as a programmable bit, timer time-outs and external events, will terminate acquisition and start a conversion. When the A/D conversion is complete, the result is loaded into ADCBUF0...ADCBUFF, and the A/D interrupt flag ADIF and the DONE bit are set after the number of samples specified by the SMPI bit. The following steps should be followed for doing an A/D conversion: 1. 2. 3. 4. 5. 6. 7. Configure the A/D module: Configure analog pins, voltage reference and digital I/O Select A/D input channels Select A/D conversion clock Select A/D conversion trigger Turn on A/D module Configure A/D interrupt (if required): Clear ADIF bit Select A/D interrupt priority Start sampling. Wait the required acquisition time. Trigger acquisition end, start conversion Wait for A/D conversion to complete, by either: Waiting for the A/D interrupt Read A/D result buffer, clear ADIF if required.
20.3
Selecting the Conversion Sequence
Several groups of control bits select the sequence in which the A/D connects inputs to the sample/hold channels, converts channels, writes the buffer memory, and generates interrupts. The sequence is controlled by the sampling clocks. The SIMSAM bit controls the acquire/convert sequence for multiple channels. If the SIMSAM bit is `0', the two or four selected channels are acquired and converted sequentially, with two or four sample clocks. If the SIMSAM bit is `1', two or four selected channels are acquired simultaneously, with one sample clock. The channels are then converted sequentially. Obviously, if there is only 1 channel selected, the SIMSAM bit is not applicable.

20.4 Programming the Start of Conversion Trigger 20.6 Selecting the A/D Conversion Clock
The conversion trigger will terminate acquisition and start the requested conversions. The SSRC<2:0> bits select the source of the conversion trigger. The SSRC bits provide for up to 5 alternate sources of conversion trigger. When SSRC<2:0> = 000, the conversion trigger is under software control. Clearing the SAMP bit will cause the conversion trigger. When SSRC<2:0> = 111 (Auto Start mode), the conversion trigger is under A/D clock control. The SAMC bits select the number of A/D clocks between the start of acquisition and the start of conversion. This provides the fastest conversion rates on multiple channels. SAMC must always be at least 1 clock cycle. Other trigger sources can come from timer modules, Motor Control PWM module, or external interrupts. Note: To operate the A/D at the maximum specified conversion speed, the Auto Convert Trigger option should be selected (SSRC = 111) and the Auto Sample Time bits shoud be set to 1 TAD (SAMC = 00001). This configuration will give a total conversion period (sample + convert) of 13 TAD. The use of any other conversion trigger will result in additional TAD cycles to synchronize the external event to the A/D. The A/D conversion requires 12 TAD. The source of the A/D conversion clock is software selected using a six bit counter. There are 64 possible options for TAD.
EQUATION 20-1:
A/D CONVERSION CLOCK
TAD = TCY * (0.5*(ADCS<5:0> +1)) TAD ADCS<5:0> = 2 -1 TCY The internal RC oscillator is selected by setting the ADRC bit. For correct A/D conversions, the A/D conversion clock (TAD) must be selected to ensure a minimum TAD time of 154 nsec (for VDD = 5V). Refer to the Electrical Specifications section for minimum TAD under other operating conditions. Example 20-1 shows a sample calculation for the ADCS<5:0> bits, assuming a device operating speed of 30 MIPS.
EXAMPLE 20-1:
A/D CONVERSION CLOCK CALCULATION
Minimum TAD = 154 nsec TCY = 33 nsec (30 MIPS) ADCS<5:0> = 2 TAD -1 TCY 154 nsec =2* -1 33 nsec = 8.33
20.5
Aborting a Conversion
Clearing the ADON bit during a conversion will abort the current conversion and stop the sampling sequencing. The ADCBUF will not be updated with the partially completed A/D conversion sample. That is, the ADCBUF will continue to contain the value of the last completed conversion (or the last value written to the ADCBUF register). If the clearing of the ADON bit coincides with an auto start, the clearing has a higher priority. After the A/D conversion is aborted, a 2 TAD wait is required before the next sampling may be started by setting the SAMP bit. If sequential sampling is specified, the A/D will continue at the next sample pulse which corresponds with the next channel converted. If simultaneous sampling is specified, the A/D will continue with the next multi-channel group conversion sequence.
Therefore, Set ADCS<5:0> = 9 Actual TAD = TCY (ADCS<5:0> + 1) 2 33 nsec = (9 + 1) 2 = 165 nsec

20.7 A/D Acquisition Requirements
The analog input model of the 10-bit A/D converter is shown in Figure 20-2. The total sampling time for the A/D is a function of the internal amplifier settling time, device VDD and the holding capacitor charge time. For the A/D converter to meet its specified accuracy, the charge holding capacitor (CHOLD) must be allowed to fully charge to the voltage level on the analog input pin. The source impedance (RS), the interconnect impedance (RIC), and the internal sampling switch (RSS) impedance combine to directly affect the time required to charge the capacitor CHOLD. The combined impedance of the analog sources must therefore be small enough to fully charge the holding capacitor within the chosen sample time. To minimize the effects of pin leakage currents on the accuracy of the A/D converter, the maximum recommended source impedance, RS, is 5 k. After the analog input channel is selected (changed), this sampling function must be completed prior to starting the conversion. The internal holding capacitor will be in a discharged state prior to each sample operation. The user must allow at least 1 TAD period of sampling time, TSAMP, between conversions to allow each sample to be acquired. This sample time may be controlled manually in software by setting/clearing the SAMP bit, or it may be automatically controlled by the A/D converter. In an automatic configuration, the user must allow enough time between conversion triggers so that the minimum sample time can be satisfied. Refer to the Electrical Specifications for TAD and sample time requirements.

20.8 Module Power-down Modes
The module has 3 internal power modes. When the ADON bit is `1', the module is in Active mode; it is fully powered and functional. When ADON is `0', the module is in Off mode. The digital and analog portions of the circuit are disabled for maximum current savings. In order to return to the Active mode from Off mode, the user must wait for the ADC circuitry to stabilize. If the A/D interrupt is enabled, the device will wake-up from Sleep. If the A/D interrupt is not enabled, the A/D module will then be turned off, although the ADON bit will remain set.

A device Reset forces all registers to their Reset state. This forces the A/D module to be turned off, and any conversion and acquisition sequence is aborted. The values that are in the ADCBUF registers are not modified. The A/D result register will contain unknown data after a Power-on Reset.
When the device enters Sleep mode, all clock sources to the module are shutdown and stay at logic `0'. If Sleep occurs in the middle of a conversion, the conversion is aborted. The converter will not continue with a partially completed conversion on exit from Sleep mode. Register contents are not affected by the device entering or leaving Sleep mode. The A/D module can operate during Sleep mode if the A/D clock source is set to RC (ADRC = 1). When the RC clock source is selected, the A/D module waits one instruction cycle before starting the conversion. This allows the SLEEP instruction to be executed, which eliminates all digital switching noise from the conversion. When the conversion is complete, the Done bit will be set and the result loaded into the ADCBUF register.
20.11 Output Formats
The A/D result is 10-bits wide. The data buffer RAM is also 10-bits wide. The 10-bit data can be read in one of four different formats. The FORM<1:0> bits select the format. Each of the output formats translates to a 16-bit result on the data bus. Write data will always be in right justified (integer) format.

20.12 Configuring Analog Port Pins
The use of the ADPCFG and TRIS registers control the operation of the A/D port pins. The port pins that are desired as analog inputs must have their corresponding TRIS bit set (input). If the TRIS bit is cleared (output), the digital output level (VOH or VOL) will be converted. The A/D operation is independent of the state of the CH0SA<3:0>/CH0SB<3:0> bits and the TRIS bits. When reading the PORT register, all pins configured as analog input channels will read as cleared. Pins configured as digital inputs will not convert an analog input. Analog levels on any pin that is defined as a digital input (including the ANx pins), may cause the input buffer to consume current that exceeds the device specifications.
20.13 Connection Considerations
The analog inputs have diodes to VDD and VSS as ESD protection. This requires that the analog input be between VDD and VSS. If the input voltage exceeds this range by greater than 0.3V (either direction), one of the diodes becomes forward biased and it may damage the device if the input current specification is exceeded. An external RC filter is sometimes added for antialiasing of the input signal. The R component should be selected to ensure that the sampling time requirements are satisfied. Any external components connected (via high impedance) to an analog input pin (capacitor, zener diode, etc.) should have very little leakage current at the pin.

21.0 SYSTEM INTEGRATION
21.1 Oscillator System Overview
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046). For more information on the device instruction set and programming, refer to the dsPIC30F Programmer's Reference Manual (DS70030).
The dsPIC30F oscillator system has the following modules and features: * Various external and internal oscillator options as clock sources * An on-chip PLL to boost internal operating frequency * A clock switching mechanism between various clock sources * Programmable clock postscaler for system power savings * A Fail-Safe Clock Monitor (FSCM) that detects clock failure and takes fail-safe measures * Clock Control Register OSCCON * Configuration bits for main oscillator selection Table 21-1 provides a summary of the dsPIC30F oscillator operating modes. A simplified diagram of the oscillator system is shown in Figure 21-1. Configuration bits determine the clock source upon Power-on Reset (POR) and Brown-out Reset (BOR). Thereafter, the clock source can be changed between permissible clock sources. The OSCCON register controls the clock switching and reflects system clock related status bits.
There are several features intended to maximize system reliability, minimize cost through elimination of external components, provide power saving operating modes and offer code protection: * Oscillator Selection * Reset - Power-on Reset (POR) - Power-up Timer (PWRT) - Oscillator Start-up Timer (OST) - Programmable Brown-out Reset (BOR) * Watchdog Timer (WDT) * Power Saving modes (Sleep and Idle) * Code Protection * Unit ID Locations * In-Circuit Serial Programming (ICSP) dsPIC30F devices have a Watchdog Timer, which is permanently enabled via the configuration bits or can be software controlled. It runs off its own RC oscillator for added reliability. There are two timers that offer necessary delays on power-up. One is the Oscillator Startup Timer (OST), intended to keep the chip in Reset until the crystal oscillator is stable. The other is the Powerup Timer (PWRT), which provides a delay on power-up only, designed to keep the part in Reset while the power supply stabilizes. With these two timers on-chip, most applications need no external Reset circuitry. Sleep mode is designed to offer a very low current Power-down mode. The user can wake-up from Sleep through external Reset, Watchdog Timer Wake-up or through an interrupt. Several oscillator options are also made available to allow the part to fit a wide variety of applications. In the Idle mode, the clock sources are still active, but the CPU is shut-off. The RC oscillator option saves system cost, while the LP crystal option saves power.

Oscillator Configurations
INITIAL CLOCK SOURCE SELECTION
While coming out of Power-on Reset or Brown-out Reset, the device selects its clock source based on: a) b) FOS<1:0> configuration bits that select one of four oscillator groups. AND FPR<3:0> configuration bits that select one of 13 oscillator choices within the primary group.
The selection is as shown in Table 21-2.

Note 1: OSC2 pin function is determined by the Primary Oscillator mode selection (FPR<3:0>). 2: Note that OSC1 pin cannot be used as an I/O pin, even if the secondary oscillator or an internal clock source is selected at all times.
21.2.2
OSCILLATOR START-UP TIMER (OST)
21.2.3
LP OSCILLATOR CONTROL
In order to ensure that a crystal oscillator (or ceramic resonator) has started and stabilized, an oscillator start-up timer is included. It is a simple 10-bit counter that counts 1024 TOSC cycles before releasing the oscillator clock to the rest of the system. The time-out period is designated as TOST. The TOST time is involved every time the oscillator has to restart (i.e., on POR, BOR and wake-up from Sleep). The oscillator start-up timer is applied to the LP Oscillator, XT, XTL, and HS modes (upon wake-up from Sleep, POR and BOR) for the primary oscillator.
Enabling the LP oscillator is controlled with two elements: 1. 2. The current oscillator group bits COSC<1:0>. The LPOSCEN bit (OSCON register).
The LP oscillator is ON (even during Sleep mode) if LPOSCEN = 1. The LP oscillator is the device clock if: * COSC<1:0> = 00 (LP selected as main oscillator) and * LPOSCEN = 1 Keeping the LP oscillator ON at all times allows for a fast switch to the 32 kHz system clock for lower power operation. Returning to the faster main oscillator will still require a start-up time.

21.2.4 PHASE LOCKED LOOP (PLL) 21.2.6
The PLL multiplies the clock which is generated by the primary oscillator. The PLL is selectable to have either gains of x4, x8, and x16. Input and output frequency ranges are summarized in Table 21-3.
LOW POWER RC OSCILLATOR (LPRC)

PLL FREQUENCY RANGE
PLL Multiplier x4 x8 x16 Fout 16 MHz-40 MHz 32 MHz-80 MHz 64 MHz-120 MHz
The LPRC oscillator is a component of the Watchdog Timer (WDT) and oscillates at a nominal frequency of 512 kHz. The LPRC oscillator is the clock source for the Power-up Timer (PWRT) circuit, WDT and clock monitor circuits. It may also be used to provide a low frequency clock source option for applications where power consumption is critical, and timing accuracy is not required. The LPRC oscillator is always enabled at a Power-on Reset, because it is the clock source for the PWRT. After the PWRT expires, the LPRC oscillator will remain ON if one of the following is TRUE: * The Fail-Safe Clock Monitor is enabled * The WDT is enabled * The LPRC oscillator is selected as the system clock via the COSC<1:0> control bits in the OSCCON register If one of the above conditions is not true, the LPRC will shut-off after the PWRT expires. Note 1: OSC2 pin function is determined by the Primary Oscillator mode selection (FPR<3:0>). 2: Note that OSC1 pin cannot be used as an I/O pin, even if the secondary oscillator or an internal clock source is selected at all times.
The PLL features a lock output, which is asserted when the PLL enters a phase locked state. Should the loop fall out of lock (e.g., due to noise), the lock signal will be rescinded. The state of this signal is reflected in the read only LOCK bit in the OSCCON register.
21.2.5
FAST RC OSCILLATOR (FRC)
The FRC oscillator is a fast (8 MHz nominal) internal RC oscillator. This oscillator is intended to provide reasonable device operating speeds without the use of an external crystal, ceramic resonator, or RC network. The dsPIC30F operates from the FRC oscillator whenever the Current Oscillator Selection control bits in the OSCCON register (OSCCON<13:12>) are set to `01'. There are four tuning bits (TUN<3:0>) for the FRC oscillator in the OSCCON register. These tuning bits allow the FRC oscillator frequency to be adjusted as close to 8 MHz as possible, depending on the device operating conditions. The FRC oscillator frequency has been calibrated during factory testing. Table 21-4 describes the adjustment range of the TUN<3:0> bits.

The Fail-Safe Clock Monitor (FSCM) allows the device to continue to operate even in the event of an oscillator failure. The FSCM function is enabled by appropriately programming the FCKSM configuration bits (Clock Switch and Monitor Selection bits) in the FOSC device configuration register. If the FSCM function is enabled, the LPRC Internal oscillator will run at all times (except during Sleep mode) and will not be subject to control by the SWDTEN bit. In the event of an oscillator failure, the FSCM will generate a Clock Failure Trap event and will switch the system clock over to the FRC oscillator. The user will then have the option to either attempt to restart the oscillator or execute a controlled shutdown. The user may decide to treat the Trap as a warm Reset by simply loading the Reset address into the oscillator fail trap vector. In this event, the CF (Clock Fail) status bit (OSCCON<3>) is also set whenever a clock failure is recognized. In the event of a clock failure, the WDT is unaffected and continues to run on the LPRC clock.

dsPIC30F6010
If the oscillator has a very slow start-up time coming out of POR, BOR or Sleep, it is possible that the PWRT timer will expire before the oscillator has started. In such cases, the FSCM will be activated and the FSCM will initiate a Clock Failure Trap, and the COSC<1:0> bits are loaded with FRC oscillator selection. This will effectively shut-off the original oscillator that was trying to start. The user may detect this situation and restart the oscillator in the Clock Fail Trap ISR. Upon a clock failure detection, the FSCM module will initiate a clock switch to the FRC Oscillator as follows: 1. 2. 3. The COSC bits (OSCCON<13:12>) are loaded with the FRC Oscillator selection value. CF bit is set (OSCCON<3>). OSWEN control bit (OSCCON<0>) is cleared. If configuration bits FCKSM<1:0> = 1x, then the clock switching and fail-safe clock monitor functions are disabled. This is the default configuration bit setting. If clock switching is disabled, then the FOS<1:0> and FPR<3:0> bits directly control the oscillator selection and the COSC<1:0> bits do not control the clock selection. However, these bits will reflect the clock source selection. Note: The application should not attempt to switch to a clock of frequency lower than 100 KHz when the fail-safe clock monitor is enabled. If such clock switching is performed, the device may generate an oscillator fail trap and switch to the Fast RC oscillator.
For the purpose of clock switching, the clock sources are sectioned into four groups: 1. 2. 3. 4. Primary Secondary Internal FRC Internal LPRC
21.2.8
PROTECTION AGAINST ACCIDENTAL WRITES TO OSCCON
A write to the OSCCON register is intentionally made difficult because it controls clock switching and clock scaling. To write to the OSCCON low byte, the following code sequence must be executed without any other instructions in between: * Byte Write "0x46" to OSCCON low * Byte Write "0x57" to OSCCON low Byte Write is allowed for one instruction cycle. Write the desired value or use bit manipulation instruction. To write to the OSCCON high byte, the following instructions must be executed without any other instructions in between: * Byte Write "0x78" to OSCCON high * Byte Write "0x9A" to OSCCON high Byte Write is allowed for one instruction cycle. Write the desired value or use bit manipulation instruction.
The user can switch between these functional groups, but cannot switch between options within a group. If the primary group is selected, then the choice within the group is always determined by the FPR<3:0> configuration bits. The OSCCON register holds the CONTROL and STATUS bits related to clock switching. * COSC<1:0>: Read only status bits always reflect the current oscillator group in effect. * NOSC<1:0>: Control bits which are written to indicate the new oscillator group of choice. - On POR and BOR, COSC<1:0> and NOSC<1:0> are both loaded with the Configuration bit values FOS<1:0>. * LOCK: The LOCK status bit indicates a PLL lock. * CF: Read only status bit indicating if a clock fail detect has occurred. * OSWEN: Control bit changes from a `0' to a `1' when a clock transition sequence is initiated. Clearing the OSWEN control bit will abort a clock transition in progress (used for hang-up situations).

21.3 Reset
The PIC18F1220/1320 differentiates between various kinds of Reset: a) b) c) d) e) f) g) h) Power-on Reset (POR) MCLR Reset during normal operation MCLR Reset during Sleep Watchdog Timer (WDT) Reset (during normal operation) Programmable Brown-out Reset (BOR) RESET Instruction Reset cause by trap lockup (TRAPR) Reset caused by illegal opcode, or by using an uninitialized W register as an address pointer (IOPUWR) Different registers are affected in different ways by various Reset conditions. Most registers are not affected by a WDT wake-up, since this is viewed as the resumption of normal operation. Status bits from the RCON register are set or cleared differently in different Reset situations, as indicated in Table 21-5. These bits are used in software to determine the nature of the Reset. A block diagram of the on-chip Reset circuit is shown in Figure 21-2. A MCLR noise filter is provided in the MCLR Reset path. The filter detects and ignores small pulses. Internally generated Resets do not drive MCLR pin low.

21.3.1
POR: POWER-ON RESET
A power-on event will generate an internal POR pulse when a VDD rise is detected. The Reset pulse will occur at the POR circuit threshold voltage (VPOR), which is nominally 1.85V. The device supply voltage characteristics must meet specified starting voltage and rise rate requirements. The POR pulse will reset a POR timer and place the device in the Reset state. The POR also selects the device clock source identified by the oscillator configuration fuses.
The POR circuit inserts a small delay, TPOR, which is nominally 10 s and ensures that the device bias circuits are stable. Furthermore, a user selected powerup time-out (TPWRT) is applied. The TPWRT parameter is based on device configuration bits and can be 0 ms (no delay), 4 ms, 16 ms or 64 ms. The total delay is at device power-up TPOR + TPWRT. When these delays have expired, SYSRST will be negated on the next leading edge of the Q1 clock, and the PC will jump to the Reset vector. The timing for the SYSRST signal is shown in Figure 21-3 through Figure 21-5.

21.3.1.1 POR with Long Crystal Start-up Time (with FSCM Enabled)
The oscillator start-up circuitry is not linked to the POR circuitry. Some crystal circuits (especially low frequency crystals) will have a relatively long start-up time. Therefore, one or more of the following conditions is possible after the POR timer and the PWRT have expired: * The oscillator circuit has not begun to oscillate. * The oscillator start-up timer has NOT expired (if a crystal oscillator is used). * The PLL has not achieved a LOCK (if PLL is used). If the FSCM is enabled and one of the above conditions is true, then a Clock Failure Trap will occur. The device will automatically switch to the FRC oscillator and the user can switch to the desired crystal oscillator in the trap ISR. A BOR will generate a Reset pulse which will reset the device. The BOR will select the clock source, based on the device configuration bit values (FOS<1:0> and FPR<3:0>). Furthermore, if an Oscillator mode is selected, the BOR will activate the Oscillator Start-up Timer (OST). The system clock is held until OST expires. If the PLL is used, then the clock will be held until the LOCK bit (OSCCON<5>) is "1". Concurrently, the POR time-out (TPOR) and the PWRT time-out (TPWRT) will be applied before the internal Reset is released. If TPWRT = 0 and a crystal oscillator is being used, then a nominal delay of TFSCM = 100 s is applied. The total delay in this case is (TPOR + TFSCM). The BOR status bit (RCON<1>) will be set to indicate that a BOR has occurred. The BOR circuit, if enabled, will continue to operate while in Sleep or Idle modes and will reset the device should VDD fall below the BOR threshold voltage.
21.3.1.2
Operating without FSCM and PWRT
FIGURE 21-6:
If the FSCM is disabled and the Power-up Timer (PWRT) is also disabled, then the device will exit rapidly from Reset on power-up. If the clock source is FRC, LPRC, EXTRC or EC, it will be active immediately. If the FSCM is disabled and the system clock has not started, the device will be in a frozen state at the Reset vector until the system clock starts. From the user's perspective, the device will appear to be in Reset until a system clock is available.

The BOR (Brown-out Reset) module is based on an internal voltage reference circuit. The main purpose of the BOR module is to generate a device Reset when a brown-out condition occurs. Brown-out conditions are generally caused by glitches on the AC mains (i.e., missing portions of the AC cycle waveform due to bad power transmission lines or voltage sags due to excessive current draw when a large inductive load is turned on). The BOR module allows selection of one of the following voltage trip points: * * * * 2.0V 2.7V 4.2V 4.5V Note: The BOR voltage trip points indicated here are nominal values provided for design guidance only.
Note 1: External Power-on Reset circuit is required only if the VDD power-up slope is too slow. The diode D helps discharge the capacitor quickly when VDD powers down. 2: R should be suitably chosen so as to make sure that the voltage drop across R does not violate the device's electrical specification. 3: R1 should be suitably chosen so as to limit any current flowing into MCLR from external capacitor C, in the event of MCLR/VPP pin breakdown due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS).
Note:
Dedicated supervisory devices, such as the MCP1XX and MCP8XX, may also be used as an external Power-on Reset circuit.

21.4.1
Watchdog Timer (WDT)
WATCHDOG TIMER OPERATION
21.6
Power Saving Modes
The primary function of the Watchdog Timer (WDT) is to reset the processor in the event of a software malfunction. The WDT is a free running timer, which runs off an on-chip RC oscillator, requiring no external component. Therefore, the WDT timer will continue to operate even if the main processor clock (e.g., the crystal oscillator) fails.
There are two power saving states that can be entered through the execution of a special instruction, PWRSAV. These are: Sleep and Idle. The format of the PWRSAV instruction is as follows: PWRSAV , where `parameter' defines Idle or Sleep mode.
21.6.1
SLEEP MODE
21.4.2
ENABLING AND DISABLING THE WDT
The Watchdog Timer can be "Enabled" or "Disabled" only through a configuration bit (FWDTEN) in the configuration register FWDT. Setting FWDTEN = 1 enables the Watchdog Timer. The enabling is done when programming the device. By default, after chip-erase, FWDTEN bit = 1. Any device programmer capable of programming dsPIC30F devices allows programming of this and other configuration bits. If enabled, the WDT will increment until it overflows or "times out". A WDT time-out will force a device Reset (except during Sleep). To prevent a WDT time-out, the user must clear the Watchdog Timer using a CLRWDT instruction. If a WDT times out during Sleep, the device will wakeup. The WDTO bit in the RCON register will be cleared to indicate a wake-up resulting from a WDT time-out. Setting FWDTEN = 0 allows user software to enable/ disable the Watchdog Timer via the SWDTEN (RCON<5>) control bit.
In Sleep mode, the clock to the CPU and peripherals is shutdown. If an on-chip oscillator is being used, it is shutdown. The fail-safe clock monitor is not functional during Sleep, since there is no clock to monitor. However, LPRC clock remains active if WDT is operational during Sleep. The Brown-out protection circuit and the Low Voltage Detect circuit, if enabled, will remain functional during Sleep. The processor wakes up from Sleep if at least one of the following conditions has occurred: * any interrupt that is individually enabled and meets the required priority level * any Reset (POR, BOR and MCLR) * WDT time-out On waking up from Sleep mode, the processor will restart the same clock that was active prior to entry into Sleep mode. When clock switching is enabled, bits COSC<1:0> will determine the oscillator source that will be used on wake-up. If clock switch is disabled, then there is only one system clock. Note: If a POR or BOR occurred, the selection of the oscillator is based on the FOS<1:0> and FPR<3:0> configuration bits.
21.5
Low Voltage Detect
The Low Voltage Detect (LVD) module is used to detect when the VDD of the device drops below a threshold value VLVD, which is determined by the LVDL<3:0> bits (RCON<11:8>) and is thus user-programmable. The internal voltage reference circuitry requires a nominal amount of time to stabilize, and the BGST bit (RCON<13>) indicates when the voltage reference has stabilized. In some devices, the LVD threshold voltage may be applied externally on the LVDIN pin. The LVD module is enabled by setting the LVDEN bit (RCON<12>).
If the clock source is an oscillator, the clock to the device will be held off until OST times out (indicating a stable oscillator). If PLL is used, the system clock is held off until LOCK = 1 (indicating that the PLL is stable). In either case, TPOR, TLOCK and TPWRT delays are applied. If EC, FRC, LPRC or EXTRC oscillators are used, then a delay of TPOR (~ 10 s) is applied. This is the smallest delay possible on wake-up from Sleep. Moreover, if LP oscillator was active during Sleep, and LP is the oscillator used on wake-up, then the start-up delay will be equal to TPOR. PWRT delay and OST timer delay are not applied. In order to have the smallest possible start-up delay when waking up from Sleep, one of these faster wake-up options should be selected before entering Sleep.

Any interrupt that is individually enabled (using the corresponding IE bit) and meets the prevailing priority level will be able to wake-up the processor. The processor will process the interrupt and branch to the ISR. The Sleep status bit in RCON register is set upon wake-up. Note: In spite of various delays applied (TPOR, TLOCK and TPWRT), the crystal oscillator (and PLL) may not be active at the end of the time-out (e.g., for low frequency crystals. In such cases), if FSCM is enabled, then the device will detect this as a clock failure and process the Clock Failure Trap, the FRC oscillator will be enabled, and the user will have to re-enable the crystal oscillator. If FSCM is not enabled, then the device will simply suspend execution of code until the clock is stable, and will remain in Sleep until the oscillator clock has started. Any interrupt that is individually enabled (using IE bit) and meets the prevailing priority level will be able to wake-up the processor. The processor will process the interrupt and branch to the ISR. The Idle status bit in RCON register is set upon wake-up. Any Reset, other than POR, will set the Idle status bit. On a POR, the Idle bit is cleared. If Watchdog Timer is enabled, then the processor will wake-up from Idle mode upon WDT time-out. The Idle and WDTO status bits are both set. Unlike wake-up from Sleep, there are no time delays involved in wake-up from Idle.
21.7
Device Configuration Registers
All Resets will wake-up the processor from Sleep mode. Any Reset, other than POR, will set the Sleep status bit. In a POR, the Sleep bit is cleared. If Watchdog Timer is enabled, then the processor will wake-up from Sleep mode upon WDT time-out. The Sleep and WDTO status bits are both set.
The configuration bits in each device configuration register specify some of the device modes and are programmed by a device programmer, or by using the InCircuit Serial ProgrammingTM (ICSPTM) feature of the device. Each device configuration register is a 24-bit register, but only the lower 16 bits of each register are used to hold configuration data. There are four device configuration registers available to the user: 1. 2. 3. 4. FOSc (0xF80000): Oscillator Configuration Register FWDT (0xF80002): Watchdog Timer Configuration Register FBORPOR (0xF80004): BOR and POR Configuration Register FGS (0xF8000A): General Code Segment Configuration Register
21.6.2
IDLE MODE
In Idle mode, the clock to the CPU is shutdown while peripherals keep running. Unlike Sleep mode, the clock source remains active. Several peripherals have a control bit in each module, that allows them to operate during Idle. LPRC fail-safe clock remains active if clock failure detect is enabled. The processor wakes up from Idle if at least one of the following conditions is true: * on any interrupt that is individually enabled (IE bit is `1') and meets the required priority level * on any Reset (POR, BOR, MCLR) * on WDT time-out Upon wake-up from Idle mode, the clock is re-applied to the CPU and instruction execution begins immediately, starting with the instruction following the PWRSAV instruction.
The placement of the configuration bits is automatically handled when you select the device in your device programmer. The desired state of the configuration bits may be specified in the source code (dependent on the language tool used), or through the programming interface. After the device has been programmed, the application software may read the configuration bit values through the table read instructions. For additional information, please refer to the programming specifications of the device. Note: If the code protection configuration fuse bits (FGS and FGS) have been programmed, an erase of the entire code-protected device is only possible at voltages VDD 4.5V.

21.8 In-Circuit Debugger
When MPLAB ICD2 is selected as a Debugger, the In-Circuit Debugging functionality is enabled. This function allows simple debugging functions when used with MPLAB IDE. When the device has this feature enabled, some of the resources are not available for general use. These resources include the first 80 bytes of Data RAM and two I/O pins. One of four pairs of Debug I/O pins may be selected by the user using configuration options in MPLAB IDE. These pin pairs are named EMUD/EMUC, EMUD1/ EMUC1, EMUD2/EMUC2 and MUD3/EMUC3. In each case, the selected EMUD pin is the Emulation/ Debug Data line, and the EMUC pin is the Emulation/ Debug Clock line. These pins will interface to the MPLAB ICD 2 module available from Microchip. The selected pair of Debug I/O pins is used by MPLAB ICD 2 to send commands and receive responses, as well as to send and receive data. To use the In-Circuit Debugger function of the device, the design must implement ICSP connections to MCLR, VDD, VSS, PGC, PGD and the selected EMUDx/EMUCx pin pair. This gives rise to two possibilities: 1. If EMUD/EMUC is selected as the Debug I/O pin pair, then only a 5-pin interface is required, as the EMUD and EMUC pin functions are multiplexed with the PGD and PGC pin functions in all dsPIC30F devices. If EMUD1/EMUC1, EMUD2/EMUC2 or EMUD3/ EMUC3 is selected as the Debug I/O pin pair, then a 7-pin interface is required, as the EMUDx/EMUCx pin functions (x = 1, 2 or 3) are not multiplexed with the PGD and PGC pin functions.

22.0 INSTRUCTION SET SUMMARY
Most bit oriented instructions (including simple rotate/ shift instructions) have two operands: * The W register (with or without an address modifier) or file register (specified by the value of `Ws' or `f') * The bit in the W register or file register (specified by a literal value, or indirectly by the contents of register `Wb') The literal instructions that involve data movement may use some of the following operands: * A literal value to be loaded into a W register or file register (specified by the value of `k') * The W register or file register where the literal value is to be loaded (specified by `Wb' or `f') However, literal instructions that involve arithmetic or logical operations use some of the following operands: * The first source operand, which is a register `Wb' without any address modifier * The second source operand, which is a literal value * The destination of the result (only if not the same as the first source operand), which is typically a register `Wd' with or without an address modifier The MAC class of DSP instructions may use some of the following operands: * The accumulator (A or B) to be used (required operand) * The W registers to be used as the two operands * The X and Y address space pre-fetch operations * The X and Y address space pre-fetch destinations * The accumulator write back destination The other DSP instructions do not involve any multiplication, and may include: * The accumulator to be used (required) * The source or destination operand (designated as Wso or Wdo, respectively) with or without an address modifier * The amount of shift, specified by a W register `Wn' or a literal value The control instructions may use some of the following operands: * A program memory address * The mode of the Table Read and Table Write instructions All instructions are a single word, except for certain double-word instructions, which were made doubleword instructions so that all the required information is available in these 48-bits. In the second word, the 8 MSb's are 0's. If this second word is executed as an instruction (by itself), it will execute as a NOP.
Note: This data sheet summarizes features of this group of dsPIC30F devices and is not intended to be a complete reference source. For more information on the CPU, peripherals, register descriptions and general device functionality, refer to the dsPIC30F Family Reference Manual (DS70046). For more information on the device instruction set and programming, refer to the dsPIC30F Programmer's Reference Manual (DS70030).
The dsPIC30F instruction set adds many enhancements to the previous PICmicro(R) instruction sets, while maintaining an easy migration from PICmicro instruction sets. Most instructions are a single program memory word (24-bits). Only three instructions require two program memory locations. Each single-word instruction is a 24-bit word divided into an 8-bit opcode which specifies the instruction type, and one or more operands which further specify the operation of the instruction. The instruction set is highly orthogonal and is grouped into five basic categories: * * * * * Word or byte-oriented operations Bit-oriented operations Literal operations DSP operations Control operations
Table 22-1 shows the general symbols used in describing the instructions. The dsPIC30F instruction set summary in Table 22-2 lists all the instructions along with the status flags affected by each instruction. Most word or byte-oriented W register instructions (including barrel shift instructions) have three operands: * The first source operand, which is typically a register `Wb' without any address modifier * The second source operand, which is typically a register `Ws' with or without an address modifier * The destination of the result, which is typically a register `Wd' with or without an address modifier However, word or byte-oriented file register instructions have two operands: * The file register specified by the value `f' * The destination, which could either be the file register `f' or the W0 register, which is denoted as `WREG'

dsPIC30F6010
Most single word instructions are executed in a single instruction cycle, unless a conditional test is true or the program counter is changed as a result of the instruction. In these cases, the execution takes two instruction cycles with the additional instruction cycle(s) executed as a NOP. Notable exceptions are the BRA (unconditional/computed branch), indirect CALL/GOTO, all Table Reads and Writes and RETURN/RETFIE instructions, which are single word instructions, but take two or three cycles. Certain instructions that involve skipping over the subsequent instruction, require either two or three cycles if the skip is performed, depending on whether the instruction being skipped is a single word or two-word instruction. Moreover, double-word moves require two cycles. The double-word instructions execute in two instruction cycles. Note: For more details on the instruction set, refer to the dsPIC30F Programmer's Reference Manual (DS70030).

24.0 ELECTRICAL CHARACTERISTICS
This section provides an overview of dsPIC30F electrical characteristics. Additional information will be provided in future revisions of this document as it becomes available. For detailed information about the dsPIC30F architecture and core, refer to dsPIC30F Family Reference Manual (DS70046). Absolute maximum ratings for the dsPIC30F family are listed below. Exposure to these maximum rating conditions for extended periods may affect device reliability. Functional operation of the device at these or any other conditions above the parameters indicated in the operation listings of this specification is not implied.

Thus, a series resistor of 50-100 should be used when applying a "low" level to the MCLR/VPP pin, rather than pulling this pin directly to VSS. 2: Maximum allowable current is a function of device maximum power dissipation. See Table 24-4. Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

Data in "Typ" column is at 5V, 25C unless otherwise stated. Parameters are for design guidance only and are not tested. These parameters are characterized but not tested in manufacturing. In RC oscillator configuration, the OSC1/CLKl pin is a Schmitt Trigger input. It is not recommended that the dsPIC30F device be driven with an external clock while in RC mode. The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified levels represent normal operating conditions. Higher leakage current may be measured at different input voltages. Negative current is defined as current sourced by the pin.

Data in "Typ" column is at 5V, 25C unless otherwise stated. Parameters are for design guidance only and are not tested. These parameters are characterized but not tested in manufacturing. Instruction cycle period (TCY) equals four times the input oscillator time-base period. All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at "min." values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the "Max." cycle time limit is "DC" (no clock) for all devices. Measurements are taken in EC or ERC modes. The CLKOUT signal is measured on the OSC2 pin. CLKOUT is low for the Q1-Q2 period (1/2 TCY) and high for the Q3-Q4 period (1/2 TCY).
