When "L" level is applied to this pin, the microcomputer enters the reset state. These are pins of main-clock generating circuit. Connect a ceramic resonator or a quartz crystal oscillator between XIN and XOUT. When an external clock is used, the clock source should be connected to the XIN pin, and the XOUT pin should be left open. _ When output level of E signal is "L", data/instruction read or data write is performed. This pin determines whether the external data bus has an 8-bit width or a 16-bit width. The data bus has a 16-bit width when "L" signal is input and an 8-bit width when "H" signal is input. Power source input pin for the A-D converter. Externally connect AVcc to Vcc and AVss to Vss. This is reference voltage input pin for the A-D converter. Address (A0 - A7) is output. When the BYTE pin is set to "L" and external data bus has a 16-bit width, high-order data (D8 - D15) is input/output or an address (A8 - A15) is output. When the BYTE pin is "H" and an external data bus has an 8-bit width, only address (A8 - A15) is output. Low-order data (D0 - D7) is input/output or an address (A16 - A23) is output. Input Output I/O I/O Output Output Output Output Input Input Output I/O I/O I/O "H" indicates the read status and "L" indicates the write status. "L" is output when an odd-numbered address is accessed. This is used to retrieve only the address from address and data multiplex signal. This outputs "L" level when the microcomputer enters hold state after a hold request is accepted. This is an input pin for HOLD request signal. The microcomputer enters into hold state while this signal is "L". ___ This is an input pin for RDY signal. The microcomputer enters into ready state while this signal is "L". This pin outputs the clock 1. These pins become a 5-bit I/O port. An I/O direction register is available so that each pin can be programmed for input or output. These ports are in the input mode when reset. In addition to having the same functions as port P4, these__ also function as I/O pins for timers pins __ A0 to A3 and input pins for key input interrupt input (KI1 - KI3). In addition to having the same functions as port ___these pins also function as I/O pins for timer P4, ___ A4, input pins for external interrupt input (INT0 - INT2) and input pins for timers B0 to B2. P67 also functions as sub-clock SUB output pin. In addition to having the same functions as port P4, these pins function as input pins for A-D converter. P72 to P75 also function as I/O pins for UART2. Additionally, P76 and P77 have the function as the output pin (XCOUT) and the input pin (XCIN) of the sub-clock (32 kHz) oscillation circuit, respectively. When P76 and P77 are used as the XCOUT and XCIN pins, connect a resonator or an oscillator between the both. In addition to having the same functions as port P4, these pins also function as I/O pins for UART 0 and UART 1. ____ ____ RDY ledge output Hold request input Ready input P42/ 1 P43 - P47 P50 - P57 P60 - P67 Clock output I/O port P4 I/O port P5 I/O port P6 P70 - P77 I/O port P7 I/O P80 - P87 I/O port P8 I/O 4 MITSUBISHI MICROCOMPUTERS New pro t duc M37733S4LHP 16-BIT CMOS MICROCOMPUTER BASIC FUNCTION BLOCKS The M37733S4LHP has the same functions as the M37733MHBXXXFP except for the following : (1) The memory map is different. (2) The processor mode is different. (3) The reset circuit is different. (4) Pulse output port mode of timer A is available. (5) The function of ROM area modification is not available. MEMORY The memory map is shown in Figure 1. The address space has a capacity of 16 Mbytes and is allocated to addresses from 016 to FFFFFF16. The address space is divided by 64-Kbyte unit called bank. The banks are numbered from 016 to FF16. Built-in RAM and control registers for internal peripheral devices are assigned to bank 016. Addresses FFD616 to FFFF16 are the RESET and interrupt vector addresses and contain the interrupt vectors. Use ROM for memory of this address. The 2048-byte area allocated to addresses from 8016 to 87F16 is the built-in RAM. In addition to storing data, the RAM is used as stack during a subroutine call or interrupts. Peripheral devices such as I/O ports, A-D converter, serial I/O, timer, and interrupt control registers are allocated to addresses from 016 to 7F16. A 256-byte direct page area can be allocated anywhere in bank 016 by using the direct page register (DPR). In the direct page addressing mode, the memory in the direct page area can be accessed with two words. Hence program steps can be reduced. 00000016 Bank 016 00FFFF16 01000016 00000016 00007F16 00008016 00000016 Internal peripheral devices control registers refer to Fig. 2 for detail information Internal RAM 2048 bytes 00007F16 Bank 116 00FFD616 01FFFF16 ******************* Interrupt vector table A-D/UART2 trans./rece.

Fig. 2 Location of internal peripheral devices and interrupt control registers 6 MITSUBISHI MICROCOMPUTERS New pro t duc M37733S4LHP 16-BIT CMOS MICROCOMPUTER Pulse output port mode The pulse motor drive waveform can be output by using plural internal timer A. Figure 3 shows a block diagram for pulse output port mode. In the pulse output port mode, two pairs of four-bit pulse output ports are used. Whether using pulse output port or not can be selected by waveform output selection bit (bit 0, bit 1) of waveform output mode register (6216 address) shown in Figure 4. When bit 0 of waveform output selection bit is set to "1", RTP10, RTP11, RTP12, and RTP13 are used as pulse output ports, and when bit 1 of waveform output selection bit is set to "1", RTP00, RTP01, RTP02, and RTP03 are used as pulse output ports. When bits 1 and 0 of waveform output selection bit are set to "1", RTP10, RTP11, RTP12, and RTP13, and RTP00, RTP01, RTP02, and RTP03 are used as pulse output ports. The ports not used as pulse output ports can be used as normal parallel ports, timer input/output or key input interrupt input. In the pulse output port mode, set timers A0 and A2 to timer mode as timers A0 and A2 are used. Figure 5 shows the bit configuration of timer A0, A2 mode registers in pulse output port mode. Data can be set in each bit of the pulse output data register corresponding to four ports selected as pulse output ports. Figure 6 shows the bit configuration of the pulse output data register. The contents of the pulse output data register 1 (low-order four bits of 1C16 address) corresponding to RTP10, RTP11, RTP12, and RTP13 is output to the ports each time the counter of timer A2 becomes 000016. The contents of the pulse output data register 0 (low-order four bits of 1D16 address) corresponding to RTP00, RTP01, RTP02, and RTP03 is output to the ports each time the counter of timer A0 becomes 000016. Figure 7 shows example of waveforms in pulse output port mode. When "0" is written to a specified bit of the pulse output data register, "L" level is output to the corresponding pulse output port when the counter of corresponding timer becomes 000016, and when "1" is written, "H" level is output to the pulse output port. Pulse width modulation can be applied to each pulse output port. Since pulse width modulation involves the use of timers A1 and A3, activate these timers in pulse width modulation mode. 4 Pulse width modulation selection bit (Bit 4, 5 of 6216 address) 5 Pulse width modulation output by timer A3 Pulse width modulation output by timer A1 Timer A2 Pulse output data register 1 (1C16 address) D3 D2 D1 DTQ D D D Q Q Q RTP13 (P57) RTP12 (P56) RTP11 (P55) RTP10 (P54) Data bus (even) Data bus (odd) D0 D11 D10 D9 D8 Pulse output data register 0 (1D16 address) Timer A0 D D D D T Q Q Q Q RTP03 (P53) RTP02 (P52) RTP01 (P51) RTP00 (P50) Polarity selection bit (Bit 3 of 6216 address) Fig. 3 Block diagram for pulse output port mode 7 MITSUBISHI MICROCOMPUTERS New pro t duc M37733S4LHP 16-BIT CMOS MICROCOMPUTER RTP10, RTP11, RTP12, and RTP13 are applied pulse width modulation by timer A3 by setting the pulse width modulation selection bit by timer A3 (bit 5) of the waveform output mode register to "1". RTP00, RTP01, RTP02, and RTP03 are applied pulse width modulation by timer A1 by setting the pulse width modulation selection bit by timer A1 (bit 4) of the waveform output mode register to "1". The contents of the pulse output data register 0 can be reversed and output to pulse output ports RTP00, RTP01, RTP02, and RTP03 by the polarity selection bit (bit 3) of the waveform output mode register. When the polarity selection bit is "0", the contents of the pulse output data register 0 is output unchangeably, and when "1", the contents of the pulse output data register 0 is reversed and output. When pulse width modulation is applied, likewise the polarity reverse to pulse width modulation can be selected by the polarity selection bit. 76543210 00X1 00 Address Timer A0 mode register 5616 Timer A2 mode register 5816 Always "100" in pulse output port mode Not used in pulse output port mode Always "00" in pulse output port mode Clock source selection bit 0 0 : Select f2 0 1 : Select f16 1 0 : Select f64 1 1 : Select f512 76543210 0 Fig. 5 Timer A0, A2 mode register bit configuration in pulse output port mode Address Weveform output mode register 6216 Weveform output selection bit 0 0 : Parallel port 0 1 : RTP1 selected 1 0 : RTP0 selected 1 1 : RTP1 and RTP0 selected Polarity selection bit 0 : Positive polarity 1 : Negative polarity Pulse width modulation selection bit by timer A1 0 : Not modulated 1 : Modulated Pulse width modulation selection bit by timer A3 0 : Not modulated 1 : Modulated Always "0" 76543210 Address Pulse output data register 0 1D16 RTP00 output data RTP01 output data RTP02 output data RTP03 output data 76543210 Address Pulse output data register 1 1C16 RTP10 output data Fig. 4 Waveform output mode register bit configuration RTP11 output data RTP12 output data RTP13 output data Fig. 6 Pulse output data register bit configuration 8 MITSUBISHI MICROCOMPUTERS New pro t duc M37733S4LHP 16-BIT CMOS MICROCOMPUTER Example of pulse output port (RTP10 - RTP13) Output signal at each time when timer A2 becomes 000016 RTP13 (P57) RTP12 (P56) RTP11 (P55) RTP10 (P54) Example of pulse output port (RTP10 - RTP13) when pulse width modulation is applied by timer A3.

Figure 9 shows functions of P00/A0 to P47 pins in each mode. The external memory area also changes when the mode changes. Figure 10 shows the memory map for each mode. The accessing of the external memory is affected by the BYTE pin, the bit 2 (wait bit) of processor mode register 0, and bit 0 (wait selection bit) of processor mode register 1. * BYTE pin When accessing the external memory, the level of the BYTE pin is used to determine whether to use the data bus as 8-bit width or 16bit width. The data bus width is 8 bits when the level of the BYTE pin is "H", and P20/A16/D0 to P27/A23/D7 pins become the data I/O pins. The data bus width is 16 bits when the level of the BYTE pin is "L", and both P20/A16/D0 to P27/A23/D7 pins and P10/A8/D8 to P17/A15/ D15 pins become the data I/O pins.

The access time is extended in two ways and this is selected with bit 0 (wait selection bit) of processor mode register 1 (address 5F16). When this bit is "1", the access time is 1.5 times compared to that for no wait. When this bit is "0", the access time is twice compared to that for no wait. At reset, the wait bit and the wait selection bit are "0". The accessing of internal memory area is performed in no wait mode regardless of the wait bit. The processor modes are described below. Internal clock Ai/Dj Address Data Address Data Wait bit "1" (No wait) E ALE Access time Ai/Dj Address Data Address Data Wait bit "0" (Wait 1) E ALE Access time Ai/Dj Address Data Address Microprocessor mode 0016 SFR 8016 RAM 87F16 Evaluation chip mode 216 A16 C16 SFR 8016 RAM 87F16 Wait bit "0" (Wait 0) E ALE Access time Fig. 11 Relationship between wait bit, wait selection bit, and access time (1) Microprocessor mode [10] Microprocessor mode is entered by connecting the CNVss pin to Vcc and starting from reset. _ _ Signal E is output from pin E and is "L" during the data/instruction code read or data write term. When the internal memory area is read _ or written, E can be fixed to "H" by setting the signal output disable selection bit (bit 6 of oscillation circuit control register 0) to "1". P00/A0 to P07/A7 pins become address output pins. P10/A8/D8 to P17/A15/D15 pins have two functions depending on the level of the BYTE pin. When the BYTE pin level is "L", P10/A8/D8 to P17/A15/D15 pins function _ as an address output pin while E is "H" and as an odd address data _ I/O pin while E is "L". However, if an internal memory is read, external _ data is ignored while E is "L". When the BYTE pin level is "H", P10/A8/D8 to P17/A15/D15 pins function as an address output pin. When the BYTE pin level is "L", P20/A16/D0 to P27/A23/D7 pins function _ as an address output pin while E is "H" and as an even address data _ I/O pin while E is "L". However, if an internal memory is read, external _ data is ignored while E is "L". _ R/W is a read /write signal which indicates a read when it is "H" and a write when it is "L". ___ BHE is a byte high enable signal which indicates that an odd address is accessed when it is "L". Therefore, two bytes at even and odd addresses are accessed ___ simultaneously if address A0 is "L" and BHE is "L". ALE is an address latch enable signal used to latch the address signal from a multiplexed signal of address and data. The latch is transparent while ALE is "H" to let the address signal pass through and held while ALE is "L". FFFFFF16 FFFFFF16 The shaded area is the external memory area. Fig. 10 External memory area for each processor mode 12 MITSUBISHI MICROCOMPUTERS New ____ pr ct odu M37733S4LHP 16-BIT CMOS MICROCOMPUTER HLDA is a hold acknowledge signal and is used to notify externally ____ when the microcomputer receives HOLD input and enters hold state. ____ HOLD is a hold request signal. It is an input signal used to put the ____ microcomputer in hold state. HOLD input is accepted when the internal clock falls from "H" level to "L" level while the bus is not used. P00/A0 to P07/A7 pins, P10/A8/D8 to P17/A15/D15 pins, P20/A16/D0 to _ ___ P27/A23/D7 pins, P30/R/W pin, and P31/BHE pin are floating while the microcomputer stays in hold state. These pins are floating after one ____ cycle of the internal clock later than HLDA signal changes to "L" level. At the removing of hold state, these ports are removed from ____ floating state after one cycle of internal clock later than HLDA signal changes to "H" level. ___ RDY is a ready signal. If this signal goes "L", the internal clock ___ stops at "L". RDY is used when slow external memory is attached. P42/ 1 pin is an output pin for clock 1 . The 1 output is ___ independent of RDY and does not stop even when internal clock ___ stops because of "L" input to the RDY pin. As shown in Table 2, 1 output can also be stopped with the signal output disable selection bit "1". In this case, write "1" to the port P42 direction register. (2) Evaluation chip mode [11] Evaluation chip mode is entered by applying voltage twice the VCC voltage to the CNVSS pin. This mode is normally used for evaluation tools. _ _ ___ ____ The functions of E, P00/A0 to P07/A7 pins, R/W, BHE, ALE, and HLDA are the same as those in microprocessor mode. P10/A8/D8 to P17/A15/D15 pins function as address output pins while _ _ E is "H" and as data I/O pin of odd addresses while E is "L" regardless of the BYTE pin level. However, if an internal memory is read, external _ data is ignored while E is "L". P20/A16/D0 to P27/A23/D7 pins function _ as address output pins while E is "H" and as data I/O pin of even _ addresses while E is "L" when the BYTE pin level is "L". However, if _ an internal memory is read, external data is ignored while E is "L". When the BYTE pin level is "H" or 2*VCC, port P2 functions as an _ address output pin while E is "H" and as data I/O pin of even and odd _ addresses while E is "L". However, if an internal memory is read, _ external data is ignored while E is "L". Port P4 and its data direction which are located at address 0A16 and 0C16 are treated differently in evaluation chip mode. When these addresses are accessed, the data bus width is treated as 16 bits regardless of the BYTE pin level, and the access cycle is treated as internal memory regardless of the wait bit. ____ ___ The functions of HOLD and RDY are the same as those in microprocessor mode. Clock 1 from P42/ 1 pin is always output regardless of signal output disable selection bit. Ports P43 to P46 become MX, QCL, VDA, and VPA output pins ___ respectively. Port P47 becomes the DBC input pin. The MX signal normally contents of flag m, but the contents of flag x is output if the CPU is using flag x. QCL is the queue buffer clear signal. It becomes "H" when the instruction queue buffer is cleared, for example, when a jump instruction is executed. VDA is the valid data address signal. It becomes "H" while the CPU is reading data from data buffer or writing data to data buffer. It also becomes "H" when the first byte of the instruction (operation code) is read from the instruction queue buffer. VPA is the valid program address signal. It becomes "H" while the CPU is reading an instruction code from the instruction queue buffer. ___ DBC is the debug control signal and is used for debugging. Table 1 shows the relationship between the CNVSS pin input levels and processor modes. Table 1.

Program execution starts at the address formed by setting address A23 - A16 to 0016, A15 - A8 to the contents of address FFFF16, and A7 - A0 to the contents of address FFFE16. Figure 12 shows the status of the internal registers during reset. Figure 13 shows an example of a reset circuit. If the stabilized clock is input from the external to the main-clock oscillation circuit, the reset input voltage must be 0.55 V or less when the power source voltage reaches 2.7 V. If a resonator/oscillator is connected to the main-clock oscillation circuit, change the reset input voltage from "L" to "H" after the main-clock oscillation is fully stabilized.
