xc164d derivatives functional description data sheet 24 v1.2, 2006-08 3.4 interrupt system with an interrupt response time of typically 8 cpu clocks (in case of internal program execution), the xc164d is ca pable of reacting very fast to the occurrence of non- deterministic events. the architecture of the xc164d supports several mechanisms fo r fast and flexible response to service requests that can be generated from various sources internal or external to the microcontrol ler. any of these interrupt requests can be programmed to being serviced by the interrupt controller or by the peripheral event controller (pec). in contrast to a standard interrupt service where the current program execution is suspended and a branch to th e interrupt vector table is performed, just one cycle is ?stolen? from the current cpu activity to perform a pec serv ice. a pec service implies a single byte or word data tran sfer between any two memory locations with an additional increment of either the pec so urce, or the destination pointer , or both. an individual pec transfer counter is implicitly decremented for each pec service except when performing in the continuous transfer m ode. when this counter reache s zero, a standard interrupt is performed to the corresponding source related vector loca tion. pec services are very well suited, for example, for supporting the transmission or reception of blocks of data. the xc164d has 8 pec channel s each of which offers such fast interrupt-driven data transfer capabilities. a separate control register wh ich contains an interrupt requ est flag, an interrupt enable flag and an interrupt priority bi tfield exists for each of the po ssible interrupt nodes. via its related register, each node ca n be programmed to one of sixt een interrupt priority levels. once having been accepted by the cpu, an interrupt servic e can only be interrupted by a higher prioritized service request. for th e standard interrupt pr ocessing, each of the possible interrupt nodes has a dedicated vector location. fast external interrupt inputs are provided to service external interrupts with high precision requirements. these fast in terrupt inputs featur e programmable edge detection (rising edge, fall ing edge, or both edges). software interrupts are supported by means of the ?trap? instruction in combination with an individual trap (interrupt) number. table 4 shows all of the possibl e xc164d interrupt source s and the corresponding hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers. note: interrupt nodes which are not assig ned to peripherals (u nassigned nodes), may be used to generate softwa re controlled interrupt requests by setting the respective interrupt request bit (xir).

xc164d derivatives functional description data sheet 29 v1.2, 2006-08 3.5 on-chip debug support (ocds) the on-chip debug support system provides a broad range of debug and emulation features built into the xc1 64d. the user software running on the xc164d can thus be debugged within the target system environment. the ocds is controlled by an external debugging device via the debug interface, consisting of the ieee-1149-c onforming jtag port and a br eak interface. the debugger controls the ocds via a set of dedicated re gisters accessible via the jtag interface. additionally, the ocds system can be controlled by the cpu, e.g. by a monitor program. an injection interface allows the execution of ocds-generated instructions by the cpu. multiple breakpoints can be triggered by on-chip hardware, by software, or by an external trigger input. single stepping is sup ported as well as the injection of arbitrary instructions and read/write a ccess to the complete internal address space. a breakpoint trigger can be answered with a cpu-halt, a monitor call, a data transfer, or/and the activation of an external signal. tracing data can be obtained via the jtag in terface or via the exte rnal bus interface for increased performance. the debug interface uses a set of 6 interface sign als (4 jtag lines, 2 break lines) to communicate with external ci rcuitry. these interface sign als are realized as alternate functions on port 3 pins. complete system emulation is supported by the new em ulation technology (net) interface. 3.6 capture/compare units (capcom1/2) the capcom units support generation and control of timing sequences on up to 32 channels with a maximum re solution of 1 system clock cy cle (8 cycles in staggered mode). the capcom units are typically us ed to handle high sp eed i/o tasks such as pulse and waveform generation, pulse width modulation (pmw ), digital to analog (d/a) conversion, software timing , or time recording relati ve to external events. four 16-bit timers (t0/t1, t7/t8) with reload registers prov ide two independent time bases for each capture/ compare register array. the input clock for the timers is programmable to several prescaled values of the internal system clock, or may be derived from an over flow/underflow of timer t6 in module gpt2. this provides a wide range of variation for th e timer period and re solution and allows precise adjustments to the appl ication specific requirements . in addition, external count inputs for capcom timers t0 and t7 allow event schedu ling for the capture/compare registers relative to external events. both of the two capture/compare regist er arrays contain 16 dual purpose capture/compare registers, each of which may be individually allocated to either capcom timer t0 or t1 (t7 or t8, resp ectively), and programmed for capture or

xc164d derivatives functional description data sheet 33 v1.2, 2006-08 3.8 general purpose timer unit (gpt12e) the gpt12e unit represents a very flexible multifunctional timer/c ounter structure which may be used for many different time rela ted tasks such as event timing and counting, pulse width and duty cycle me asurements, pulse generation , or pulse multiplication. the gpt12e unit incorporates five 16-bit timers which are organ ized in two separate modules, gpt1 and gpt2. each timer in each module may operate independently in a number of different modes, or may be co ncatenated with another timer of the same module. each of the three ti mers t2, t3, t4 of module gpt1 can be configured individually for one of four basic modes of operation, which are timer, gated timer, counter, and incremental interface mode. in timer mode, the in put clock for a timer is derived from the system clock, divided by a programmable prescaler, while counter mode allows a timer to be clocked in refe rence to external events. pulse width or duty cycle meas urement is supported in ga ted timer mode, where the operation of a timer is controlled by the ?gat e? level on an external input pin. for these purposes, each timer has one a ssociated port pin (txin) which serves as gate or clock input. the maximum reso lution of the timers in module gpt1 is 4 system clock cycles. the count direction (up/down ) for each timer is progra mmable by software or may additionally be altered dyna mically by an external sign al on a port pin (txeud) to facilitate e.g. position tracking. in incremental interface mode the gpt1 timers (t2, t3, t4) can be directly connected to the incremental posi tion sensor signals a and b via their respecti ve inputs txin and txeud. direction and count signals are intern ally derived from these two input signals, so the contents of the respec tive timer tx corresponds to the sensor position. the third position sensor signal top0 can be connected to an interrupt input. timer t3 has an output toggle latch (t3otl) which changes its state on each timer over- flow/underflow. the state of this latch ma y be output on pin t3out e.g. for time out monitoring of external hardware components. it may also be used internally to clock timers t2 and t4 for m easuring long time periods with high resolution. in addition to their basic op erating modes, timers t2 and t4 may be configured as reload or capture registers for timer t3. when used as capture or reload registers, timers t2 and t4 are stopped. the c ontents of timer t3 is captured into t2 or t4 in response to a signal at their associated input pins (txin). timer t3 is re loaded with the contents of t2 or t4 triggered either by an ex ternal signal or by a selectable state transition of its toggle latch t3otl. when both t2 and t4 are config ured to alternately reload t3 on opposite state transitions of t3otl with the low and high times of a pwm signal, this signal can be constantly generated with out software intervention.

xc164d derivatives functional description data sheet 35 v1.2, 2006-08 count direction (up/down) fo r each timer is programma ble by software or may additionally be altered dynamically by an external signal on a port pin (txeud). concatenation of the timers is supported via the output togg le latch (t6otl) of timer t6, which changes its state on ea ch timer overflow/underflow. the state of this latch may be used to clock timer t5, and/ or it may be output on pin t6out. the overflows/underflo ws of timer t6 can additi onally be used to clock the capcom1/2 timers, and to cause a re load from the ca prel register. the caprel register may capt ure the contents of timer t5 based on an external signal transition on the corresponding port pin (c apin), and timer t5 may optionally be cleared after the capture procedure. this allo ws the xc164d to measure absolute time differences or to perform pulse multip lication without so ftware overhead. the capture trigger (timer t5 to caprel) may also be ge nerated upon transitions of gpt1 timer t3?s inputs t3in and/or t3e ud. this is especially advantageous when t3 operates in incremental interface mode.

xc164d derivatives functional description data sheet 43 v1.2, 2006-08 3.13 watchdog timer the watchdog timer represen ts one of the fail-safe mechanisms which have been implemented to prevent the co ntroller from malfunctioning for longer periods of time. the watchdog timer is always enabled after a reset of th e chip, and can be disabled until the einit instruction ha s been executed (compatible mo de), or it can be disabled and enabled at any time by executing instructions diswdt and enwdt (enhanced mode). thus, the chip?s start-up procedure is always monitored. the software has to be designed to restart the watchd og timer before it overfl ows. if, due to hardware or software related failures, the software fails to do so, the watchdog timer overflows and generates an internal hardwa re reset and pulls the rstout pin low in order to allow external hardware comp onents to be reset. the watchdog timer is a 16-bit timer, cl ocked with the system clock divided by 2/4/128/256. the high by te of the watchdog ti mer register can be set to a prespecified reload value (stored in wdtrel) in order to allow further variation of the monitored time interval. each time it is serviced by the application software, the high byte of the watchdog timer is rel oaded and the low byte is cleared. thus, time intervals between 13 s and 419 ms can be m onitored (@ 40 mhz). the default watchdog timer interval after reset is 3.28 ms (@ 40 mhz).
xc164d derivatives functional description data sheet 44 v1.2, 2006-08 3.14 clock generation the clock generation unit uses a programma ble on-chip pll with multiple prescalers to generate the clock signals for the xc164d wi th high flexibility. the master clock f mc is the reference clock signal, and is used for twincan and is ou tput to the external system. the cpu clock f cpu and the system clock f sys are derived from the master clock either directly (1:1) or via a 2:1 prescaler ( f sys = f cpu = f mc / 2). see also section 4.3.1 . the on-chip oscillator can drive an external crystal or accepts an external clock signal. the oscillator clock fr equency can be multiplied by th e on-chip pll (by a programmable factor) or can be divided by a programmable prescaler factor. if the bypass mode is used (direct drive or prescaler) the pll ca n deliver an independent clock to monitor the clock sign al generated by the on-chip oscillator. this pll clock is independent from the xtal1 clock. when the expected o scillator clock transitions are missing the oscillator watchdog (owd) acti vates the pll unlock/ owd interrupt node and supplies the cpu with an emergency clock, the pll clock signal. under these circumstances the pll will osci llate with its basic frequency. the oscillator watchdog can be disabled by switching the pll o ff. this reduces power consumption, but also no in terrupt request will be gene rated in case of a missing oscillator clock. note: at the end of an external reset (ea = ?0?) the oscillator watchdog may be disabled via hardware by (ext ernally) pulling the rd line low upon a reset, similar to the standard reset configuration. 3.15 parallel ports the xc164d provides up to 79 i/o lines which are organized into six input/output ports and one input port. all port lines are bit- addressable, and all in put/output lines are individually (bit-wise) progra mmable as inputs or outputs via direction registers. the i/o ports are true bidirectional ports which are switched to high impedance state when configured as inpu ts. the output drivers of some i/o ports can be configured (pin by pin) for push/pull operation or open -drain operation via control registers. during the internal reset, all port pins are configured as inputs (except for pin rstout ). the edge characteristics (sh ape) and driver characteristi cs (output current) of the port drivers can be selected via registers poconx. the input threshold of some ports is select able (ttl or cmos like), where the special cmos like input threshold reduces noise se nsitivity due to the input hysteresis. the input threshold may be selected individually for each byte of the respective ports. all port lines have programmable alternate input or output func tions associated with them. all port lines that are not used for thes e alternate functions may be used as general purpose io lines.

xc164d derivatives functional description data sheet 46 v1.2, 2006-08 3.16 power management the xc164d provides several m eans to control the power it consumes either at a given time or averaged over a certain timespan . three mechanisms can be used (partly in parallel): ? power saving modes switch the xc164d into a spec ial operating mode (control via instructions). idle mode stops the cpu while the peripherals ca n continue to operate. sleep mode and power down mo de stop all clock signals a nd all operation (rtc may optionally continue running) . sleep mode can be termina ted by external interrupt signals. ? clock generation management controls the distribu tion and the frequency of internal and external clock signals. while th e clock signals for currently inactive parts of logic are disabled automa tically, the user can reduce the xc164d?s cpu clock frequency which drastically reduces the consumed power. external circuitry can be controlled via the programmable frequency output fout. ? peripheral management permits temporary disabling of peripheral modules (control via register syscon3). ea ch peripheral can separat ely be disabled/enabled. the on-chip rtc supports inte rmittent operation of the xc164d by generating cyclic wake-up signals. this offers full performance to quickly re act on action requests while the intermittent sleep phases greatly reduce the average power consumption of the system.

xc164d derivatives electrical parameters data sheet 58 v1.2, 2006-08 4.3 ac parameters 4.3.1 definition of internal timing the internal operation of th e xc164d is controlled by the internal master clock f mc . the master clock signal f mc can be generated from t he oscillator clock signal f osc via different mechanisms. the duration of master clock periods (tcms) and their variation (and also the derived external timing) depend on th e used mechanism to generate f mc . this influence must be r egarded when calculating t he timings for the xc164d. figure 14 generation mechanis ms for the master clock note: the example for pll operation shown in figure 14 refers to a pll factor of 1:4, the example for prescaler operation refers to a divider factor of 2:1. the used mechanism to generat e the master clock is sele cted by register pllcon. mct05555 phase locked loop operation (1:n) f osc direct clock drive (1:1) prescaler operation (n:1) f mc f osc f mc f osc f mc tcm tcm tcm
xc164d derivatives electrical parameters data sheet 59 v1.2, 2006-08 cpu and ebc are clocked wi th the cpu clock signal f cpu . the cpu clock can have the same frequency as the master clock ( f cpu = f mc ) or can be the master clock divided by two: f cpu = f mc / 2. this factor is selected by bit cpsy s in register syscon1. the specification of the extern al timing (ac charac teristics) depends on the period of the cpu clock, called ?tcp?. the other peripherals are supplied with th e system clock signal f sys which has the same frequency as the cpu clock signal f cpu . bypass operation when bypass operation is co nfigured (pllctrl = 0x b ) the master cloc k is derived from the internal oscillator (in put clock signal xtal1) thro ugh the input- and output- prescalers: f mc = f osc / ((pllidiv+1) (pllodiv+1)). if both divider factors are selected as ?1? (pllidiv = pllodiv = ?0?) the frequency of f mc directly follows the frequency of f osc so the high and low time of f mc is defined by the duty cycle of the input clock f osc . the lowest master clock frequency is achiev ed by selecting the ma ximum values for both divider factors: f mc = f osc / ((3 + 1) (14 + 1)) = f osc / 60. phase locked loop (pll) when pll operation is c onfigured (pllctrl = 11 b ) the on-chip phase locked loop is enabled and provides the mast er clock. the pll multiplies the input frequency by the factor f ( f mc = f osc f ) which results from the input divi der, the multiplication factor, and the output divider ( f = pllmul+1 / (pllidiv+1 pllodiv+1)). the pll circuit synchronizes the master clock to the input clock. this sync hronization is done smoothly, i.e. the master clock frequenc y does not change abruptly. due to this adaptation to t he input clock th e frequency of f mc is constantly adjusted so it is locked to f osc . the slight variati on causes a jitter of f mc which also affects the duration of individual tcms. the timing listed in t he ac characteristics re fers to tcps. because f cpu is derived from f mc , the timing must be calculated using th e minimum tcp possible under the respective circumstances. the actual minimum value for tcp depends on the jitter of the pll. as the pll is constantly adjusting its output frequency so it corresponds to the applied input frequency (crystal or oscillator) the rela tive deviation for periods of mo re than one tcp is lower than for one single tcp (see formula and figure 15 ). this is especially important fo r bus cycles using waitstates and e.g. for the operation of timers, serial interfac es, etc. for all slower operations and longer periods (e.g. pulse train
xc164d derivatives electrical parameters data sheet 60 v1.2, 2006-08 generation or measurement, lower baudrates, etc.) the deviation caused by the pll jitter is negligible. the value of the accumulat ed pll jitter depends on the number of consecutive vco output cycles within the respec tive timeframe. the vco outp ut clock is divided by the output prescaler (k = pl lodiv+1) to generate th e master clock signal f mc . therefore, the number of vco cycles can be represented as k n , where n is the number of consecutive f mc cycles (tcm). for a period of n tcm the accumulated pll jitter is defined by the deviation d n : d n [ns] = (1.5 + 6.32 n / f mc ); f mc in [mhz], n = number of consecutive tcms. so, for a period of 3 tcms @ 20 mhz and k = 12: d 3 = (1.5 + 6.32 3 / 20) = 2.448 ns. this formula is applicable for k n < 95. for longer periods the k n = 95 value can be used. this steady value c an be approximated by: d nmax [ns] = (1.5 + 600 / (k f mc )). figure 15 approximated accumulated pll jitter note: the bold lines indicate the minimum accumulated jitter which can be achieved by selecting the maximum possible output prescaler factor k. different frequency band s can be selected for the vco, so the operati on of the pll can be adjusted to a wide range of input and output frequencies: mcd05566 n 0 1 2 3 4 5 6 7 8 acc. jitter d n 0510 15 20 25 ns k = 15 k = 12 k = 10 k = 8 k = 6 k = 5 1 10 mhz 20 mhz 40 mhz

xc164d derivatives electrical parameters data sheet 62 v1.2, 2006-08 4.3.2 on-chip flash operation the xc164d?s flash module delivers data within a fixed access time (see table 15 ). accesses to the flash module are controlled by the pmi and take 1+ws clock cycles, where ws is the number of flash access waitstates sele cted via bitfield wsflash in register imbctrl. th e resulting duration of the ac cess phase must cover the access time t acc of the flash array. ther efore, the required flash waitstates depend on the available speed grade as well as on the actu al system frequency. note: the flash access wait states only affect non- sequential accesses. due to prefetching mechanisms, th e performance for sequenti al accesses (depending on the software structure) is only pa rtially influenced by waitstates. in typical applications, eliminating one waitstate incr eases the average performance by 5% ? 15%. example: for an operating frequency of 40 mhz (clock cycle = 25 ns), devices can be operated with 1 waitstate: ((1+1) 25 ns) 50 ns. table 16 indicates the interrelation of waitstates and system frequency. note: the maximum achievable system frequency is limited by the properties of the respective derivative, i. e. 40 mhz (or 20 mhz for xc164d-xxf20f devices). table 15 flash characteristics (operating conditions apply) parameter symbol limit values unit min. typ. max. flash module access time t acc cc ? ? 50 ns programming time per 128-byte block t pr cc ? 2 1) 1) programming and erase time depends on the syste m frequency. typical values are valid for 40 mhz. 5ms erase time per sector t er cc ? 200 1) 500 ms table 16 flash access waitstates required waitstates frequency range 0 ws (wsflash = 00 b ) f cpu 20 mhz 1 ws (wsflash = 01 b ) f cpu 40 mhz
