input pulses <10 ns. input pulses >100 ns safely pass the filter. the minimum duration for a safe recognition should be 100 ns + 2 cpu clock cycles. note: the reset duration must be sufficient to let the hardware configuration signals settle. external circuitry must guarantee low level at the rstin pin at least until both power supply voltages have reached the operating range. p20.12 2 io for details, please refer to the description of p20 . nmi 3 i non-maskable interrupt input. a high to low transition at this pin causes the cpu to vector to the nmi trap routine. when the pwrdn (power down) instruction is executed, the nmi pin must be low in order to force the xc164 into power down mode. if nmi is high, when pwrdn is executed, the part will continue to run in normal mode. if not used, pin nmi should be pulled high externally. p0h.0- p0h.3 4 7 io for details, please refer to the description of port0 . xc164 derivatives general device information data sheet 7 v2.1, 2003-06 p9

communication). the on-chip memory blocks (program code-memory and sram, dual-port ram, data sram) and the set of generic peripherals are connected to the cpu via separate buses. another bus, the lxbus, connects additional on-chip resoures as well as external resources (see figure 3 ). this bus structure enhances the overall syst em performance by enabling the concurrent operation of several subsystems of the xc164. the following block diagram gives an overvi ew of the different on-chip components and of the advanced, high bandwidth internal bus structure of the xc164. figure 3 block

the xc164 is configur ed in a von neumann architecture, which means that all internal and external resour ces, such as code memory, data memory, registers and i/o ports, are organized within the same linear address space. this common memory space includes 16 mbytes and is arranged as 256 segments of 64 kbytes each, where each segment consists of four data pages of 16 kbytes each. the entire memory space can be accessed by tewise or wordwise. portions of the on- chip dpram and the register spaces (e/sfr) have additionally been made directly bitaddressable. the internal data memory areas and the special function register areas (sfr and esfr) are mapped into segment 0, the system segment. the program management unit (pmu) handles all code fetches and, therefore, controls accesses to the program memories, su ch as flash memory, rom, and psram. the data management unit (dmu) handles all data transfers and, therefore, controls accesses to the dsram and the on-chip peripherals. both units (pmu and dmu) are connect ed via the high-speed system bus to exchange data. this is required if operands are read from program memory, code or data is written to the psram, code is fetched from external memory, or data is read from or written to external resources, includi ng peripherals on the lxbus (such as twincan). the system bus allows concurrent two-way communication for maximum transfer performance. 128 kbytes of on-chip flash memory or mask-programmable rom store code or constant data. the on-chip flash memory is organized as four 8-kbyte sectors, one 32-kbyte sector, and one 64-kbyte sector. each sector can be separately write protected 1) , erased and programmed (in blocks of 128 bytes). the complete flash or rom area can be read-protected. a passw ord sequence temporarily unlocks protected areas. the flash module comb ines very fast 64-bit one-cycle read accesses with protected and efficient writing algorithms for programming and erasing. thus, program execution out of the internal flash results in maximum performance. dynamic error correction provides extremely high read data security for all read accesses. programming typically takes 2 ms per 128-byte block (5 ms max.), erasing a sector typically takes 200 ms (500 ms max.). 2 kbytes of on-chip program sram (psram) are provided to store user code or data. the psram is accessed via the pmu and is therefore optimized for code fetches. 2 kbytes of on-chip data sram (dsram) are provided as a storage for general user data.the dsram is accessed via the dmu and is therefore optimized for data accesses. 2 kbytes of on-chip dual-port ram (dpram) are provided as a storage for user defined variables, for the system stack, general purpose register banks. a register bank can consist of up to 16 wordwide (r0 to r15) and/or bytewide (rl0, rh0, ?, rl7, rh7) 1) each two 8-kbyte sectors are combined for write-protection purposes. xc164 derivatives functional description data sheet 16 v2.1, 2003-06 so-called general purpose registers (gprs). the upper 256 bytes of the dpram are directly bitaddressable. when used by a gpr, any location in the dpram is bitaddressable. 1024 bytes (2 512 bytes) of the address space are rese rved for the special function register areas (sfr space and esfr space). sfrs are wordwide registers which are used for controlling and monitoring functions of the different on-chip units. unused sfr addresses are reserved for future members of the xc166 family. therefore, they should either not be accessed, or written with zeros, to ensure upward compatibility. in order to meet the needs of designs wher e more memory is required than is provided on chip, up to 12 mbytes (approximately, see table 3 ) of external ram and/or rom can be connected to the microcontroller. the external bus interface also provides access to external peripherals. table 3 xc164 memory map 1) 1) accesses to the shaded areas generate external bus accesses. address area start

formed by a particular on-chip external bus controller (ebc). it can be programmed either to single chip mode when no external memory is required, or to one of four different external memory access modes 1) , which are as follows: ? 16 24-bit addresses, 16-bit data, demultiplexed ? 16 24-bit addresses, 16-bit data, multiplexed ? 16 24-bit addresses, 8-bit data, multiplexed ? 16 24-bit addresses, 8-bit data, demultiplexed in the demultiplexed bus modes, addresses are output on port1 and data is input/ output on port0 or p0l, respectively. in the multiplexed bus modes both addresses and data use port0 for input/output. the high order address (segment) lines use port 4. the number of active segment address li nes is selectable, restricting the external address space to 8 mbytes 64 kbytes. this is required when interface lines are assigned to port 4. up to 4 external cs signals (3 windows plus default) can be generated in order to save external glue logic. external modules can directly be connected to the common address/ data bus and their individual select lines. important timing characteristics of the external bus interface have been made programmable (via registers tconcsx/fconcsx) to allow the user the adaption of a wide range of different types of memories and external peripherals. in addition, up to 4 independent address windows may be defined (via registers addrselx) which control the access to different resources with different bus characteristics. these address windows are arranged hierarchically where window 4 overrides window 3, and window 2 overrides window 1. all accesses to locations not covered by these 4 address windows are controlled by tconcs0/fconcs0. the currently active window can generate a chip select signal. the external bus timing is related to the rising edge of the reference clock output clkout. the external bus protocol is compatible with that of the standard c166 family. the ebc also controls accesses to resources connected to the on-chip lxbus. the lxbus is an internal representation of the external bus and allows accessing integrated peripherals and modules in the same way as external components. the twincan module is connected and accessed via the lxbus. 1) bus modes are switched dynamically if several address windows with different mode settings are used. xc164 derivatives functional description data sheet 18 v2.1, 2003-06 3.3 central processing unit (cpu) the main core of the cpu consists of a 5-stage execution pipeline with a 2-stage instruction-fetch pipeline, a 16-bit arithmetic and logic unit (alu), a 32-bit/40-bit multiply and accumulate unit (mac), a register-file providing three register banks, and dedicated sfrs. the alu features a multiply and divide unit, a bit-mask generator, and a barrel shifter. figure 4 cpu block diagram based on these hardware provisions, most of the xc164?s instructions can be executed in just one machine cycle which requires 25 ns at 40 mhz cpu clock. for example, shift and rotate instructions are always proc essed during one mach ine cycle independent of the number of bits to be shifted. also mu ltiplication and most mac instructions execute in one single cycle. all multiple-cycle instruct ions have been op timized so that they can be executed very fast as well: for example, a 32-/16-bit division is started within 4 cycles, while the remaining 15 cycles are executed in the background. another pipeline address data in data out csp ip cpucon1 cpucon2 fifo ifu idx0 idx1 qx1 qx0 qr1 qr0 sp spseg vecseg stkov stkun dpp0 dpp1 dpp3 dpp2 +/- +/-

optimization, the branch target prediction, allows eliminating the execution time of branch instructions if the prediction was correct. the cpu has a register context consisting of up to three register banks with 16 wordwide gprs each at its disposal. one of these register banks is physically allocated within the on-chip dpram area. a context pointer (cp) register determines the base address of the active register bank to be accessed by the cpu at any time. the number of register banks is only restricted by the availabl e internal ram space. for easy parameter passing, a register bank may overlap others. a system stack of up to 32 kwords is prov ided as a storage for temporary data. the system stack can be allocated to any location within the address space (preferably in the on-chip ram area), and it is accessed by the cpu via the stack pointer (sp) register. two separate sfrs, stkov and stkun, are implicitly compared against the stack pointer value upon each stack access for the detection of a stack overflow or underflow. the high performance offered by the hardware implementation of the cpu can efficiently be utilized by a programmer via the highly e fficient xc164 instruction set which includes the following instruction classes: ? standard arithmetic instructions ? dsp-oriented arithmetic instructions ? logical instructions ? boolean bit manipulation instructions ? compare and loop control instructions ? shift and rotate instructions ? prioritize instruction ? data movement instructions ? system stack instructions ? jump and call instructions ? return instructions ? system control instructions ? miscellaneous instructions the basic instruction length is either 2 or 4 bytes. possible operand types are bits, bytes and words. a variety of direct, indirect or immediate addressing modes are provided to specify the required operands. xc164 derivatives functional description data sheet 20 v2.1, 2003-06 3.4 interrupt system with an interrupt response time of typically 8 cpu clocks (in case of internal program execution), the xc164 is capable of reacting very fast to the occurrence of non- deterministic events. the architecture of the xc164 supports several mechanisms for fast and flexible response to service requests that can be generated from various sources internal or external to the microcontroller. any of th ese 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 servic e where the current program execution is suspended and a branch to the interrupt vector table is performed, just one cycle is ?stolen? from the current cpu activity to perform a pec service. a pec service implies a single byte or word data transfer between any two memory locations with an additional increment of either the pec source, 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 mode. when this counter reaches zero, a standard interrupt is performed to the corresponding source related vector location. pec services are very well suited, for example, for supporting the transmission or recepti on of blocks of data. the xc164 has 8 pec channels each of which offers such fast interrupt-driven data transfer capabilities. a separate control register which contains an interrupt request flag, an interrupt enable flag and an interrupt priority bitfield exists for each of the possible interrupt nodes. via its related register, each node can be programmed to one of sixteen interrupt priority levels. once having been accepted by the cpu, an interrupt service can only be interrupted by a higher prioritized service request. for t he standard interrupt processing, 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 interrupt inputs feature programmable edge detection (rising edge, falling 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 possible xc164 interrupt sources and the corresponding hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers. note: interrupt nodes which are not assigned to peripherals (unassigned nodes), may be used to generate software controlled interrupt requests by setting the respective interrupt request bit (xir). xc164 derivatives functional description data sheet 21 v2.1, 2003-06 table 4 xc164 interrupt nodes source of interrupt or pec service

sheet 25 v2.1, 2003-06 3.5 on-chip debug support (ocds) the on-chip debug support system prov ides a broad range of debug and emulation features built into the xc164. the user software running on the xc164 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-conforming jtag port and a break interface. the debugger controls the ocds via a set of dedicated registers 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 executio n 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 supported as well as the injection of arbitrary instructions and read/write access 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 interf ace or via the external bus interface for increased performance. the debug interface uses a set of 6 interf ace signals (4 jtag lines, 2 break lines) to communicate with external circuitry. these interface signals are realized as alternate functions on port 3 pins. complete system emulation is supported by the new emulation technology (net) interface. via this full-featured emulation in terface (including internal buses, control, status, and pad signals) the xc164 chip can be connected to a net carrier chip. the use of the xc164 production chip together with the carrier chip provides superior emulation behavior, because the emulation system shows ex actly the same functionality as the production chip (use of the identical silicon). xc164 derivatives functional description data sheet 26 v2.1, 2003-06 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 resolution of 1 system clock cycle (8 cycles in staggered mode). the capcom units are typically used to handle high speed i/o tasks such as pulse and waveform generation, pulse width modulation (pmw), digital to analog (d/a) conversion, software timing, or time re cording relative to external events. four 16-bit timers (t0/t1, t7/t8) with reload registers provide 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 time r t6 in module gpt2. this provides a wide range of variation for the timer period and resolution and allows precise adjustments to the application specif ic requirements. in addition, external count inputs for capcom timers t0 and t7 allow event scheduling 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, respectively), and programmed for capture or compare function. 12 registers of the capcom2 module have each one port pin associated with it which serves as an input pin for triggering the capt ure function, or as an output pin to indicate the occurrence of a compare event. table 6 compare modes (capcom1/2) compare modes function mode 0 interrupt-only compare mode; several compare

functional description data sheet 27 v2.1, 2003-06 when a capture/compare register has been selected for capture mode, the current contents of the allocated timer will be latc hed (?captured?) into the capture/compare register in response to an external event at the port pin which is associated with this register. in addition, a specific interrupt request for this capture/compare register is generated. either a positive, a negative, or both a positive and a negative external signal transition at the pin can be selected as the triggering event. the contents of all registers which have been selected for one of the five compare modes are continuously compared with the contents of the allocated timers. when a match occurs between the timer value and the value in a capture/compare register, specific actions will be ta ken based on the selected compare mode. figure 5 capcom1/2 unit block diagram mcb02143_x4.vsd mode control (c apture or compare) 2 n : 1 f sys tx input control capcom timer

capture/compare channels plus one independent 10-bit compare channel. in compare mode the capcom6 unit provides two output signals per channel which have inverted polarity and non-overlapping pulse transitions (deadtime control). the compare channel can generate a single pwm output signal and is further used to modulate the capture/compare output signals. in capture mode the contents of compare timer t12 is stored in the capture registers upon a signal transition at pins ccx. compare timers t12 (16-bit) and t13 (10-bit) are free running timers which are clocked by the prescaled system clock.

loading a value into the timer registers. xc164 derivatives functional description data sheet 29 v2.1, 2003-06 3.8 general purpose timer (gpt12e) unit the gpt12e unit represents a very flexible multifunctional timer/counter structure which may be used for many different time re lated tasks such as ev ent timing and counting, pulse width and duty cycle measurements, pul se generation, or pulse multiplication. the gpt12e unit incorporates five 16-bit timers which are organized in two separate modules, gpt1 and gpt2. each timer in each module may operate independently in a number of different modes, or may be c oncatenated with another timer of the same module. each of the three timers t2, t3, t4 of module gpt1 can be configured individually for one of four basic modes of operation, wh ich are timer, gated timer, counter, and incremental interface mode. in timer mode, the input 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 reference to external events. pulse width or duty cycle measurement is s upported in gated 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 associated port pin (txin) which serves as gate or clock input. the maximum resolution of the timers in module gpt1 is 4 system clock cycles. the count direction (up/down) for each timer is programmable by software or may additionally be altered dynamically by an external signal on a port pin (txeud) to facilitate e.g. position tracking. in incremental interface mode the gpt1 time rs (t2, t3, t4) can be directly connected to the incremental position sensor signals a and b via their respective inputs txin and txeud. direction and count signals are internally derived from these two input signals, so the contents of the respective 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 may 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 measuring long time periods with high resolution. in addition to their basic operating 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 contents of timer t3 is captured into t2 or t4 in response to a signal at their associated input pins (txin). timer t3 is reloaded with the contents of t2 or t4 triggered either by an external signal or by a selectable state transition of its toggle latch t3otl. when both t2 and t4 are configured 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 without software intervention. xc164 derivatives functional description data sheet 30 v2.1, 2003-06 figure 7 block diagram of gpt1 with its maximum resolution of 2 system clock cycles, the gpt2 module provides precise event control and time measuremen t. it includes two timers (t5, t6) and a capture/reload register (caprel). both timers can be clocked with an input clock which is derived from the cpu clock via a programmabl e prescaler or with external signals. the count direction (up/down) for each timer is programmable 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 toggle latch (t6otl) of timer t6, which changes its state on each 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/underflows of timer t6 can additionally be used to clock the capcom1/2 timers, and to cause a reload from the caprel register. the caprel register may capture the contents of timer t5 based on an external signal transition on the corresponding port pin (capin), and timer t5 may optionally be cleared t3 mode control 2 n : 1 f sys 2 n : 1 f sys t2 mode control gpt1 timer t2 reload capture 2 n : 1 f sys t4 mode control gpt1 timer t4 reload capture gpt1 timer t3 t3otl u/d

capture trigger (timer t5 to caprel) may also be generated upon transitions of gpt1 timer t3?s inputs t3in and/or t3eu d. this is especially advantageous when t3 operates in incremental interface

sheet 32 v2.1, 2003-06 3.9 real time clock the real time clock (rtc) module of the xc164 is directly clocked via a separate clock driver with the prescaled on-chip oscillator frequency ( f rtc = f osc / 32). it is therefore independent from the selected clock generation mode of the xc164. the rtc basically consists of a chain of divider blocks: a selectable 8:1 divider (on - off) the reloadable 16-bit timer t14 the 32-bit rtc timer block (accessible via registers rtch and rtcl), made of: ? a reloadable 10-bit timer ? a reloadable 6-bit timer ? a reloadable 6-bit timer ? a reloadable 10-bit timer all timers count up. each timer can gener ate an interrupt request. all requests are combined to a common node request. figure 9 rtc block diagram note: the registers associated with the rtc are not affected by a reset in order to maintain the correct system time even when intermediate re sets are executed. mcb04805_xc.vsd t14rel t14 t14-register cnt-register rel-register 10 bits 6 bits 6

the rtc module can be used for different purposes: system clock to determine the current time and date, optionally during idle mode, sleep mode, and power down mode cyclic time based interrupt, to provide a system time tick independent of cpu frequency and other resources, e.g. to wake up regularly from idle mode. 48-bit timer for long term measurements (maximum timespan is >100 years). alarm interrupt for wake-up on a defined time xc164 derivatives functional description data sheet 34 v2.1, 2003-06 3.10 a/d converter for analog signal measurement, a 10-bit a/d converter with 14 multiplexed input channels and a sample and hold circuit has been integrated on-chip. it uses the method of successive approximation. the sample time (for loading the capacitors) and the conversion time is programmable (in two modes) and can thus be adjusted to the external circuitry. the a/d converter can al so operate in 8-bit conversion mode, where the conversion time is further reduced. overrun error detection/protection is provided for the conversion result register (addat): either an interrupt request will be generated when the result of a previous conversion has not been read from the result register at the time the next conversion is complete, or the next conversion is suspended in such a case until the previous result has been read. for applications which require less analog input channels, the remaining channel inputs can be used as digital input port pins. the a/d converter of the xc164 supports fo ur different conversion modes. in the standard single channel conversion mode, the analog level on a specified channel is sampled once and converted to a digital result. in the single channel continuous mode, the analog level on a specified channel is repeatedly sampled and converted without software intervention. in the auto scan mode, the analog levels on a prespecified number of channels are sequentially sampled and converted. in the auto scan continuous mode, the prespecified channels are repeatedly sampled and converted. in addition, the conversion of a specific channel can be inserted (injected) into a running sequence without disturbing this sequence. this is called channel injection mode. the peripheral event controller (pec) may be used to automatically store the conversion results into a table in memory for later evaluation, without requiring the overhead of entering and exiting interr upt routines for each data transfer. after each reset and also during normal operation the adc automatically performs calibration cycles. this automatic self-calibration constantly adjusts the converter to changing operating conditions (e.g. temperatur e) and compensates process variations. these calibration cycles are part of the conver sion cycle, so they do not affect the normal operation of the a/d converter. in order to decouple analog inputs from digital noise and to avoid input trigger noise those pins used for analog input can be disco nnected from the digital io or input stages under software control. this can be selected for each pin separately via register p5didis (port 5 digital input disable). the auto-power-down feature of the a/d c onverter minimizes the power consumption when no conversion is in progress. xc164 derivatives functional description data sheet 35 v2.1, 2003-06 3.11 asynchronous/synchronous serial interfaces (asc0/asc1) the asynchronous/synchronous serial interfaces asc0/asc1 (usarts) provide serial communication with other microcontrollers, pr ocessors, terminals or external peripheral components. they are upward compatible with the serial ports of the infineon 8-bit microcontroller families and support full-duplex asynchronous communication and half- duplex synchronous communication. a dedicated baud rate generator with a fractional divider precisely generates all standard baud rates without oscillator tuning. for transmission, reception, error handling, and baudrate detection 5 separate interrupt vectors are provided. in asynchronous mode, 8- or 9-bit data frames (with optional parity bit) are transmitted or received, preceded by a start bit and terminated by one or two stop bits. for multiprocessor communication, a mechanism to distinguish address from data bytes has been included (8-bit data plus wake-up bit mode). irda data transmissions up to 115.2 kbit/s with fixed or programmable irda pulse width are supported. in synchronous mode, bytes (8 bits) are trans mitted or received synchronously to a shift clock which is generated by the asc0/1. the lsb is always shifted first. in both modes, transmission and reception of data is fifo-buffered. an autobaud detection unit allows to detect asynchrono us data frames with its baudrate and mode with automatic initialization of the baudrate generator and the mode control bits. a number of optional hardware error detection capabilities has been included to increase the reliability of data transfers. a parity bit can automatically be generated on transmission or be checked on reception. fram ing error detection allows to recognize data frames with missing stop bits. an overrun error will be generated, if the last character received has not been read out of the receive buffer register at the time the reception of a new character is complete. summary of features full-duplex asynchronous operating modes

serial channels ssc0/ssc1 support full-duplex and half- duplex synchronous communication. it may be configured so it interfaces with serially linked peripheral components, full spi functionality is supported. a dedicated baud rate generator allows to set up all standard baud rates without oscillator tuning. for transmission, recept ion and error handling three separate interrupt vectors are provided. the ssc transmits or receives characters of 2 ? 16 bits length synchronously to a shift clock which can be generated by the ssc (master mode) or by an external master (slave mode). the ssc can start shifting with the lsb or with the msb and allows the selection of shifting and latching clock edges as well as the clock polarity. a number of optional hardware error detection capabilities has been included to increase the reliability of data transfers. transmit error and receive error supervise the correct handling of the data buffer. phase error an d baudrate error detect incorrect

handles the completely autonomous transmission and reception of can frames in accordance with the can specification v2.0 part b (active), i.e. the on-chip twincan module can receiv e and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. two full-can nodes share the twincan module?s resources to optimize the can bus traffic handling and to minimize the cpu load. the module provides up to 32 message objects, which can be assigned to one of the can nodes and can be combined to fifo- structures. each object provides separate masks for acceptance filtering. the flexible combination of full-can functi onality and fifo architecture reduces the efforts to fulfill the real-time requirements of complex embedded control applications. improved can bus monitoring functionality as well as the number of message objects permit precise and comfortable can bus traffic handling. gateway functionality allows automatic data exchange between two separate can bus systems, which reduces cpu load and improves the real time behavior of the entire system. the bit timing for both can nodes is derived from the master clock and is programmable up to a data rate of 1 mbit/s. each can node us es two pins of port 4, port 7, or port 9 to interface to an external bus transceiver. the interface pins are assigned via software. figure 10 twincan

cs lines can be used to increase the total amount of addressable external memory. 3.14 watchdog timer the watchdog timer represents one of the fail-safe mechanisms which have been implemented to prevent the controller from malfunctioning for longer periods of time. the watchdog timer is always enabled after a reset of the chip, and can be disabled until the einit instruction has been execut ed (compatible mode), 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 watchdog timer bef ore it overflows. if, due to hardware or software related failures, the software fails to do so, the watchdog timer overflows and generates an internal hardware reset and pulls the rstout pin low in order to allow external hardware components to be reset. the watchdog timer is a 16-bit timer, clocked with the system clock divided by 2/4/128/ 256. the high byte of the watchdog timer r egister 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 reloaded and the low byte is cleared. thus, time intervals between 13 s and 419 ms can be monitored (@ 40 mhz). the default watchdog timer interval after reset is 3.28 ms (@ 40 mhz). xc164 derivatives functional description data sheet 39 v2.1, 2003-06 3.15 clock generation the clock generation unit uses a programmable on-chip pll with multiple prescalers to generate the clock signals for the xc164 with high flexibility. the master clock f mc is the reference clock signal, and is used for twin can and is output 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 5.1 . the on-chip oscillator can drive an external crystal or accepts an external clock signal. the oscillator clock frequency can be multiplied by the 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 can deliver an independent clock to monitor the clock si gnal generated by the on-chip oscillator. this pll clock is independent from the xtal1 clock. when the expected oscillator 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 oscillate with its basic frequency. the oscillator watchdog can be disabled by switching the pll off. this reduces power consumption, but also no interrupt request will be generated 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 (externally) pulling the rd line low upon a reset, similar to the standard reset configuration. 3.16 parallel ports the xc164 provides up to 79 i/o lines whic h are organized into six input/output ports and one input port. all port lines are bit-addressable, and all input/output lines are individually (bit-wise) programmable 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 inputs. the output drivers of some i/o ports can be configured (pin by pin) for push/pull operation or open-drain operation vi a control registers. during the internal reset, all port pins are configured as inputs (except for pin rstout ). the edge characteristics (shape) and driver characteristics (output current) of the port drivers can be selected via registers poconx. the input threshold of some ports is selectable (ttl or cmos like), where the special cmos like input threshold reduces noise sensitivity 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 functions associated with them. all port lines that are not used for t hese alternate functions may be used as general purpose io lines. xc164 derivatives functional description data

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 xc164 into a special operating mode (control via instructions). idle mode stops the cpu while the peripherals can continue to operate. sleep mode and power down mode stop all clock signals and all operation (rtc may optionally continue running). sleep mode can be terminated by external interrupt signals. clock generation management controls the distribution and the frequency of internal and external clock signals. while the clock signals for currently inactive parts of logic are disabled automatically, the user can reduce the xc164?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). each peripheral can separately be disabled/enabled. the on-chip rtc supports intermittend operation of the xc164 by generating cyclic wake-up signals. this offers full performance to quickly react on action requests while the intermittend sleep phases greatly reduce the average power consumption of the system. xc164 derivatives functional description data sheet 42 v2.1, 2003-06 3.18 instruction set summary table

listed in the following partly represent the characteristics of the xc164 and partly its demands on the system. to aid in interpreting the parameters right, when evaluating them for a design, they are marked in column ?symbol?: cc ( c ontroller c haracteristics): the logic of the xc164 will provide signals with the re spective characteristics. sr ( s ystem r equirement): the external system must provide signals with the respective characteristics to the xc164. 4) overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the specified range: v ov > v ddp + 0.5 v ( i ov >0) or v ov < v ss - 0.5 v ( i ov < 0). the absolute sum of input overload currents on all pins may not exceed 50 ma . the supply voltages must remain within the specified limits. proper operation is not guaranteed if overload conditions occur on functional pins such as xtal1, rd , wr , etc. 5) not 100% tested, guaranteed by design and characterization. 6) an overload current ( i ov ) through a pin injects a certain error current ( i inj ) into the adjacent pins. this error current adds to the respective pin?s leakage current ( i oz ). the amount of error current depends on the overload current and is defined by the overload coupling factor k ov . the polarity of the injected error current is inverse compared to the polarity of the overload current

tested at v aref = v ddp +0.1v, v agnd = 0 v. it is guaranteed by design for all other voltages within the defined voltage range. if the analog reference supply voltage drops below 4.5 v (i.e. v aref 4.0 v) or exceeds the power supply voltage by up to 0.2 v (i.e. v aref = v ddp + 0.2 v) the maximum tue is increased to 3 lsb. this range is not 100% tested. the specified tue is guaranteed only, if the absolute sum of input overload currents on port 5 pins (see i ov specification) does not exceed 10 ma, and if v aref and v agnd remain stable during the respective period of time. during the reset calibration sequence the maximum tue may be 4 lsb. 2) v ain may exceed v agnd or v aref up to the absolute maximum ratings. however, the conversion result in these cases will be x000 h or x3ff h ,

of the xc164 is controlled by the internal master clock f mc . the master clock signal f mc can be generated from the 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 the used mechanism to generate f mc . this influence must be regarded when calculating the timings for the xc164. figure 15 generation mechanisms for the master clock note: the example for pll operation shown in figure 15 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 generate the master clock is selected by register pllcon. cpu and ebc are clocked with 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 cpsys in register syscon1. the specification of the external timing (ac characteristics) depends on the period of the cpu clock, called ?tcp?. the other peripherals are suppli ed with the system clock signal f sys which has the same frequency as the cpu clock signal f cpu . tcm tcm f mc f osc f mc f osc phase locked loop operation (1:n) direct clock drive (1:1) tcm f mc f osc prescaler operation (n:1) xc164 derivatives timing parameters data sheet 57 v2.1, 2003-06 bypass operation when bypass operation is configured (pllctrl = 0x b ) the master clock is derived from the internal oscillator (input clock si gnal xtal1) through 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 achieved by selecting the maximum values for both divider factors: f mc = f osc / ((3+1) (14+1)) = f osc / 60. phase locked loop (pll) when pll operation is configured (pllctrl = 11 b ) the on-chip phase locked loop is enabled and provides the master clock. the pll multiplies the input frequency by the factor f ( f mc = f osc f ) which results from the input divider, the multiplication factor, and the output divider ( f = pllmul+1 / (pllidiv+1 pllodiv+1)). the pll circuit synchronizes the master clock to the input cl ock. this synchronization is done smoothly, i.e. the master clock frequency does not change abruptly. due to this adaptation to the input clock the frequency of f mc is constantly adjusted so it is locked to f osc . the slight variation causes a jitter of f mc which also affects the duration of individual tcms. the timing listed in the ac characteristics refers to tcps. because f cpu is derived from f mc , the timing must be calculated using the 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 relative deviation for periods of more than one tcp is lower than for one single tcp (see formula and figure 16 ). this is especially important for bus cycles us ing waitstates and e.g. for the operation of timers, serial interfaces, etc. for all slower operations and longer periods (e.g. pulse train generation or measurement, lower baudrates, etc.) the deviation caused by the pll jitter is negligible. the value of the accumulated pll jitter depends on the number of consecutive vco output cycles within the respective timefram e. the vco output clock is divided by the output prescaler (k = pllodiv+1) to generate the 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). xc164 derivatives timing parameters data sheet 58 v2.1, 2003-06 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 can be approximated by: d n max [ns] = (1.5 + 600 / (k f mc )). figure 16 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 bands can be selected for the vco, so the operation of the pll can be adjusted to a wide range of input and output frequencies: table 15 vco bands for pll operation 1) 1) values guarnteed by design characterisation. pllcon.pllvb vco frequency range base frequency range 00 100 150 mhz 20 80 mhz 01 150 200 mhz 40 130 mhz 10 200 250 mhz 60 180 mhz 11 reserved mcb04413_xc.vsd acc. jitter d n 8 6 ns 4 2 1 0 510 20 25 n 1 0 m h z k=5 2 0 m h z 4 0 m h z 7 5 3 15 k=6 k=12 k=15 k=8 k=10 1 xc164 derivatives timing parameters data sheet 59 v2.1, 2003-06 5.2 external clock drive xtal1 figure 17 external clock drive xtal1 note: if the on-chip oscillator is used together with a crystal or a ceramic resonator, the oscillator frequency is limited to a range of 4 mhz to 16 mhz. it is strongly recommended to measur e the oscillation allowance (negative resistance) in the final target syst em (layout) to determine the optimum parameters for the oscillator operation. please refer to the limits specified by the crystal supplier. when driven by an external clock signal it will accept the specified frequency range. operation at lower input frequencies is possible but is guaranteed by design only (not 100% tested). table 16 external clock drive characteristics (operating conditions apply) parameter symbol limit values unit min. max. oscillator period t osc sr 20 250 1) 1) the maximum limit is only relevant for pll operation to ensure the minimum input frequency for the pll. ns high time 2) 2) the clock input signal must reach the defined levels v ilc and v ihc . t 1 sr 6 ?
