11aug98@14:48h intermediate version semiconductor group 8 1998-08 c163-l functional description the architecture of the c163-l combines advantages of both risc and cisc processors and of advanced peripheral subsystems in a very well-balanced way. the following block diagram gives an overview of the different on-chip components and of the advanced, high bandwidth internal bus structure of the c163-l. note : all time specifications refer to a cpu clock of 25/12 mhz for 5/3 v operation (see definition in the ac characteristics section). figure 3 block diagram pll
11aug98@14:48h intermediate version semiconductor group 9 1998-08 c163-l memory organization the memory space of the c163-l is configured in a von neumann architecture which means that code memory, data memory, registers and i/o ports are organized within the same linear address space which includes 16 mbytes. the entire memory space can be accessed bytewise or wordwise. particular portions of the on-chip memory have additionally been made directly bit addressable. the c163-l is prepared to incorporate on-chip mask-programmable rom, otp or flash memory for code or constant data. currently no program memory is integrated. 1 kbyte of on-chip ram is provided as a storage for user defined variables, for the system stack, general purpose register banks and even for code. a register bank can consist of up to 16 wordwide (r0 to r15) and/or bytewide (rl0, rh0, , rl7, rh7) so-called general purpose registers (gprs). 1024 bytes (2 * 512 bytes) of the address space are reserved 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 other/future members of the c166 family. in order to meet the needs of designs where more memory is required than is provided on chip, up to 16 mbytes of external ram and/or rom can be connected to the microcontroller.
11aug98@14:48h intermediate version semiconductor group 10 1998-08 c163-l external bus controller all of the external memory accesses are performed 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, which are as follows: C 16-/18-/20-/24-bit addresses, 16-bit data, demultiplexed C 16-/18-/20-/24-bit addresses, 16-bit data, multiplexed C 16-/18-/20-/24-bit addresses, 8-bit data, multiplexed C 16-/18-/20-/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. important timing characteristics of the external bus interface (memory cycle time, memory tri- state time, length of ale and read write delay) have been made programmable 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 register pairs addrselx / busconx) which allow to access different resources with different bus characteristics. these address windows are arranged hierarchically where buscon4 overrides buscon3 and buscon2 overrides buscon1. all accesses to locations not covered by these 4 address windows are controlled by buscon0. up to 5 external cs signals (4 windows plus default) can be generated in order to save external glue logic. access to very slow memories is supported via a particular ready function. a hold /hlda protocol is available for bus arbitration and allows to share external resources with other bus masters. the bus arbitration is enabled by setting bit hlden in register syscon. after setting hlden once, pins p6.7...p6.5 (breq , hlda , hold ) are automatically controlled by the ebc. in master mode (default after reset) the hlda pin is an output. by setting bit dp6.7 to 1 the slave mode is selected where pin hlda is switched to input. this allows to directly connect the slave controller to another master controller without glue logic. for applications which require less than 16 mbytes of external memory space, this address space can be restricted to 1 mbyte, 256 kbyte or to 64 kbyte. in this case port 4 outputs four, two or no address lines at all. it outputs all 8 address lines, if an address space of 16 mbytes is used. note: when the on-chip ssp module is to be used the segment address output on port 4 must be limited to 4 bits (ie. a19...a16) in order to enable the alternate function of the ssp interface pins.
11aug98@14:48h intermediate version semiconductor group 11 1998-08 c163-l central processing unit (cpu) the main core of the cpu consists of a 4-stage instruction pipeline, a 16-bit arithmetic and logic unit (alu) and dedicated sfrs. additional hardware has been spent for a separate multiply and divide unit, a bit-mask generator and a barrel shifter. based on these hardware provisions, most of the c163-ls instructions can be executed in just one machine cycle which requires 80 ns at 25-mhz cpu clock. for example, shift and rotate instructions are always processed during one machine cycle independent of the number of bits to be shifted. all multiple-cycle instructions have been optimized so that they can be executed very fast as well: branches in 2 cycles, a 16 16 bit multiplication in 5 cycles and a 32-/16 bit division in 10 cycles. another pipeline optimization, the so-called jump cache, allows reducing the execution time of repeatedly performed jumps in a loop from 2 cycles to 1 cycle. figure 4 cpu block diagram
11aug98@14:48h intermediate version semiconductor group 12 1998-08 c163-l the cpu disposes of an actual register context consisting of up to 16 wordwide gprs which are physically allocated within the on-chip ram area. a context pointer (cp) register determines the base address of the active register bank to be accessed by the cpu at a time. the number of register banks is only restricted by the available internal ram space. for easy parameter passing, a register bank may overlap others. a system stack of up to 512 words is provided as a storage for temporary data. the system stack is allocated 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 efficient c163-l instruction set which includes the following instruction classes: C arithmetic instructions C logical instructions C boolean bit manipulation instructions C compare and loop control instructions C shift and rotate instructions C prioritize instruction C data movement instructions C system stack instructions C jump and call instructions C return instructions C system control instructions C 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.
11aug98@14:48h intermediate version semiconductor group 13 1998-08 c163-l interrupt system with an interrupt response time within a range from just 200 ns to 480 ns (in case of internal program execution), the c163-l is capable of reacting very fast to the occurence of non- deterministic events. the architecture of the c163-l 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 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 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. an individual pec transfer counter is implicity 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 reception of blocks of data. the c163- l 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 sources. via its related register, each source 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 the standard interrupt processing, each of the possible interrupt sources 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.

11aug98@14:48h intermediate version semiconductor group 15 1998-08 c163-l the c163-l also provides an excellent mechanism to identify and to process exceptions or error conditions that arise during run-time, so-called hardware traps. hardware traps cause immediate non-maskable system reaction which is similar to a standard interrupt service (branching to a dedicated vector table location). the occurence of a hardware trap is additionally signified by an individual bit in the trap flag register (tfr). except when another higher prioritized trap service is in progress, a hardware trap will interrupt any actual program execution. in turn, hardware trap services can normally not be interrupted by standard or pec interrupts. the following table shows all of the possible exceptions or error conditions that can arise during run- time: exception condition trap flag trap vector vector location trap number trap priority reset functions: hardware reset software reset watchdog timer overflow reset reset reset 000000 h 000000 h 000000 h 00 h 00 h 00 h iii iii iii class a hardware traps: non-maskable interrupt stack overflow stack underflow nmi stkof stkuf nmitrap stotrap stutrap 000008 h 000010 h 000018 h 02 h 04 h 06 h ii ii ii class b hardware traps: undefined opcode protected instruction fault illegal word operand access illegal instruction access illegal external bus access undopc prtflt illopa illina illbus btrap btrap btrap btrap btrap 000028 h 000028 h 000028 h 000028 h 000028 h 0a h 0a h 0a h 0a h 0a h i i i i i reserved [2c h C 3c h ][0b h C 0f h ] software traps trap instruction any [000000 h C 0001fc h ] in steps of 4 h any [00 h C 7f h ] current cpu priority
11aug98@14:48h intermediate version semiconductor group 16 1998-08 c163-l general purpose timer (gpt) unit the gpt unit represents a very flexible multifunctional timer/counter structure which may be used for many different time related tasks such as event timing and counting, pulse width and duty cycle measurements, pulse generation, or pulse multiplication. the gpt 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 concatenated 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 three basic modes of operation, which are timer, gated timer, and counter mode. in timer mode, the input clock for a timer is derived from the cpu 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 supported in gated timer mode, where the operation of a timer is controlled by the gate 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 320 ns (@ 25 mhz cpu clock). 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. figure 5 block diagram of gpt1 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 port a pin (t3out) e.g. for time out monitoring of external hardware components, or may be used internally to clock timers t2 and t4 for measuring long time periods with high resolution.
11aug98@14:48h intermediate version semiconductor group 17 1998-08 c163-l 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. figure 6 block diagram of gpt2 with its maximum resolution of 160 ns (@ 25 mhz), the gpt2 module provides precise event control and time measurement. 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 programmable 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). timer t6 has an output toggle latch (t6otl) which changes its state on each timer overflow/underflow. concatenation of the timers is supported via t6otl. the state of this latch may be used to clock timer t5, or it may be output on a port pin (t6out). the overflows/underflows of timer t6 can additionally be used 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 after the capture procedure. this allows absolute time differences to be measured or pulse multiplication to be performed without software overhead.
11aug98@14:48h intermediate version semiconductor group 18 1998-08 c163-l parallel ports the c163-l provides up to 77 i/o lines which 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 three 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. all port lines have programmable alternate input or output functions associated with them. port0 and port1 may be used as address and data lines when accessing external memory, while port 4 outputs the additional segment address bits a23/19/17...a16 in systems where segmentation is enabled to access more than 64 kbytes of memory. port 6 provides optional bus arbitration signals (breq , hlda , hold ) and chip select signals. port 3 includes alternate functions of timers, serial interfaces, the optional bus control signal bhe and the system clock output (clkout). port 5 is used for timer control signals. all port lines that are not used for these alternate functions may be used as general purpose i/o lines. serial channels serial communication with other microcontrollers, processors, terminals or external peripheral components is provided by two serial interfaces with different functionality, an asynchronous/ synchronous serial channel (asc0) and a synchronous serial port (ssp). the asc0 is upward compatible with the serial ports of the siemens 8-bit microcontroller families and supports full-duplex asynchronous communication at up to 781 kbaud and half-duplex synchronous communication at up to 3.125 mbaud @ 25 mhz cpu clock. a dedicated baud rate generator allows to set up all standard baud rates without oscillator tuning. for transmission, reception and error handling 4 separate interrupt vectors are provided. in asynchronous mode, 8- or 9-bit data frames 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). in synchronous mode, the asc0 transmits or receives bytes (8 bits) synchronously to a shift clock which is generated by the asc0. the asc0 always shifts the lsb first. a loop back option is available for testing purposes. 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. framing 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. the ssp transmits 1...3 bytes or receives 1 byte after sending 1...3 bytes synchronously to a shift clock which is generated by the ssp. the ssp can start shifting with the lsb or with the msb and allows to select shifting and latching clock edges as well as the clock polarity. up to two chip select lines may be activated in order to direct data transfers to one or both of two peripheral devices. one general interrupt vector is provided for the ssp.
11aug98@14:48h intermediate version semiconductor group 19 1998-08 c163-l 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 only be disabled in the time interval until the einit (end of initialization) instruction has been executed. thus, the chips start-up procedure is always monitored. the software has to be designed to service the watchdog timer before 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 either by 2 or by 128. the high byte of the watchdog timer 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 reloaded. thus, time intervals between 20 m s and 336 ms can be monitored (@ 25 mhz). the default watchdog timer interval after reset is 5.24 ms (@ 25 mhz). oscillator watchdog during direct drive or prescaler operation the oscillator watchdog (owd) monitors the clock signal generated by the on-chip oscillator (either with a crystal or via external clock drive). for this operation the pll provides a clock signal which is used to supervise transitions on the oscillator clock. this pll clock is independent from the xtal1 clock. when the expected oscillator clock transitions are missing the owd activates the pll unlock / owd interrupt node and supplies the cpu with the pll clock signal. under these circumstances the pll will oscillate with its basic frequency. a low level on pin owe disables the pll and the owds interrupt output so the clock signal is derived from the oscillator clock in any case. note: the cpu clock source is only switched back to the oscillator clock after a hardware reset. for 3 v operation pin owe must always be low (owd disabled) as the pll cannot deliver an appropriate clock signal in this case. for 5 v operation pin owe should only be pulled low (pll disabled) if direct drive or prescaler operation is configured. all other configurations (pll factors) result in direct drive operation.

11aug98@14:48h intermediate version semiconductor group 34 1998-08 c163-l ac characteristics definition of internal timing the internal operation of the c163-l is controlled by the internal cpu clock f cpu . both edges of the cpu clock can trigger internal (eg. pipeline) or external (eg. bus cycles) operations. the specification of the external timing (ac characteristics) therefore depends on the time between two consecutive edges of the cpu clock, called tcl (see figure below). figure 10 generation mechanisms for the cpu clock the cpu clock signal can be generated via different mechanisms. the duration of tcls and their variation (and also the derived external timing) depends on the used mechanism to generate f cpu . this influence must be regarded when calculating the timings for the c163-l. note: the example for pll operation shown in the figure above refers to a pll factor of 4. the used mechanism to generate the cpu clock is selected during reset via the logic levels on pins p0.15-13 (p0h.7-5). the table below associates the combinations of these three bits with the respective clock generation mode. tcl tcl tcl tcl f cpu f osc f cpu f osc phase locked loop operation direct clock drive tcl tcl f cpu f osc prescaler operation
11aug98@14:48h intermediate version semiconductor group 35 1998-08 c163-l prescaler operation when pins p0.15-13 (p0h.7-5) equal 001 during reset the cpu clock is derived from the internal oscillator (input clock signal) by a 2:1 prescaler. the frequency of f cpu is half the frequency of f osc and the high and low time of f cpu (ie. the duration of an individual tcl) is defined by the period of the input clock f osc . the timings listed in the ac characteristics that refer to tcls therefore can be calculated using the period of f osc for any tcl. direct drive when pins p0.15-13 (p0h.7-5) equal 011 during reset the on-chip phase locked loop is disabled and the cpu clock is directly driven from the internal oscillator with the input clock signal. the frequency of f cpu directly follows the frequency of f osc so the high and low time of f cpu (ie. the duration of an individual tcl) is defined by the duty cycle of the input clock f osc . the timings listed below that refer to tcls therefore must be calculated using the minimum tcl that is possible under the respective circumstances. this minimum value can be calculated via the following formula: tcl min = 1/f osc * dc min (dc = duty cycle) for two consecutive tcls the deviation caused by the duty cycle of f osc is compensated so the duration of 2tcl is always 1/f osc . the minimum value tcl min therefore has to be used only once for timings that require an odd number of tcls (1,3,...). timings that require an even number of tcls (2,4,...) may use the formula 2tcl = 1/f osc . note: the address float timings in multiplexed bus mode (t 11 and t 45 ) use the maximum duration of tcl (tcl max = 1/f osc * dc max ) instead of tcl min . 1) the external clock input range refers to a cpu clock range of 10...25 mhz. 2) the maximum frequency depends on the duty cycle of the external clock signal. direct drive is also selected instead of pll operation if pin owe = 0 in such a case. c163-l clock generation modes p0.15-13 (p0h.7-5) cpu frequency f cpu = f osc * f external clock input range 1) notes 111 f osc * 4 2.5 to 6.25 mhz default configuration 110 f osc * 3 3.33 to 8.33 mhz 101 f osc * 2 5 to 12.5 mhz 100 f osc * 5 2 to 5 mhz 011 f osc * 1 1 to 25 mhz direct drive 2) 010 f osc * 1.5 6.66 to 16.6 mhz 001 f osc / 2 2 to 50 mhz cpu clock via prescaler 000 f osc * 2.5 4 to 10 mhz
11aug98@14:48h intermediate version semiconductor group 36 1998-08 c163-l phase locked loop for all other combinations of pins p0.15-13 (p0h.7-5) during reset the on-chip phase locked loop is enabled and provides the cpu clock (see table above). the pll multiplies the input frequency by the factor f which is selected via the combination of pins p0.15-13 (i.e. f cpu = f osc * f ). with every f th transition of f osc the pll circuit synchronizes the cpu clock to the input clock. this synchronization is done smoothely, i.e. the cpu clock frequency does not change abruptly. due to this adaptation to the input clock the frequency of f cpu is constantly adjusted so it is locked to f osc . the slight variation causes a jitter of f cpu which also effects the duration of individual tcls. the timings listed in the ac characteristics that refer to tcls therefore must be calculated using the minimum tcl that is possible under the respective circumstances. the actual minimum value for tcl 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 tcl is lower than for one single tcl (see formula and figure below). for a period of n * tcl the minimum value is computed using the corresponding deviation d n : ( n * tcl) min = n * tcl nom - d n d n [ns] = (13.3 + n *6.3) / f cpu [mhz], where n = number of consecutive tcls and 1 n 40. so for a period of 3 tcls @ 25 mhz (i.e. n = 3): d 3 = (13.3 + 3 * 6.3) / 25 = 1.288 ns, and (3tcl) min = 3tcl nom - 1.288 ns = 58.7 ns (@ f cpu = 25 mhz). this is especially important for bus cycles using 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 neglectible. note: for all periods longer than 40 tcl the n=40 value can be used (see figure below). figure 11 approximated maximum accumulated pll jitter note: the pll only operates within the standard supply voltage range of v dd = 4.5 - 5.5 v. 40 20 10 5 1 1 10 20 n this approximated formula is valid for 1 n 40 and 10mhz f cpu 25mhz. 26.5 max.jitter d n [ns] 20 mhz 25 mhz 16 mhz 10 mhz
