xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 55 v2.1, 2011-07 this common memory space consists of 16 mbytes organized as 256 segments of 64 kbytes; each segment contains four data pages of 16 kbytes. the entire memory space can be accessed bytewise or wordwise. portions of the on-chip dpram and the register spaces (esfr/sfr) additionally are directly bit addressable. 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 access to the program memories su ch as flash memory and psram. the data management unit (dmu) handles al l data transfers and, therefore, controls access to the dsram and the on-chip peripherals. both units (pmu and dmu) are connected to the high-speed system bus so that they can 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. these in clude peripherals on the lxbus such as usic or multican. the system bus allows concurrent two-wa y communication for maximum transfer performance. up to 32 kbytes of on-chip program sram (psram) are provided to store user code or data. the psram is accessed via the pm u and is optimized for code fetches. a section of the psram with programmab le size can be write-protected. up to 16 kbytes of on-chip data sram (dsram) are used for storage of general user data. the dsram is accessed via a separate in terface and is optimized for data access. 2 kbytes of on-chip dual-port ram (dpram) provide storage for user-defined variables, for the system stack, and for gener al purpose register banks. a register bank can consist of up to 16 word-wide (r0 to r15) and/or byte-wide (rl0, rh0, ?, rl7, rh7) general purpose registers (gprs). the upper 256 bytes of the dpram are direct ly bit addressable. when used by a gpr, any location in the dpram is bit addressable. data sram 00?a000 h 00?dfff h 16 kbytes ? reserved for dsram 00?8000 h 00?9fff h 8 kbytes ? external memory area 00?0000 h 00?7fff h 32 kbytes ? 1) accesses to the shaded areas are reserved. in devices with external bus interface these accesses generate external bus accesses. 2) the areas marked with ? xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 56 v2.1, 2011-07 8 kbytes of on-chip stand-by sram (sbram) provide storage for system-relevant user data that must be preserved while the major part of the device is powered down. the sbram is accessed via a specific interface and is powered in domain m. 1024 bytes (2 512 bytes) of the address space are reserved for the special function register areas (sfr space and esfr space) . sfrs are word-wide registers which are used to control and monitor functions of the different on-chip units. unused sfr addresses are reserved for future members of the xc2000 family. in order to ensure upward compatibility they should either not be accessed or written with zeros. the on-chip flash memory stores code, constant data, and control data. the on-chip flash memory consists of 1 module of 64 kbytes (preferably for data storage) and modules with a maximum capacity of 256 kb ytes each. each module is organized in sectors of 4 kbytes. the uppermost 4-kbyte sector of segment 0 (located in flash module 0) is used internally to store operation contro l parameters and protection information. note: the actual size of the flash memory depends on the chosen device type. each sector can be separately write protected 1) , erased and programmed (in blocks of 128 bytes). the complete flash area can be read-protected. a user-defined password sequence temporarily unlocks protected areas. the flas h modules combine 128-bit read access with protected and efficient writing algorithms for programming and erasing. dynamic error correction provides extremely high read data security for all read access operations. access to different flash modules can be executed in parallel. for flash parameters, please see section 4.5 . memory content protection the contents of on-chip memories can be pr otected against soft errors (induced e.g. by radiation) by activating the parity mec hanism or the error correction code (ecc). the parity mechanism can detect a single-bit error and prevent the software from using incorrect data or executing incorrect instructions. the ecc mechanism can detect and automatically correct single-bit errors. this supports the stable operation of the system. it is strongly recommended to activate the ecc mechanism wherever possible because this dramatically increases the robustness of an application against such soft errors. 1) to save control bits, sectors are clustered for protection purposes, they remain separate for programming/erasing.
xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 57 v2.1, 2011-07 3.2 external bus controller all external memory access operations are performed by a special on-chip external bus controller (ebc). the ebc also controls access to resources co nnected to the on-chip lxbus (multican and the usic modules). the lxbus is an internal representation of the external bus that allows access to in tegrated peripherals and modules in the same way as to external components. the ebc can be programmed either to single chip mode, when no external memory is required, or to an external bus mode with the following selections 1) : ? address bus width with a range of 0 ? 24-bit ? data bus width 8-bit or 16-bit ? bus operation multiplexed or demultiplexed the bus interface uses port 10 and port 2 for addresses and data. in the demultiplexed bus modes, the lower addresses are output separately on port 0 and port 1. the number of active segment address lines is selectable , restricting the external address space to 8 mbytes ? 64 kbytes. this is required when in terface lines shall be assigned to port 2. external cs signals (address windows plus default) can be generated and output on port 4 in order to save external glue logic. external modules can be directly connected to the common address/data bus and their individual select lines. a hold /hlda protocol is available for bus arbitratio n; this allows the sharing of external resources with other bus masters. the bus arbi tration is enabled by software, after which pins p3.0 ? p3.2 (breq , hlda , hold ) are automatically controlled by the ebc. in master mode (default after reset) the hlda pin is an output. in slave mode pin hlda is switched to be an input. this allows the direct connection of the slave controller to another master controller without glue logic. important timing characteristics of the ex ternal bus interface are programmable (with registers tconcsx/fconcsx) to allow the user to adapt it to a wide range of different types of memories and external peripherals. access to very slow memories or modules with varying access times is supported by a special ?ready? function. the active level of the control input signal is selectable. in addition, up to four independent address windows may be defined (using registers addrselx) to control access to 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 four address windows are controlled by tconcs 0/fconcs0. the currently active window can generate a chip select signal. the external bus timing is based on t he rising edge of the reference clock output clkout. the external bus protocol is compat ible with that of the standard c166 family. 1) bus modes are switched dynamically if several addr ess windows with different mode settings are used.

xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 59 v2.1, 2011-07 with this hardware most xc 228xm instructions are executed in a single machine cycle of 12.5 ns with an 80-mhz cpu clock. for example, shift and rotate instructions are always processed during one machine cycle, no ma tter how many bits are shifted. also, multiplication and most ma c instructions execute in one cycle. all multiple-cycle instructions have been optimized so that t hey can be executed very fast; for example, a 32-/16-bit division is started within 4 cycle s while the remaining cycles are executed in the background. another pipeline optimization, the branch target prediction, eliminates the execution time of branch instru ctions if the prediction was correct. the cpu has a register context consisting of up to three register banks with 16 word- wide gprs each at its disposal. one of these register banks is physi cally allocated within the on-chip dpram area. a context pointer (cp) register determines the base address of the active register bank accessed by the cpu at any time. the number of these register bank copies 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 32 kwords is provid ed for storage of temporary data. the system stack can be allocated to any location within the address space (preferably in the on-chip ram area); it is accessed by the cpu with th e stack pointer (sp) register. two separate sfrs, stkov and stkun, are implicitly compared with t he stack pointer value during each stack access to detect stack overflow or underflow. the high performance of the cpu hardware im plementation can be be st utilized by the programmer with the highly efficient xc228xm instruction set. this 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 contro l 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.
xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 60 v2.1, 2011-07 3.4 memory protection unit (mpu) the xc228xm?s memory protection unit (mpu ) protects user-specified memory areas from unauthorized read, write, or instruct ion fetch accesses. the mpu can protect the whole address space including the peripheral area. this completes establisched mechanisms such as the register securi ty mechanism or stack overrun/underrun detection. four protection levels support flexible system programming wh ere operating system, low level drivers, and applications run on se parate levels. each protection level permits different access restri ctions for instructions and/or data. every access is checked (if the mpu is enabled) and an access violating the permission rules will be marked as invalid and leads to a protection trap. a set of protection registers for each protec tion level specifies the address ranges and the access permissions. applications requ iring more than 4 protection levels can dynamically re-program the protection registers. 3.5 memory checker module (mchk) the xc228xm?s memory checker module calc ulates a checksum (f ractional polynomial division) on a block of data, often called cyclic redundancy code (crc). it is based on a 32-bit linear feedback shift register and may, therefore, also be used to generate pseudo-random numbers. the memory checker module is a 16-bit parallel input signature compression circuitry which enables error detection within a block of data stored in me mory, registers, or communicated e.g. via serial communication lines. it reduces the probability of error masking due to repeated error patterns by ca lculating the signature of blocks of data. the polynomial used for operation is configurable, so most of the commonly used polynomials may be used. also, the block size for generating a crc result is configurable via a local counter. an interrupt may be generated if testing the current data block reveals an error. an autonomous crc compare circuitry is included to enable redundant error detection, e.g. to enable higher safety integrity levels. the memory checker module provides enhan ced fault detection (beyond parity or ecc) for data and instructions in volatile and non volatile memories. this is especially important for the safety and reliability of embedded systems.
xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 61 v2.1, 2011-07 3.6 interrupt system the architecture of the xc228xm supports several mechanisms for fast and flexible response to service requests; these can be generated from various sources internal or external to the microcontroller. any of thes e interrupt requests can be programmed to be serviced by the interrupt controller or by the peripheral event controller (pec). where in a standard interrupt service the current program execution is suspended and a branch to the interrupt vect or table is performed, just one cycle is ?stolen? from the current cpu activity to perform a pec servic e. a pec service implies a single byte or word data transfer between any two memo ry locations with an additional increment of either the pec source pointer, the destinat ion 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-relate d vector location. pec services are particularly well suited to s upporting the transmission or reception of blocks of data. the xc228xm has eight pec channels, each whith fast interrupt-driven data transfer capabilities. with a minimum interrupt response time of 7/11 1) cpu clocks, the xc228xm can react quickly to the occurrence of non-deterministic events. interrupt nodes and source selection the interrupt system provides 96 physica l nodes with separate control register containing an interrupt request flag, an interrupt enable flag and an interrupt priority bit field. most interrupt sources are assigned to a dedicated node. a particular subset of interrupt sources shares a set of nodes. the source selection can be programmed using the interrupt source selection (issr) registers. external request unit (eru) a dedicated external request unit (eru) is provided to route and preprocess selected on-chip peripheral and external interrupt requests. the eru features 4 programmable input channels with event trigger logic (etl ) a routing matrix and 4 output gating units (ogu). the etl features rising edge, falli ng edge, or both edges event detection. the ogu combines the detected interrupt ev ents and provides filtering capabilities depending on a programmable pattern match or miss. trap processing the xc228xm provides efficient mechanisms to identify and process exceptions or error conditions that arise during run-time, the so-called ?hardware traps?. a hardware trap causes an immediate system reaction simila r to a standard interrupt service (branching 1) depending if the jump cache is used or not.
xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 62 v2.1, 2011-07 to a dedicated vector table location). the occurrence of a hardware trap is also indicated by a single bit in the trap flag register (tfr ). unless another higher-priority trap service is in progress, a hardware trap will interrupt any ongoing program execution. in turn, hardware trap services can normally not be interrupted by standard or pec interrupts. depending on the package option up to 3 external service request (esr) pins are provided. the esr unit processes their i nput values and allows to implement user controlled trap functions (system requests sr0 and sr1). in this way reset, wakeup and power control can be efficiently realized. software interrupts are supported by the ?trap? instruction in combination with an individual trap (interrupt) number. alternatively to emulate an interrupt by software a program can trigger interrupt requests by wr iting the interrupt request (ir) bit of an interrupt control register. 3.7 on-chip debug support (ocds) the on-chip debug support system built into the xc228xm provides a broad range of debug and emulation features. user softwa re running on the xc228xm can be debugged within the target system environment. the ocds is controlled by an external debugging device via the debug interface. this either consists of the 2-pin device access po rt (dap) or of the jt ag port conforming to ieee-1149. the debug interface can be completed with an optional break interface. the debugger controls the ocds with a set of dedicated registers accessible via the debug interface (dap or jtag). in addition the ocds system can be controlled by the cpu, e.g. by a monitor program. an inject ion 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 su pported, as is the in jection 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 mo nitor call, a data transfer, or/and the activation of an external signal. tracing data can be obtained via the debug inte rface, or via the external bus interface for increased performance. tracing of program executio n is supported by the xc2000 family emulation device. the dap interface uses two interface signals, the jtag interface uses four interface signals, to communicate with external circ uitry. the debug interface can be amended with two optional break lines.
xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 63 v2.1, 2011-07 3.8 capture/compare unit (capcom2) the capcom2 unit supports generation and control of timing sequences on up to 16 channels with a maximum resolution of one system clock cycle (eight cycles in staggered mode). the capcom2 unit is typically used to handle high-speed i/o tasks such as pulse and waveform generation, pulse width modulation (pwm), digital to analog (d/a) conversion, software timing, or time recording with respect to external events. two 16-bit timers (t7/t8) with reload regi sters provide two independent time bases for the 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 or variation for the timer period and resolution and allows precise adjustments to the application-specif ic requirements. in addition, an external count input allows event scheduling for the capt ure/compare registers relative to external events. the capture/compare register array cont ains 16 dual purpose capture/compare registers, each of which may be individual ly allocated to either capcom timer and programmed for capture or compare function. all registers have each one port pin associated with it which serves as an input pin for triggering the capture function, or as an output pin to indicate the occurrence of a compare event. when a capture/compare register has been selected for capture mode, the current contents of the allocated timer will be latched (?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 c ontents of the allocated timers. when a match occurs between the timer value and the value in a capture/compare register, specific actions will be tak en based on the selected compare mode. table 9 compare modes compare modes function mode 0 interrupt-only compare mode; several compare interrupts per timer period are possible mode 1 pin toggles on each compare match; several compare events per timer period are possible

xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 70 v2.1, 2011-07 with its maximum resolution of 2 system clock cycles, 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 programma ble prescaler or with external signals. the counting direction (up/down) for each timer can be programmed by software or altered dynamically with an external signal on a por t pin (txeud). concatenation of the timers is supported with the output toggle latch (t6o tl) 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 also be used to clock the capcom2 timers and to initiate a reload from the caprel register. the caprel register can capt ure the contents of timer t5 based on an external signal transition on the corresponding port pin (capin); timer t5 may optionally be cleared after the capture procedure. this allo ws the xc228xm to measure absolute time differences or to perform pulse multiplication without software overhead. the capture trigger (timer t5 to caprel ) can also be generated upon transitions of gpt1 timer t3 inputs t3in and/or t3eud. this is especially advantageous when t3 operates in incremental interface mode.

xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 74 v2.1, 2011-07 3.12 a/d converters for analog signal measurement, up to two 10-bit a/d converters (adc0, adc1) with 16 + 8 multiplexed input channels and a sample and hold circuit have been integrated on-chip. 4 inputs can be converted by both a/d converters. conversions use the successive approximation method. the sample time (to charge the capacitors) and the conversion time are programmable so that t hey can be adjusted to the external circuit. the a/d converters can also operate in 8-bi t conversion mode, further reducing the conversion time. several independent conversion result regist ers, selectable inte rrupt requests, and highly flexible conversion sequences prov ide a high degree of programmability to meet the application requirements. both modules can be synchronized to allow parallel sampling of two input channels. for applications that require more analog input channels, external analog multiplexers can be controlled automatically. for app lications that require fewer analog input channels, the remaining channel inputs can be used as digital input port pins. the a/d converters of the xc228xm support tw o types of request sources which can be triggered by several internal and external events. ? parallel requests are activated at the sa me time and then executed in a predefined sequence. ? queued requests are executed in a user-defined sequence. in addition, the conversion of a specific channel can be inserted into a running sequence without disturbing that sequence. all requests are arbitrated according to the priority level assigned to them. data reduction features reduce the number of required cpu access operations allowing the precise evaluation of analog inputs (hig h conversion rate) even at a low cpu speed. result data can be reduced by limit checking or accumulation of results. the peripheral event controller (pec) can be used to control the a/d converters or to automatically store conversion results to a table in memory for later evaluation, without requiring the overhead of enter ing and exiting interrupt routines for each data transfer. each a/d converter contains eight result regi sters which can be concatenated to build a result fifo. wait-f or-read mode can be ena bled for each result r egister to prevent the loss of conversion data. in order to decouple analog inputs from digi tal noise and to avoid input trigger noise, those pins used for analog input can be disc onnected from the digital input stages. this can be selected for each pin separately with the port x digital input disable registers. the auto-power-down feature of the a/d co nverters minimizes the power consumption when no conversion is in progress. broken wire detection for each channel and a multiplexer test mode provide information to verify the proper operat ion of the analog signal sources (e.g. a sensor system).

xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 77 v2.1, 2011-07 3.14 multican module the multican module contains independently operating can nodes with full-can functionality which are able to exchange da ta and remote frames using a gateway function. transmission and reception of can frames is handled in accordance with can specification v2.0 b (active). each can nod e can receive and transmit standard frames with 11-bit identifiers as well as ex tended frames with 29-bit identifiers. all can nodes share a common set of mess age objects. each message object can be individually allocated to one of the can nodes. besides serving as a storage container for incoming and outgoing frames, message objects can be combined to build gateways between the can nodes or to set up a fifo buffer. note: the number of can nodes and messa ge objects depends on the selected device type. the message objects are organized in doubl e-chained linked lists, where each can node has its own list of message objects. a can node stores frames only into message objects that are allocated to its own message object list and it transmits only messages belonging to this message object list. a powerful, command-driven list controller performs all message object list operations. figure 12 block diagram of multican module mc_ multican_ block.vsd multican module kernel interrupt control f can port control can control message object buffer can node 0 linked list control clock control address decoder can node n txdcn rxdcn txdc0 rxdc0 ... ... ...

xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 79 v2.1, 2011-07 3.16 watchdog timer the watchdog timer is one of the fail-sa fe mechanisms which have been implemented to prevent the controller from malfun ctioning for longer periods of time. the watchdog timer is always enabled after an application reset of the chip. it can be disabled and enabled at any time by exec uting the instructions diswdt and enwdt respectively. the software has to service t he watchdog timer before it overflows. if this is not the case because of a hardware or software failure, the watchdog timer overflows, generating a prewarning interrupt and then a reset request. the watchdog timer is a 16-bit timer clock ed with the system clock divided by 16,384 or 256. the watchdog timer register is 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 watchdog timer is reloaded and the prescaler is cleared. time intervals between 3.2 s and 13.42 s can be monitored (@ 80 mhz). the default watchdog timer interval after power-up is 6.5 ms (@ 10 mhz). 3.17 clock generation the clock generation unit can generate the system clock signal f sys for the xc228xm from a number of external or internal clock sources: ? external clock signals with pad voltage or core voltage levels ? external crystal or resonator using the on-chip oscillator ? on-chip clock source for oper ation without crystal/resonator ? wake-up clock (ultra-low-power) to further reduce power consumption the programmable on-chip pll with multiple prescalers generates a clock signal for maximum system performance from standard cryst als, a clock input signal, or from the on-chip clock source. see also section 4.6.2 . the oscillator watchdog (owd) generates an in terrupt if the crystal oscillator frequency falls below a certain limit or stops completely. in this ca se, the system can be supplied with an emergency clock to enable operation even after an external clock failure. all available clock signals can be output on one of two selectable pins.
xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 80 v2.1, 2011-07 3.18 parallel ports the xc228xm provides up to 119 i/o lines which are organized into 11 input/output ports and 2 input ports. all port lines are bit-ad dressable, and all input/output lines can be individually (bit-wise) configured via port cont rol registers. this co nfiguration selects the direction (input/output), push/pull or open-dra in operation, activation of pull devices, and edge characteristics (shape) and driver char acteristics (output current) of the port drivers. the i/o ports are true bidirectional ports which are switched to high impedance state when configured as inputs. during the in ternal reset, all port pins are configured as inputs without pull devices active. all port lines have alternate input or out put functions associat ed with them. these alternate functions can be programmed to be assigned to various port pins to support the best utilization for a given application. for this reason, certain functions appear several times in table 10 . all port lines that are not used for alternate functions may be used as general purpose i/o lines. table 10 summary of the xc228xm?s ports port width i/o connected modules p0 8 i/o ebc (a7?a0), ccu6, usic, can p1 8 i/o ebc (a15?a8), ccu6, usic p2 14 i/o ebc (ready, bhe , a23?a16, ad15?ad13, d15?d13), can, cc2, gpt12e, usic, dap/jtag p3 8 i/o can, usic p4 8 i/o ebc (cs3 ?cs0 ), cc2, can, gpt12e, usic p5 16 i analog inputs, ccu6, dap/jtag, gpt12e, can p6 4 i/o adc, can, gpt12e p7 5 i/o can, gpt12e, scu, dap/jtag, ccu6, adc, usic p8 7 i/o ccu6, dap/jtag, usic p9 8 i/o ccu6, dap/jtag, can p10 16 i/o ebc (ale, rd , wr , ad12?ad0, d12?d0), ccu6, usic, dap/jtag, can p11 6 i/o ccu6, usic, can p15 8 i analog inputs, gpt12e
xc2287m, xc2286m, xc2285m xc2000 family / base line functional description data sheet 81 v2.1, 2011-07 3.19 power management the xc228xm provides the means to control the power it consumes either at a given time or averaged over a certain duration. three mechanisms can be used (and partly in parallel): ? supply voltage management permits the temporary reduction of the supply voltage of major parts of the logic or even its comp lete disconnection. this drastically reduces the power consumed because it eliminat es leakage current, particularly at high temperature. several power reduction modes provide th e best balance of power reduction and wake-up time. ? clock generation management controls the frequency of internal and external clock signals. clock signals for currently inactive parts of logic are disabled automatically. the user can drastically reduce the consumed power by reducing the xc228xm system clock frequency. external circuits can be controlled using the programmable frequency output extclk. ? peripheral management permits temporary disabling of peripheral modules. each peripheral can be disabled and enabled separ ately. the cpu can be switched off while the peripherals can continue to operate. wake-up from power reduction modes can be triggered either externally with signals generated by the external system, or inter nally by the on-chip wake-up timer. this supports intermittent opera tion of the xc228xm by generating cyclic wake-up signals. full performance is available to quickly react to action requests while the intermittent sleep phases greatly reduce the av erage system power consumption. note: when selecting the supply voltage and the clock source and generation method, the required parameters must be carefully wr itten to the respective bitfields, to avoid unintended intermediate states. recommended sequences are provided which ensure the intended operation of power supply system and clock system. please refer to th e programmer?s guide.

xc2287m, xc2286m, xc2285m xc2000 family / base line electrical parameters data sheet 111 v2.1, 2011-07 4.6.2 definition of internal timing the internal operation of the xc228xm is controlled by the internal system clock f sys . because the system clock signal f sys can be generated from a number of internal and external sources using different mechanisms, the duration of the system clock periods (tcss) and their variation (as well as the derived external timing) depend on the mechanism used to generate f sys . this must be considered when calculating the timing for the xc228xm. figure 19 generation mechanisms for the system clock note: the example of pll operation shown in figure 19 uses a pll factor of 1:4; the example of prescaler operation us es a divider factor of 2:1. the specification of the external timing (ac characteristics) depends on the period of the system clock (tcs). m c _ xc 2 x_ cl oc kgen phase locked loop operation (1:n) f in direct clock drive (1:1) prescaler operation (n:1) f sys f in f sys f in f sys tcs tcs tcs

xc2287m, xc2286m, xc2285m xc2000 family / base line electrical parameters data sheet 113 v2.1, 2011-07 the timing in the ac characteristics refers to tcss. timing must be calculated using the minimum tcs possible under the given circumstances. the actual minimum value for tcs depends on the jitter of the pll. because the pll is constantly adjusting its output frequency to correspond to the input frequency (from crystal or oscillator), the accumulated jitter is limited. this means that the relative deviation for periods of more than one tcs is lower than for a single tcs (see formulas and figure 20 ). this is especially important for bus cycles using waitstates and 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 clo ck is divided by the output prescaler k2 to generate the system clock signal f sys . the number of vco cycles is k2 t , where t is the number of consecutive f sys cycles (tcs). the maximum accumulated jitter (long-term jitter) d tmax is defined by: d tmax [ns] = (220 / (k2 f sys ) + 4.3) this maximum value is applicable, if either the number of clock cycles t > ( f sys / 1.2) or the prescaler value k2 > 17. in all other cases for a timeframe of t tcs the accumulated jitter d t is determined by: d t [ns] = d tmax [(1 - 0.058 k2) (t - 1) / (0.83 f sys - 1) + 0.058 k2] f sys in [mhz] in all formulas. example, for a period of 3 tcss @ 33 mhz and k2 = 4: d max = (220 / (4 33) + 4.3) = 5.97 ns (not applicable directly in this case!) d 3 = 5.97 [(1 - 0.058 4) (3 - 1) / (0.83 33 - 1) + 0.058 4] = 5.97 [0.768 2 / 26.39 + 0.232] = 1.7 ns example, for a period of 3 tcss @ 33 mhz and k2 = 2: d max = (220 / (2 33) + 4.3) = 7.63 ns (not applicable directly in this case!) d 3 = 7.63 [(1 - 0.058 2) (3 - 1) / (0.83 33 - 1) + 0.058 2] = 7.63 [0.884 2 / 26.39 + 0.116] = 1.4 ns
