It is bit-wise programmable for input or output via direction bits. For a pin configured as input, the output driver is put into high-impedance state. In case of an external bus configuration, PORT0 serves as the address (A) and address/data (AD) bus in multiplexed bus modes.

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 C164SV 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. 5 V1.0, 2003-04 C164SV Preliminary Table 2 Pin Definitions and Functions (cont’d) Symbol Pin No. Input Outp. Function RSTIN I/O Reset Input with Schmitt-Trigger characteristics. A low level at this pin while the oscillator is running resets the C164SV. An internal pullup resistor permits power-on reset using only a capacitor connected to VSS. A spike filter suppresses 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. In bidirectional reset mode (enabled by setting bit BDRSTEN in register SYSCON) the RSTIN line is internally pulled low for the duration of the internal reset sequence upon any reset (HW, SW, WDT). See note below this table. 27 Note: To let the reset configuration of PORT0 settle and to let the PLL lock a reset duration of ca. 1 ms is recommended. Data Sheet 6 V1.0, 2003-04 C164SV Preliminary Table 2 Pin Definitions and Functions (cont’d) Symbol Pin No. Input Outp. Function P20 IO Port 20 is a 6-bit bidirectional I/O port (no P20.5 output driver in the OTP versions). It is bit-wise programmable for input or output via direction bits. For a pin configured as input, the output driver is put into high-impedance state. The following Port 20 pins also serve for alternate functions: RD External Memory Read Strobe, activated for every external instruction or data read access. External Memory Write Strobe, activated for WR every external data write access. ALE Address Latch Enable Output. Can be used for latching the address into external memory or an address latch in the multiplexed bus modes. External Access Enable pin. EA A low level at this pin during and after Reset forces the C164SV to latch the configuration from PORT0 and pin RD, and to begin instruction execution out of external memory. A high level forces the C164SV to latch the configuration from pins RD, ALE, and WR, and to begin instruction execution out of the internal program memory. “ROMless” versions must have this pin tied to ‘0’. CLKOUT System Clock Output (= CPU Clock), FOUT Programmable Frequency Output RSTOUT Internal Reset Indication Output. This pin is set to a low level when the part is executing either a hardware-, a software- or a watchdog timer reset. RSTOUT remains low until the EINIT (end of initialization) instruction is executed.

Data Sheet 9 V1.0, 2003-04 C164SV Preliminary Note: The following behavior differences must be observed when the bidirectional reset is active: • Bit BDRSTEN in register SYSCON cannot be changed after EINIT and is cleared automatically after a reset. • The reset indication flags always indicate a long hardware reset. • The PORT0 configuration is treated as if it were a hardware reset. In particular, the bootstrap loader may be activated when P0L.4 is low. • Pin RSTIN may only be connected to external reset devices with an open drain output driver. • A short hardware reset is extended to the duration of the internal reset sequence. Data Sheet 10 V1.0, 2003-04 C164SV Preliminary Functional Description The architecture of the C164SV combines advantages of both RISC and CISC processors and of advanced peripheral subsystems in a very well-balanced way. In addition the on-chip memory blocks allow the design of compact systems with maximum performance. The following block diagram gives an overview of the different on-chip components and of the advanced, high bandwidth internal bus structure of the C164SV. Note: All time specifications refer to a CPU clock of 25 MHz (see definition in the AC Characteristics section).

A fourth bus, the XBUS, connects external resources as well as additional on-chip resoures, the X-Peripherals (see Figure 3). Data Sheet 11 V1.0, 2003-04 C164SV Preliminary Memory Organization The memory space of the C164SV 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 bitaddressable. The C164SV incorporates 16 Kbytes of on-chip mask-programmable ROM (not in the ROM-less derivative, of course) for code or constant data. The on-chip ROM can be mapped either to segment 0 or segment 1. 1 Kbyte of on-chip Internal RAM (IRAM) 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 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 64 Kbytes of external RAM and/or ROM can be connected to the microcontroller. Data Sheet 12 V1.0, 2003-04 C164SV Preliminary 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 two different external memory access modes, which are as follows: – 16-bit Addresses, 16-bit Data, Multiplexed – 11-bit Addresses, 8-bit Data, Multiplexed 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 control the access to 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. Note: The programmable bus features and the window mechanism are standard features of the C166 architecture. Due to the C164SV’s limited external address space, however, they can be utilized only to a small extend. The C164SV will preferably be used in single-chip mode. Applications which require access to external resources such as peripherals or small memories, will use the 8-bit data bus with 11-bit address bus in most cases. In this case the upper pins of PORT0 can be used for the serial interfaces. If a wider address or a 16-bit data bus is required the serial interfaces cannot be used. Data Sheet 13 V1.0, 2003-04 C164SV Preliminary 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 C164SV’s instructions can be executed in just one machine cycle which requires 2 CPU clocks (4 TCL). 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’, reduces the execution time of repeatedly performed jumps in a loop from 2 cycles to 1 cycle. Figure 4 Data Sheet CPU Block Diagram 14 V1.0, 2003-04 C164SV Preliminary The CPU has a register context consisting of up to 16 wordwide GPRs at its disposal. These 16 GPRs 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 any 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 C164SV instruction set which includes the following instruction classes: – – – – – – – – – – – – 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. Data Sheet 15 V1.0, 2003-04 C164SV Preliminary Interrupt System With an interrupt response time within a range from just 5 to 12 CPU clocks (in case of internal program execution), the C164SV is capable of reacting very fast to the occurrence of non-deterministic events. The architecture of the C164SV 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 C164SV 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.

Hardware traps cause immediate non-maskable system reaction which is similar to a standard interrupt service (branching to a dedicated vector table location). The occurrence 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. Table 4 shows all of the possible exceptions or error conditions that can arise during runtime: Table 4 Hardware Trap Summary Exception Condition Trap Flag Reset Functions: – Hardware Reset – Software Reset – W-dog Timer Overflow – Class A Hardware Traps: – Non-Maskable Interrupt NMI – Stack Overflow STKOF – Stack Underflow STKUF Class B Hardware Traps: – Undefined Opcode – Protected Instruction Fault – Illegal Word Operand Access – Illegal Instruction Access – Illegal External Bus Access Trap Vector Vector Location Trap Number Trap Priority RESET RESET RESET 00’0000H 00’0000H 00’0000H 00H 00H 00H III III III NMITRAP 00’0008H STOTRAP 00’0010H STUTRAP 00’0018H 02H 04H 06H II II II UNDOPC BTRAP PRTFLT BTRAP 00’0028H 00’0028H 0AH 0AH I I ILLOPA BTRAP 00’0028H 0AH I ILLINA BTRAP 00’0028H 0AH I ILLBUS BTRAP 00’0028H 0AH I Reserved – – [2CH – 3CH] [0BH – 0FH] – Software Traps – TRAP Instruction – – Any Any [00’0000H – [00H – 00’01FCH] 7FH] in steps of 4H Data Sheet 19 Current CPU Priority V1.0, 2003-04 C164SV Preliminary The Capture/Compare Unit CAPCOM2 The general purpose CAPCOM2 unit supports generation and control of timing sequences on up to 12 channels with a maximum resolution of 16 TCL. 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 recording relative to external events. Two 16-bit timers (T7/T8) with reload registers provide two independent time bases for the capture/compare register array. Each dual purpose capture/compare register, which may be individually allocated to either CAPCOM timer and programmed for capture or compare function, has 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 (‘capture’d) 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 taken based on the selected compare mode. Table 5 Compare Modes (CAPCOM) 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 Mode 2 Interrupt-only compare mode; only one compare interrupt per timer period is generated Mode 3 Pin set ‘1’ on match; pin reset ‘0’ on compare time overflow; only one compare event per timer period is generated Double Register Mode Two registers operate on one pin; pin toggles on each compare match; several compare events per timer period are possible.

In compare mode the CAPCOM6 unit provides two output signals per channel which have inverted polarity and non-overlapping pulse transitions. 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 12 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 CPU clock.

Figure 5 CAPCOM6 Block Diagram For motor control applications both subunits may generate versatile multichannel PWM signals which are basically either controlled by compare timer 12 or by a typical hall sensor pattern at the interrupt inputs (block commutation). Data Sheet 21 V1.0, 2003-04 C164SV Preliminary 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 three 16-bit timers. Each timer may operate independently in a number of different modes, or may be concatenated with another timer. Each of the three timers T2, T3, T4 of module GPT1 can be configured individually for one of four basic modes of operation, which are Timer, Gated Timer, Counter, and Incremental Interface Mode. In Timer Mode, the 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 16 TCL. 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 timers (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 overflow/underflow. The state of this latch may 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.

The RTC module is directly clocked with the on-chip oscillator frequency divided by 32 via a separate clock driver (fRTC = fOSC/32) and is therefore independent from the selected clock generation mode of the C164SV. All timers count up. The RTC module can be used for different purposes: • System clock to determine the current time and date • Cyclic time based interrupt • 48-bit timer for long term measurements T14REL Reload T14 8:1 f RTC Interrupt Request RTCH RTCL MCD04432 Figure 7 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 resets are executed. Data Sheet 24 V1.0, 2003-04 C164SV Preliminary A/D Converter For analog signal measurement, a 10-bit/12-bit A/D converter with 8 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 and can so be adjusted to the external circuitry. 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 than 8 analog input channels, the remaining channel inputs can be used as digital input port pins. The A/D converter of the C164SV supports four 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 (standard or extension) are sequentially sampled and converted. In the Auto Scan Continuous mode, the number of prespecified channels is 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 interrupt 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. temperature) and compensates process variations. These calibration cycles are part of the conversion 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 disconnected 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). Data Sheet 25 V1.0, 2003-04 C164SV Preliminary 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 High-Speed Synchronous Serial Channel (SSC). The ASC0 is upward compatible with the serial ports of the Infineon 8-bit microcontroller families and supports full-duplex asynchronous communication at up to 781 kbit/s and half-duplex synchronous communication at up to 3.1 Mbit/s (@ 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 SSC supports full-duplex synchronous communication at up to 6.25 Mbit/s (@ 25 MHz CPU clock). It may be configured so it interfaces with serially linked peripheral components. A dedicated baud rate generator allows to set up all standard baud rates without oscillator tuning. For transmission, reception and error handling 3 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 and receive error supervise the correct handling of the data buffer. Phase and baudrate error detect incorrect serial data. Data Sheet 26 V1.0, 2003-04 C164SV Preliminary 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 chip’s 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 by 2/4/128/ 256. 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 µs and 336 ms can be monitored (@ 25 MHz). The default Watchdog Timer interval after reset is 5.24 ms (@ 25 MHz). Parallel Ports The C164SV provides up to 50 I/O lines which are organized into four 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 Port 8 can be configured (pin by pin) for push/ pull operation or open-drain operation via a control register. During the internal reset, all port pins are configured as inputs. All port lines have programmable alternate input or output functions associated with them. All port lines that are not used for these alternate functions may be used as general purpose IO lines. PORT0 may be used as address and data lines when accessing external memory. Also the serial interfaces ASC0 and SSC use the upper pins of P0H. Ports P1L, P1H, and P8 are associated with the capture inputs or compare outputs of the CAPCOM units and/or serve as external interrupt inputs. Port 5 is used for the analog input channels to the A/D converter or timer control signals. Port 20 includes the bus control signals RD, WR, ALE, the configuration input EA, the the system control output RSTOUT, and the system clock output CLKOUT (or the programmable frequency output FOUT). The edge characteristics (transition time) and driver characteristics (output current) of the C164SV’s port drivers can be selected via the Port Output Control registers (POCONx). Data Sheet 27 V1.0, 2003-04 C164SV Preliminary Oscillator Watchdog 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. In direct drive mode the PLL base frequency is used directly (fCPU = 2 … 5 MHz). In prescaler mode the PLL base frequency is divided by 2 (fCPU = 1 … 2.5 MHz). Note: The CPU clock source is only switched back to the oscillator clock after a hardware reset. The oscillator watchdog can be disabled by setting bit OWDDIS in register SYSCON. In this case (OWDDIS = ‘1’) the PLL remains idle and provides no clock signal, while the CPU clock signal is derived directly from the oscillator clock or via prescaler or SDD. Also no interrupt request will be generated in case of a missing oscillator clock. Note: At the end of a reset bit OWDDIS reflects the inverted level of pin RD at that time. Thus the oscillator watchdog may also be disabled via hardware by (externally) pulling the RD line low upon a reset, similar to the standard reset configuration via PORT0. Data Sheet 28 V1.0, 2003-04 C164SV Preliminary Power Management The C164SV provides several means to control the power it consumes either at a given time or averaged over a certain timespan. Three mechanisms can be used (partly in parallel): • Power Saving Modes switch the C164SV 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 (control via register SYSCON2). Slow Down Mode lets the C164SV run at a CPU clock frequency of fOSC/1 … 32 (half for prescaler operation) which drastically reduces the consumed power. The PLL can be optionally disabled while operating in Slow Down Mode. 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. A group control option disables a major part of the peripheral set by setting one single bit. The on-chip RTC supports intermittend operation of the C164SV by generating cyclic wakeup 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.

An SFR can be specified via its individual mnemonic name. Depending on the selected addressing mode, an SFR can be accessed via its physical address (using the Data Page Pointers), or via its short 8-bit address (without using the Data Page Pointers).

For signal levels outside these specifications also refer to the specification of the overload current IOV. 2) For pin RSTIN this specification is only valid in bidirectional reset mode. 3) The maximum deliverable output current of a port driver depends on the selected output driver mode, see Table 10, Current Limits for Port Output Drivers.

However, only the levels for nominal output currents are guaranteed. 5) This specification is not valid for outputs which are switched to open drain mode.

These parameters are tested at VDDmax and maximum CPU clock with all outputs disconnected and all inputs at VIL or VIH. 2) This parameter is determined mainly by the current consumed by the oscillator (see Figure 8). This current, however, is influenced by the external oscillator circuitry (crystal, capacitors). The values given refer to a typical circuitry and may change in case of a not optimized external oscillator circuitry. 3) This parameter is tested including leakage currents.

Both edges of the CPU clock can trigger internal (e.g. pipeline) or external (e.g. 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 10). Phase Locked Loop Operation fOSC TCL fCPU TCL Direct Clock Drive fOSC TCL fCPU TCL Prescaler Operation fOSC TCL fCPU TCL Figure 10 MCT04338 Generation Mechanisms for the CPU Clock The CPU clock signal fCPU can be generated from the oscillator clock signal fOSC via different mechanisms. The duration of TCLs and their variation (and also the derived external timing) depends on the used mechanism to generate fCPU. This influence must be regarded when calculating the timings for the C164SV. Note: The example for PLL operation shown in Figure 10 refers to a PLL factor of 4. The used mechanism to generate the basic CPU clock is selected by bitfield CLKCFG in register RP0H.7-5. Upon a long hardware reset register RP0H is loaded with the logic levels present on the upper half of PORT0 (P0H), i.e. bitfield CLKCFG represents the logic levels on pins Data Sheet 45 V1.0, 2003-04 C164SV Preliminary P0.15-13 (P0H.7-5). Register RP0H can be loaded from the upper half of register RSTCON under software control. Table 11 associates the combinations of these three bits with the respective clock generation mode.

Prescaler Operation When prescaler operation is configured (CLKCFG = 001B) the CPU clock is derived from the internal oscillator (input clock signal) by a 2:1 prescaler. The frequency of fCPU is half the frequency of fOSC and the high and low time of fCPU (i.e. the duration of an individual TCL) is defined by the period of the input clock fOSC. The timings listed in the AC Characteristics that refer to TCLs therefore can be calculated using the period of fOSC for any TCL. Phase Locked Loop When PLL operation is configured (via CLKCFG) the on-chip phase locked loop is enabled and provides the CPU clock (see Table 11). The PLL multiplies the input frequency by the factor F which is selected via the combination of bits RP0H.7-5 (i.e. fCPU = fOSC × F). With every F’th transition of fOSC the PLL circuit synchronizes the CPU clock to the input clock. This synchronization is done smoothly, i.e. the CPU clock frequency does not change abruptly. Data Sheet 46 V1.0, 2003-04 C164SV Preliminary Due to this adaptation to the input clock the frequency of fCPU is constantly adjusted so it is locked to fOSC. The slight variation causes a jitter of fCPU 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 11). For a period of N × TCL the minimum value is computed using the corresponding deviation DN: (N × TCL)min = N × TCLNOM - DN; DN [ns] = ±(13.3 + N × 6.3)/fCPU [MHz], where N = number of consecutive TCLs and 1 ≤ N ≤ 40. So for a period of 3 TCLs @ 25 MHz (i.e. N = 3): D3 = (13.3 + 3 × 6.3)/25 = 1.288 ns, and (3TCL)min = 3TCLNOM - 1.288 ns = 58.7 ns (@ fCPU = 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 11). Max. jitter DN ns ±30 This approximated formula is valid for 1< –N< – 40 and 10 MHz < – fCPU < – 25 MHz. 10 MHz ±26.5 ±20 16 MHz 20 MHz 25 MHz ±10 ±1 1 10 20 30 40 N MCD04455 Figure 11 Data Sheet Approximated Maximum Accumulated PLL Jitter 47 V1.0, 2003-04 C164SV Preliminary Direct Drive When direct drive is configured (CLKCFG = 011B) 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 fCPU directly follows the frequency of fOSC so the high and low time of fCPU (i.e. the duration of an individual TCL) is defined by the duty cycle of the input clock fOSC. 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: TCLmin = 1/fOSC × DCmin (DC = duty cycle) For two consecutive TCLs the deviation caused by the duty cycle of fOSC is compensated so the duration of 2TCL is always 1/fOSC. The minimum value TCLmin 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/fOSC.

It is strongly recommended to measure the oscillation allowance (or margin) in the final target system (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).

However, the conversion result in these cases will be X000H or X3FFH, respectively. 2) The limit values for fBC must not be exceeded when selecting the CPU frequency and the ADCTC setting. 3) This parameter includes the sample time tS, the time for determining the digital result and the time to load the result register with the conversion result. Values for the basic clock tBC depend on programming and can be taken from Table 14. This parameter depends on the ADC control logic. It is not a real maximum value, but rather a fixum. 4) For 12-bit conversions the CPU clock frequency must be limited to fCPU ≤ 20 MHz to achieve the specified TUE limits. 5) During the reset calibration conversions can be executed (with the current accuracy). The time required for these conversions is added to the total reset calibration time. 6) TUE is tested at VAREF = VDD + 0.1 V, VAGND = 0 V. It is guaranteed by design for all other voltages within the defined voltage range. The specified TUE is guaranteed only if the absolute sum of input overload currents on Port 5 pins (see IOV specification) does not exceed 10 mA. During the reset calibration sequence the TUE may reach twice the indicated maximum value. Data Sheet 50 V1.0, 2003-04 C164SV Preliminary 7) If the analog reference supply voltage exceeds the power supply voltage by up to 0.2 V (i.e. VAREF = VDD + 0.2 V) the maximum TUE is increased to ±3 LSB. This range is not 100% tested. 8) During the conversion the ADC’s capacitance must be repeatedly charged or discharged. The internal resistance of the reference voltage source must allow the capacitance to reach its respective voltage level within each conversion step. The maximum internal resistance results from the programmed conversion timing. 9) Not 100% tested, guaranteed by design and characterization. 10) During the sample time the input capacitance CAIN can be charged/discharged by the external source. The internal resistance of the analog source must allow the capacitance to reach its final voltage level within tS. After the end of the sample time tS, changes of the analog input voltage have no effect on the conversion result. Values for the sample time tS depend on programming and can be taken from Table 14. Sample time and conversion time of the C164SV’s A/D Converter are programmable. Table 14 should be used to calculate the above timings. The limit values for fBC must not be exceeded when selecting ADCTC.
