crystal (in conjunc-tion with CKO).See Oscillator description.RESET is the master reset input.See Reset description.PORT I is a 4-bit Hi-Z input port.PORT L is an 8-bit I/O port.There are two registers associated with the L port:a data register and a configuration register.Therefore,each L I/O bit can be individually configured under software control as shown below:Port L Port L Port L Config.Data Setup00Hi-Z Input (TRI-STATE)01Input with Weak Pull-up 10Push-pull Zero Output 11Push-pull One OutputThree data memory address locations are allocated for this port,one each for data register [00D0],configuration register [00D1]and the input pins [00D2].Port L has the following alternate features:L7MIWU or MODOUT (high sink current capability)L6MIWU (high sink current capability)L5MIWU (high sink current capability)L4MIWU (high sink current capability)L3MIWUL2MIWU or CMPIN+L1MIWU or CMPIN−L0MIWU or CMPOUTThe selection of alternate Port L functions is done through registers WKEN [00C9]to enable MIWU and CNTRL2[00CC]to enable comparator and modulator.All eight L-pins have Schmitt Triggers on their inputs.PORT G is an 8-bit port with 6I/O pins (G0–G5)and 2input pins (G6,G7).All eight G-pins have Schmitt Triggers on the inputs.There are two registers associated with the G port:a data register and a configuration register.Therefore each G port bit can be individually configured under software control as shown below:Port G Port G Port G Config.Data Setup00Hi-Z Input (TRI-STATE)01Input with Weak Pull-up 10Push-pull Zero Output 11Push-pull One OutputThree data memory address locations are allocated for this port,one for data register [00D4],one for configuration reg-ister [00D5]and one for the input pins [00D6].Since G6and G7are Hi-Z input only pins,any attempt by the user to con-figure them as outputs by writing a one to the configuration register will be disregarded.Reading the G6and G7configu-ration bits will return zeros.Note that the device will be placed in the Halt mode by writing a “1”to the G7data bit.Six pins of Port G have alternate features:G7CKO crystal oscillator output (selected by mask option)or HALT restart input/general purpose input (if clock option is R/C or external clock)G6SI (MICROWIRE serial data input)G5SK (MICROWIRE clock I/O)G4SO (MICROWIRE serial data output)G3TIO (timer/counter input/output)G0INTR (an external interrupt)Pins G2and G1currently do not have any alternate func-tions.The selection of alternate Port G functions are done through registers PSW [00EF]to enable external interrupt and CN-TRL1[00EE]to select TIO and MICROWIRE operations.PORT D is a four bit output port that is preset when RESET goes low.One data memory address location is allocated for the data register [00DC].Note:Care must be exercised with the D2pin operation.At RESET,the ex-ternal loads on this pin must ensure that the output voltages stay above 0.8V CC to prevent the chip from entering special modes.Also keep the external loading on D2to less than 1000pF.Functional DescriptionThe internal architecture is shown in the block diagram.Data paths are illustrated in simplified form to depict how the vari-ous logic elements communicate with each other in imple-menting the instruction set of the device.ALU and CPU RegistersThe ALU can do an 8-bit addition,subtraction,logical or shift operations in one cycle time.There are five CPU registers:A is the 8-bit Accumulator registerPC is the 15-bit Program Counter registerPU is the upper 7bits of the program counter (PC)PL is the lower 8bits of the program counter (PC)B is the 8-bit address register and can be auto incre-mented or decremented.X is the 8-bit alternate address register and can be autoincremented or decremented.SP is the 8-bit stack pointer which points to the subroutinestack (in RAM).B,X and SP registers are mapped into the on chip RAM.The B and X registers are used to address the on chip RAM.The SP register is used to address the stack in RAM during sub-routine calls and returns.The SP must be preset by software upon initialization.MemoryThe memory is separated into two memory spaces:program and data.PROGRAM MEMORYProgram memory consists of 1024x 8ROM or 2048x 8ROM.These bytes of ROM may be instructions or constant data.The memory is addressed by the 15-bit program counter (PC).ROM can be indirectly read by the LAID in-struction for table lookup.DATA MEMORYThe data memory address space includes on chip RAM,I/O and registers.Data memory is addressed directly by the in-struction or indirectly through B,X and SP registers.The de-vice has 64or 128bytes of RAM.Sixteen bytes of RAM areC O P 820C J /C O P 840C J F a m i l y10Memory(Continued)mapped as“registers”,these can be loaded immediately, decremented and tested.Three specific registers:X,B,and SP are mapped into this space,the other registers are avail-able for general usage.Any bit of data memory can be directly set,reset or tested. All I/O and registers(except A and PC)are memory mapped; therefore,I/O bits and register bits can be directly and indi-vidually set,reset and tested,except the write once only bit (WDREN,WATCHDOG Reset Enable),and the unused and read only bits in CNTRL2and WDREG registers.Note:RAM contents are undefined upon power-up.ResetEXTERNAL RESETThe RESET input pin when pulled low initializes the micro-controller.The user must insure that the RESET pin is held low until V CC is within the specified voltage range and the clock is stabilized.An R/C circuit with a delay5x greater than the power supply rise time is recommended(Figure4). The device immediately goes into reset state when the RE-SET input goes low.When the RESET pin goes high the de-vice comes out of reset state synchronously.The device will be running within two instruction cycles of the RESET pin go-ing high.The following actions occur upon reset:Port L TRI-STATEPort G TRI-STATEPort D HIGHPC CLEAREDRAM Contents RANDOM with Power-On-ResetUNAFFECTED with

CLEAREDWATCHDOG Timer Prescaler/Counter eachloaded with FFThe device comes out of the HALT mode when the RESET pin is pulled low.In this case,the user has to ensure that the RESET signal is low long enough to allow the oscillator to re-start.An internal256t c delay is normally used in conjunction with the two pin crystal oscillator.When the device comes out of the HALT mode through Multi-Input Wakeup,this de-lay allows the oscillator to stabilize.The following additional actions occur after the device comes out of the HALT mode through the RESET pin.If a two pin crystal/resonator oscillator is being used:RAM Contents UNCHANGEDTimer T1and A Contents UNKNOWN WATCHDOG Timer Prescaler/Counter ALTEREDIf the external or RC Clock option is being used:RAM Contents UNCHANGEDTimer T1and A Contents

Brown Out condition),the external reset will not oc-cur until the Brown Out condition is removed.External reset has prior-ity only if V CC is greater than the Brown Out voltage.WATCHDOG RESETWith WATCHDOG enabled,the WATCHDOG logic resetsthe device if the user program does not service the WATCH-DOG timer within the selected service window.The WATCH-DOG reset does not disable the WATCHDOG.Upon WATCHDOG reset,the WATCHDOG Prescaler and Counterare each initialized with FF Hex.The following actions occur upon WATCHDOG reset that are different from external reset.WDREN WATCHDOG Reset Enable bit

Brown Out protection circuit resets the device when the operating voltage (V CC )is lower than the Brown Out voltage.The device is held in reset when V CC stays be-low the Brown Out Voltage.The device will remain in RESET as long as V CC is below the Brown Out Voltage.The Device will resume execution if V CC rises above the Brown Out Volt-age.If a two pin crystal/resonator clock option is selected,the Brown Out reset will trigger a 256tc delay.This delay al-lows the oscillator to stabilize before the device exits the re-set state.The delay is not used if the clock option is either R/C or external clock.The contents of data registers and RAM are unknown following a Brown Out reset.The external reset takes priority over Brown Out Reset and will deactivate the 256t c cycles delay if in progress.The Brown Out reset takes priority over the WATCHDOG reset.The following actions occur as a result of Brown Out reset:Port L TRI-STATE Port G TRI-STATE Port D HIGH PCCLEARED RAM Contents

OUT RESET ex-ternally and will force the RESET pin low.The Development System does not emulate the 256tc delay.Brown Out DetectionAn on-board detection circuit monitors the operating voltage (V CC )and compares it with the minimum operating voltage specified.The Brown Out circuit is designed to reset the de-vice if the operating voltage is below the Brown Out voltage (between 1.8V to 4.2V at −40˚C to +85˚C).The Minimum op-erating voltage for the device is 2.5V with Brown Out dis-abled,but with BROWN OUT enabled the device is guaran-teed to operate properly down to minimum Brown Outvoltage (Max frequency 4MHz),For temperature range of 0˚C to 70˚C the Brown Out voltage is expected to be be-tween 1.9V to 3.9V.The circuit can be enabled or disabled by Brown Out mask option.If the device is intended to oper-ate at lower V CC (lower than Brown Out voltage VBO max),the Brown Out circuit should be disabled by the mask option.The Brown Out circuit may be used as a power-up reset pro-vided the power supply rise time is slower than 50µs (0V to 6.0V).Brown Out should not be used at frequencies over 4MHz (COP840CJ).Note:Brown Out Circuit is active in HALT mode (with the Brown Out maskoption selected).Oscillator CircuitsEXTERNAL OSCILLATORCKI can be driven by an external clock signal provided it meets the specified duty cycle,rise and fall times,and input levels.G7/CKO is available as a general purpose input G7and/or Halt control.CRYSTAL OSCILLATORBy selecting G7/CKO as a clock output,CKI and G7/CKO can be connected to create a crystal controlled oscillator.Table 1shows the component values required for various standard crystal values.R/C OSCILLATOR (COP820CJ)For COP820CJ,selecting CKI as a single pin oscillator,CKI can make a R/C oscillator.G7/CKO is available as a general purpose input and/or HALT control.Table 2shows variation in the oscillator frequencies as functions of the component (R and C)values.TABLE 1.Crystal Oscillator

V.The capacitor is on-chip.The G7/CKO pin is available as a general purpose input G7and/or Halt control.Adding an external capacitor will jeopardize the clock frequency toler-ance and increase EMI emissions.Table3shows the clock frequency for the different resistor values.TABLE3.RC Oscillator Configuration(Part-To-Part Variation)R(kΩ)CK1Freq.(MHz)Temperature V CC2.27.0±15%-40˚C to+85˚C 4.5V

important to take this into account when figuring the clock frequency.HALT ModeThe device is a fully static device.The device enters the HALT mode by writing a one to the G7bit of the G data reg-ister.Once in the HALT mode,the internal circuitry does not receive any clock signal and is therefore frozen in the exact state it was in when halted.In this mode,the chip will only draw leakage current(output current and DC current due to the Brown Out circuit if Brown Out is enabled).The device supports four different methods of exiting the HALT mode.The first method is with a low to high transition on the CKO(G7)pin.This method precludes the use of the crystal clock configuration(since CKO is a dedicated out-put).It may be used either with an RC clock configuration or an external clock configuration.The second method of exit-ing the HALT mode is with the multi-Input Wakeup feature on the L port.The third method of exiting the HALT mode is by pulling the RESET input low.The fourth method is with the operating voltage going below Brown Out voltage(if Brown Out is enabled by mask option).If the two pin crystal/resonator oscillator is being used and Multi-Input Wakeup or Brown Out causes the device to exit the HALT mode,the WAKEUP signal does not allow the chip to start running immediately since crystal oscillators have a delayed start up time to reach full amplitude and freuqency stability.The WATCHDOG timer(consisting of an8-bit pres-caler followed by an8-bit counter)is used to generate a fixed delay of256tc to ensure that the oscillator has indeed stabi-lized before allowing instruction execution.In this case,upon detecting a valid WAKEUP signal only the oscillator circuitry is enabled.The WATCHDOG Counter and Prescaler are each loaded with a value of FF Hex.The WATCHDOG pres-caler is clocked with the t c instruction cycle.(The t c clock is derived by dividing the oscillator clock down by a factor of 10).The Schmitt trigger following the CKI inverter on the chip ensures that the WATCHDOG timer is clocked only when the oscillator has a sufficiently large amplitude to meet the Schmitt trigger specs.This Schmitt trigger is not part of the oscillator closed loop.The start-up timeout from the WATCH-DOG timer enables the clock signals to be routed to the rest of the chip.The delay is not activated when the device comes out of HALT mode through RESET pin.Also,if the clock option is either RC or External clock,the delay is notused,but the WATCHDOG Prescaler/Counter contents are changed.The Development System will not emulate the256tc delay.The RESET pin or Brown Out will cause the device to resetand start executing from address X’0000.A low to high tran-sition on the G7pin(if single pin oscillator is used)orMulti-Input Wakeup will cause the device to start executingfrom the address following the HALT instruction.When RESET pin is used to exit the device from the HALTmode and the two pin crystal/resonator(CKI/CKO)clock op-tion is selected,the contents of the Accumulator and theTimer T1are undetermined following the reset.All other in-formation except the WATCHDOG Prescaler/Counter con-tents is retained until continuing.If the device comes out ofthe HALT mode through Brown Out reset,the contents ofdata registers and RAM are unknown following the reset.All information except the WATCHDOG Prescaler/Counter con-tents is retained if the device exits the HALT mode throughG7pin or Multi-Input Wakeup.G7is the HALT-restart pin,but it can still be used as an input.If the device is not halted,G7can be used as a general pur-pose input.If the Brown Out Enable mask option is selected,the BrownOut circuit remains active during the HALT mode causing ad-ditional current to be drawn.Note:To allow clock resynchronization,it is necessary to program two NOP’s immediately after the device comes out of the HALT mode.The usermust program two NOP’s following the“enter HALT mode”(set G7data bit)instruction.MICROWIRE/PLUSMICROWIRE/PLUS is a serial synchronous bidirectional communications interface.The MICROWIRE/PLUS capabil-ity enables the device to interface with any of National Semi-conductor’s MICROWIRE peripherals(i.e.A/D converters,display drivers,EEPROMS,etc.)and with other microcon-trollers which support the MICROWIRE/PLUS interface.It consists of an8-bit serial shift register(SIO)with serial dataCOP820CJ/COP840CJFamily。
