Product Specification (V0.98) 04.03.2006 Contents 6.1 Operational Registers 6.1.1 R0 (Indirect Address Register) R0 is not a physically implemented register. Its major function is to perform as an indirect address pointer. Any instruction using R0 as a pointer, actually accesses the data pointed by the RAM Select Register (R4). 6.1.2 R1 (Time Clock /Counter) Increased by an external signal edge through the TCC pin, or by the instruction cycle clock. External signal of TCC trigger pulse width must be greater than one instruction. The signals to increase the counter are determined by Bit 4 and Bit 5 of the CONT register. Writable and readable as any other registers. 6.1.3 R2 (Program Counter) and Stack Reset Vector Interrupt Vector PC (A12 ~ A0) 000H 008H User Memory Space On-chip Program Memory Stack Level 1 Stack Level 2 Stack Level 3 Stack Level 8 1FFFH Fig. 6-1 Program Counter Organization R2 and hardware stacks are 12-bit wide. The structure is depicted in the table under Section 6.1.3.1 Data Memory Configuration (next section). Generates 8K×13 bits on-chip ROM addresses to the relative programming instruction codes. One program page is 1024 words long. The contents of R2 are all set to "0"s when a RESET condition occurs. Product Specification (Draft 0.98) 04.03.2006 (This specification is subject to change without further notice) • 11 Contents "JMP" instruction allows direct loading of the lower 10 program counter bits. Thus, "JMP" allows PC to jump to any location within a page. "CALL" instruction loads the lower 10 bits of the PC, and then PC+1 is pushed into the stack. Thus, the subroutine entry address can be located anywhere within a page. "RET" ("RETL k", "RETI") instruction loads the program counter with the contents of the top of stack. "ADD R2, A" allows a relative address to be added to the current PC, and the ninth and above bits of the PC will increase progressively. "MOV R2, A" allows loading of an address from the "A" register to the lower 8 bits of the PC, and the ninth and tenth bits (A8 ~ A9) of the PC will remain unchanged. Any instruction (except “ADD R2,A”) that is written to R2 (e.g., "MOV R2, A", "BC R2, 6",⋅⋅⋅⋅⋅) will cause the ninth bit and the tenth bit (A8 ~ A9) of the PC to remain unchanged. In the case of PH86P558, the most three significant bits (A12,A11 and A10) will be loaded with the content of PS2,PS1 and PS0 in the status register (R3) upon execution of a "JMP", "CALL", or any other instructions set which write to R2. All instructions are single instruction cycle (fclk/2 or fclk/4) except for the instructions that are written to R2. Note that these instructions need one or two instructions cycle as determined by Code Option Register CYES bit. 12 • Product Specification (V0.98) 04.03.2006 Contents 6.1.3.1 Data Memory Configuration REGISTER BANK0 REGISTER BANK1 REGISTER BANK2 REGISTER BANK3 Control REGISTER R5(PullLowControl1) IOC5(Port5I/Ocontrol) Address 01 R1(TCCBuffer) 02 R2(PC) 03 R3(STATUS) 04 R4(RSR,bank select) 05 R5(Port5 IO data) R5(PWMcontrol register #1) 06 R6(Port6 IO data) R6(PWMcontrolregister #2) R6(Buzzeroutput ControlRegister) R6(PullLowControl2) IOC6(Port6I/Ocontrol) 07 R7(Port7 IO data) R7(PWMtimer/counter controlregister) R7(Systemcontrol Register) R7(PullLowControl3) IOC7(Port7I/Ocontrol) 08 R8(Port8 IO data) R8(PRD1H:PWM1 period) R8(TADCinput select register) R8(PullLowControl4) IOC8(Port8I/Ocontrol) R9(ADC control register) R9(PullHighControl1) IOC9(Timer4control register) R4(7,6) (0,1) (1,0) 09 R9(Timer4control register) R9(PRD2H:PWM2 period) 0A RA (SPI read buffer) RA(PRD3H:PWM3 period) RA(ADC offset calibration RA(Pull HighControl 2) register) 0B RB(SPI writebuffer) RB(PRDL:Periodcycle ofPWM) RB(ADDATA ADCdata bit11~bit4) RB(PullHigh Control3) 0C RC(SPI status buffer) RC(DT1L:Dutycycleof PWM1) RC(ADDATA1H ADC databit11~bit8) RC(PullHigh Control4) 0D RD(SPI control buffer ) RD(DT2L:Dutycycleof PWM2) RD(ADATA1L ADC databit7~bit0) RD(TIMER1H:PWM1 timer) 0E RE(Wake-upcontrol register) RE(DT3L:Dutycycleof PWM3) RE(LVDC:LVDControl) RE(TIMER2H:PWM2 timer) 0F RF(Interrupt flag) RF(DTH:Dutycycleof PWM) RF(TIMER3H:PWM3 timer) RF(TMRL:PWMtimer) 10 : 1F 20 : 3F IOCA(Comparator Control Register ) IOCE(WDT control register) IOCF(Interrupt mask1) 16ByteCommomregister Bank0 32x8 Bank1 32x8 Bank2 32x8 Bank3 32x8 Commomregister Product Specification (Draft 0.98) 04.03.2006 (This specification is subject to change without further notice) • 13 Contents 6.1.4 R3 (Status Register) 7 6 5 4 3 2 1 0 PS2 PS1 PS0 T P Z DC C • Bits 7 (PS2) ~ 5 (PS0) Page select bits. PS2~PS0 are used to pre-select a program memory page. When executing a "JMP", "CALL", or other instructions which causes the program counter to change (e.g. MOV R2, A), PS2~PS0 are loaded into the 11th,12th and 13th bits of the program counter and select one of the available program memory pages. Note that RET (RETL, RETI) instruction does not change the PS2~PS0 bits.

The PST0 ~ PST2 bits of the CONT register are used to determine the ratio of the TCC prescaler, and the PWR0 ~ PWR2 bits of the IOCE0 register are used to determine the prescaler of WDT. The prescaler counter is cleared by the instructions each time such instructions are written into TCC. The WDT and prescaler will be cleared by the “WDTC” and “SLEP” instructions. Fig. 6-2 (next page) depicts the block diagram of TCC/WDT. TCC (R1) is an 8-bit timer/counter. The TCC clock source can be internal clock or external signal input (edge selectable from the TCC pin). If TCC signal source is from internal clock, TCC will increase by 1 at every instruction cycle (without prescaler). Referring to Fig. 6-2, CLK=Fosc/2 or CLK=Fosc/4 is dependent to the CODE Option bit <CLKS>. CLK=Fosc/2 if the CLKS bit is "0," and CLK=Fosc/4 if the CLKS bit is "1." If TCC signal source is from external clock input, TCC will increase by 1 at every falling edge or rising edge of the TCC pin. TCC pin input time length (kept in High or Low level) must be greater than 1CLK. NOTE The internal TCC will stop running when sleep mode occurs. However, during AD conversion, when TCC is set to “SLEP” instruction, if the ADWE bit of RE register is enabled, the TCC will keep on running The watchdog timer is a free running on-chip RC oscillator. The WDT will keep on running even when the oscillator driver has been turned off (i.e., in sleep mode). During normal operation or sleep mode, a WDT time-out (if enabled) will cause the device to reset. The WDT can be enabled or disabled at any time during normal mode through software programming. Refer to WDTE bit of IOCE0 register (Section 6.2.10IOCE0 (WDT Control Register).

If PH86P558 is a master controller, it sends clock through the SCK pin. A couple of 8-bit data are transmitted and received at the same time. However, if PH86P558 is defined as a slave, its SCK pin could be programmed as an input pin. Data will continue to be shifted based on both the clock rate and the selected edge. You can also set SPIS bit 7(DORD) to decide the SPI transmission order, SPIC bit3 (SDOC) to control SDO pin after serial data output status and SPIS bit 6 (TD1), bit 5 (TD0) decides the SDO status output delay times.

Overview Timer4(TMR4) is an eight-bit clock counter with a programmable prescaler. When TMR4 in SPI baud rate clock generator mode (SBRS0, SBRS1and SBRS2 a1l set to 1) and then SPI control register bit4 (SSE) set to 1. Timer4 will enable automatic without set TM4E. TMR4 can be read and written and cleared on any reset conditions. 2. Function description Fig. 3 shows TIMER4 block diagram. Each signal and block is described as follows: Set predict value TM4E 0 TMR4 value 1 Set TM4IF TMR4 up Counter In SPI baud generator mode ?

Power-on reset 56 • Product Specification (V0.98) 04.03.2006 Contents 2. /RESET pin input "low" 3. WDT time-out (if enabled). The device is kept in a RESET condition for a period of approximately 18ms (one oscillator start-up timer period) after the Power-on reset is detected. And if the /Reset pin goes “low” or WDT time-out is active, a reset is generated, the reset time is 150μs and 8clocks in high XTAL mode. In RC mode (IEC or ERC), the reset time is 10μs. In low XTAL mode, the reset time is 500ms.Once the RESET occurs, the following functions are performed. (The initial address is 000h) The oscillator continues running, or will be started (if under sleep mode) The Program Counter (R2) is set to all "0" All I/O port pins are configured as input mode (high-impedance state) The Watchdog Timer and prescaler are cleared When power is switched on, the upper 3 bits of R3 and upper 2 bits of R4 are cleared The CONT register bits are set to all "1" except for the Bit 6 (INT flag) The IOCB0 register bits are set to all "1" The IOCC0 register bits are set to all "1" The IOCD0 register bits are set to all "1" Bit 7 of the IOCE0 register is set to "1", and Bit 6~0 are cleared Bits 0~6 of RF register and bits 0~6 of IOCF register are cleared Executing the “SLEP” instruction will assert the sleep (power down) mode. While entering sleep mode, the Oscillator, TCC, TIMER1, TIMER2, and TIMER3 are stopped. The WDT (if enabled) is cleared but keeps on running. The controller can be awakened byCase 1 External reset input on /RESET pin Case 2 WDT time-out (if enabled) Case 3 Port 6 input status changes (if ICWE is enabled) Case 4 Comparator output status changes (if CMPWE is enabled) Case 5 AD conversion completed (if ADWE enable). Case 6 PWM/Timer is overflow (if PWMWE enable). The first two cases (1 & 2) will cause the PH86P558 to reset. The T and P flags of R3 can be used to determine the source of the reset (wake-up). Cases 3, 4, & 5 are considered the continuation of program execution and the global interrupt ("ENI" or "DISI" being executed) decides whether or not the controller branches to the interrupt vector following wake-up. If ENI is executed before SLEP, the instruction will begin to execute from address 0x8 after wake-up. If DISI is executed before SLEP, the execution will restart from the instruction next to SLEP after wake-up. All sleep mode wake up time is 2ms in high XTAL mode. In RC mode (IRC or ERC), wake up time is 10μs. Under low XTAL mode, wake up time is 500ms. Only one of the Cases 1 to 5 can be enabled before entering into sleep mode. That is: Product Specification (Draft 0.98) 04.03.2006 (This specification is subject to change without further notice) • 57 Contents Case [a] If WDT is enabled before SLEP, all of the RE bit is disabled. Hence, the PH86P558 can be awaken only with Case 1 or Case 2. Refer to the section on Interrupt (Section 6.7) for further details. Case [b] If Port 6 Input Status Change is used to wake -up PH86P558 and ICWE bit of RE register is enabled before SLEP, WDT must be disabled. Hence, the PH86P558 can be awaken only with Case 3. Wake-up time is dependent on oscillator mode. Under RC mode the reset time is 32 clocks (for oscillator stables). In High XTAL mode, reset time is 2ms and 32clocks(for oscillator stables); and in low XTAL mode, the reset time is 500ms. Case [c] If Comparator output status change is used to wake-up PH86P558 and CMPWE bit of RE register is enabled before SLEP, WDT must be disabled by software. Hence, the PH86P558 can be awaken only with Case 4. Wake-up time is dependent on oscillator mode. Under RC mode the reset time is 32 clocks (for oscillator stables). In High XTAL mode, reset time is 2ms and 32 clocks (for oscillator stables); and in low XTAL mode, the reset time is 500ms. Case [d] If AD conversion completed is used to wake-up PH86P558 and ADWE bit of RE register is enabled before SLEP, WDT must be disabled by software. Hence, the PH86P558 can be awaken only with Case 5. The wake-up time is 15 TAD (ADC clock period). Wake-up time is dependent on oscillator mode. Under RC mode the reset time is 32 clocks (for oscillator stables). In High XTAL mode, reset time is 2ms and 32 clocks (for oscillator stables); and in low XTAL mode, the reset time is 500ms. Case [e] If PWM/Timer output status change is used to wake-up PH86P558 and PWMWE bit of RE register is enabled before Idle mode(except sleep mode), WDT must be disabled by software. Hence, the PH86P558 can be awakening only with Case 6. Wake-up time is dependent on oscillator mode. Under RC mode the reset time is 32 clocks (for oscillator stables). In High XTAL mode, reset time is 2ms and 32 clocks (for oscillator stables); and in low XTAL mode, the reset time is 500ms.

TCC overflow interrupt 2. Port 6 Input Status Change Interrupt 3. External interrupt [(P52, /INT0), (P53,/INT1) pin] 4. Analog to Digital conversion completed 5. When TMR1/TMR2 matches with PRD1/PRD2/PRD3 respectively in PWM 6. When the comparators output changes 7.Completion of Serial interface transmit/ receive Before the Port 6 Input Status Change Interrupt is enabled, reading Port 6 (e.g., "MOV R6, R6") is necessary. Each Port 6 pin will have this feature if its status changes. Any pin configured as output, including the P52 (/INT0), and P53 (/INT1), is excluded from this function. Port 6 Input Status Change Interrupt will wake up the PH86P558 from sleep mode if it is enabled prior to going into the sleep mode by executing SLEP. When wake-up occurs, the controller will continue to execute the succeeding program if the global interrupt is disabled. If enabled, it will branch out to the interrupt vector 008H. External interrupt equipped with digital noise rejection circuit (input pulse less than 8 system clocks time) is eliminated as noise. Edge selection is possible with /INT. Refer to the Word 1 Bits 8~7 (Section 6.14.2, Code Option Register (Word 1)) for digital noise rejection definition. RF is the interrupt status register that records the interrupt requests in the relative flags/bits. IOCF is an interrupt mask register. The global interrupt is enabled by the ENI instruction and is disabled by the DISI instruction. When one of the interrupts (when enabled) occurs, the next instruction will be fetched from address 008H. Once in the interrupt service routine, the source of an interrupt can be determined by polling the flag bits in RF. The interrupt flag bit must be cleared by instructions before leaving the interrupt service routine to avoid recursive interrupts. The flag (except ICIF bit) in the Interrupt Status Register (RF) is set regardless of the status of its mask bit or of the ENI execution. Note that the result of RF will be the logic AND of RF and IOCF (refer to figure below). The RETI instruction ends the interrupt routine and enables the global interrupt (the ENI execution).

The analog reference voltage (Vref) and the analog ground are connected via separate input pins. The ADC module utilizes successive approximation to convert the unknown analog signal into a digital value. The result is fed to the ADDATA, ADDATA1H and ADDATA1L. Input channels are selected by the analog input multiplexer via the ADCON register Bits.

Product Specification (Draft 0.98) 04.03.2006 (This specification is subject to change without further notice) • 73 Contents 6.9.3 ADC Sampling Time The accuracy, linearity, and speed of the successive approximation of AD converter are dependent on the properties of the ADC and the comparator. The source impedance and the internal sampling impedance directly affect the time required to charge the sample holding capacitor. The application program controls the length of the sample time to meet the specified accuracy. Generally speaking, the program should wait for 2μs for each KΩ of the analog source impedance and at least 2μs for the low-impedance source. The maximum recommended impedance for analog source is 10KΩ at Vdd=5V. After the analog input channel is selected, this acquisition time must be done before the conversion is started. 6.9.4 AD Conversion Time CKR1 and CKR0 select the conversion time (Tct), in terms of instruction cycles. This allows the MCU to run at the maximum frequency without sacrificing the AD conversion accuracy. For the PH86P558, the conversion time per bit is about 4μs. The table below shows the relationship between Tct and the maximum operating frequencies. CKR1:CKR0 Operation Mode Max. Operation Max. Conversion Frequency Rate/Bit Max. Conversion Rate 00 Fosc/16 4MHz 250KHz (4us) 15*4us=60us(16.7KHz) 01 Fosc/4 1MHz 250KHz (4us) 15*4us=60us(16.7KHz) 10 Fosc/64 16MHz 250KHz( 4us) 15*4us=60us(16.7KHz) 11 Internal RC - 14KHz (71us) 15*71us=1065us(0.938KHz) NOTE ■ Pin not used as an analog input pin can be used as regular input or output pin. ■ During conversion, do not perform output instruction to maintain precision for all of the pins. 6.9.5 ADC Operation during Sleep Mode In order to obtain a more accurate ADC value and reduce power consumption, the AD conversion remains operational during sleep mode. As the SLEP instruction is executed, all the MCU operations will stop except for the Oscillator, TCC, TIMER1, TIMER2, TIMER3, Timer4 and AD conversion. The AD Conversion is considered completed as determined by: 1. ADRUN bit of R9 register is cleared (“0” value) 2. Wake-up from AD conversion (where it remains in operation during sleep mode) The results are fed into the ADDATA, ADDATA1H, and ADDATA1L registers when the conversion is completed. If the ADWE is enabled, the device will wake up. Otherwise, the AD conversion will be shut off, no matter what the status of ADPD bit is. 6.9.6 Programming Process/Considerations 6.9.6.1 Programming Process Follow these steps to obtain data from the ADC: 74 • Product Specification (V0.98) 04.03.2006 Contents 1.

Write to the Bank2 R9/ADCON register to configure AD module: a) Select ADC input channel ( ADIS2:ADIS0 ) b) Define AD conversion clock rate ( CKR1:CKR0 ) c) Select the VREFS input source of the ADC d) Set the ADPD bit to 1 to begin sampling 3. Set the ADWE bit, if the wake-up function is employed 4. Set the ADIE bit, if the interrupt function is employed 5. Write “ENI” instruction, if the interrupt function is employed 6. Set the ADRUN bit to 1 7. Write “SLEP” instruction or Polling. 8. Wait for wake-up or for ADRUN bit to be cleared (“0” value) 9. Read the ADDATA or ADDATA1H and ADDATA1L conversion data registers. If ADC input channel changes at this time, the ADDATA, ADDATA1H, and ADDATA1L values can be cleared to ‘0’. 10. Clear the interrupt flag bit (ADIF). 11.

A PWM output consisted of a time period and a duty cycle, and it keeps the output high. The baud rate of the PWM is the inverse of the time period.

They are designed for the PWM module as baud rate clock generators. TMRX can be read only. If employed, they can be turned off for power saving by setting the T1EN bit [Bank1 R5<3>], T2EN bit [Bank1 R6<7>]. or T3EN bit [Bank1 R6<3>] to 0. 6.10.3 PWM Time Period (PRDX : PRD1 or PRD2) The PWM time period is defined by writing to the PRDX register.

When DLX is equal to TMRX, the PWMX pin is cleared. DTX can be loaded anytime. However, it cannot be latched into DLX until the current value of DLX is equal to TMRX.

They are designed for the PWM module as baud rate clock generators. TMRX can be read only. The TIMER1, TIMER2, and TIMER3 will stop running when sleep mode occurs with AD conversion not running. However, if AD conversion is running when sleep mode occurs, the TIMER1, TIMER2 and TIMER3, will keep on running.

In this case, the Schmitt trigger can be disabled for power saving by setting Bit 1, Bit 0<COS1, COS0> of the IOCA0 register to <1,1>. See Section 6.2.6, IOCA0 (CMPCON: Comparator Control Register) for Comparator/OP select bits function description. 6.12.4 Comparator Interrupt CMPIE (IOCE.0) must be enabled for the “ENI” instruction to take effect Interrupt is triggered whenever a change occurs on the comparator output pin The actual change on the pin can be determined by reading the Bit CMPOUT, IOCA0<2> CMPIF (RE.0), the comparator interrupt flag, can only be cleared by software 6.12.5 Wake-up from SLEEP Mode If enabled, the comparator remains active and the interrupt remains functional, even under SLEEP mode. If a mismatch occurs, the interrupt will wake up the device from SLEEP mode. The power consumption should be taken into consideration for the benefit of energy conservation. If the function is unemployed during SLEEP mode, turn off comparator before entering into sleep mode. 6.13 Oscillator 6.13.1 Oscillator Modes The PH86P558 can be operated in four different oscillator modes, such as High XTAL oscillator mode (HXT), Low XTAL oscillator mode (LXT), External RC oscillator mode (ERC), and RC oscillator mode with Internal RC oscillator mode (IRC). You can select one of them by programming the OSC2, OCS1, and OSC0 in the CODE Option register. Product Specification (Draft 0.98) 04.03.2006 (This specification is subject to change without further notice) • 83 Contents The Oscillator modes defined by OSC2, OCS1, and OSC0 are described below. Oscillator Modes OSC2 OSC1 OSC0 1 0 0 0 1 0 0 1 0 1 0 ERC (External RC oscillator mode); P50/OSCO acts as P50 ERC (External RC oscillator mode); P50/OSCO acts as OSCO 2 IRC (Internal RC oscillator mode); P50/OSCO acts as P50 2 0 1 1 3 1 1 0 1 1 1 IRC (Internal RC oscillator mode); P50/OSCO acts as OSCO LXT (Low XTAL oscillator mode) 3 HXT High XTAL oscillator mode) (default) 1 Under ERC mode, OSCI is used as oscillator pin. OSCO/P50 is defined by code option WORD0 Bit6 ~ Bit4. 2 Under IRC mode, P55 is normal I/O pin. OSCO/P50 is defined by code option WORD0 Bit6 ~ Bit4. 3 Under LXT and HXT modes; OSCI and OSCO are used as oscillator pins. These pins cannot and should not be defined as normal I/O pins. NOTE The transient point of the system frequency between HXT and LXY is around 400kHz. The maximum operating frequency limit of crystal/resonator at different VDDs, are as follows: Conditions Two clocks VDD Max. Freq.

Fig. 6.15 External Clock Input Circuit 84 • Product Specification (V0.98) 04.03.2006 Contents In the most applications, Pin OSCI and Pin OSCO can be connected with a crystal or ceramic resonator to generate oscillation. Fig. 6-16 below depicts such circuit. The same applies to the HXT mode and the LXT mode. Fig. 6-16 Crystal/Resonator Circuit The following table provides the recommended values for C1 and C2. Since each resonator has its own attribute, you should refer to the resonator specifications for appropriate values of C1 and C2. RS, a serial resistor, may be required for AT strip cut crystal or low frequency mode.

Nevertheless, it should be noted that the frequency of the RC oscillator is influenced by the supply voltage, the values of the resistor (Rext), the capacitor (Cext), and even by the operation temperature. Moreover, the frequency also changes slightly from one chip to another due to the manufacturing process variation. Product Specification (Draft 0.98) 04.03.2006 (This specification is subject to change without further notice) Fig. 6-17 External RC Oscillator Mode Circuit • 85 Contents In order to maintain a stable system frequency, the values of the Cext should be no less than 20pF, and that the value of Rext should be no greater than 1MΩ. If the frequency cannot be kept within this range, the frequency can be affected easily by noise, humidity, and leakage. The smaller the Rext in the RC oscillator is, the faster its frequency will be. On the contrary, for very low Rext values, for instance, 1 KΩ, the oscillator will become unstable because the NMOS cannot discharge the capacitance current correctly. Based on the above reasons, it must be kept in mind that all supply voltage, the operation temperature, the components of the RC oscillator, the package types, and the way the PCB is layout, have certain effect on the system frequency.

Internal RC oscillator mode has other frequencies (1MHz, 8MHz, and 455KHz) that can be set by CODE OPTION (WORD1), RCM1, and RCM0. Table below describes the PH86P558 internal RC drift with the variation of voltage, temperature, and process. 86 • Product Specification (V0.98) 04.03.2006 Contents Internal RC Drift Rate (Ta=25℃, VDD=5V±5%, VSS=0V) Drift Rate Internal RC Frequency Temperature (-40℃~+85℃) Voltage (2.3V~5.5V) Process Total 4MHz ±10% ±5% ±4% ±19% 8MHz ±10% ±6% ±4% ±20% 1MHz ±10% ±5% ±4% ±19% 455MHz ±10% ±5% ±4% ±19% Theoretical values are for reference only. Actual values may vary depending on actual process. 6.14 Power-on Considerations Any microcontroller is not warranted to start operating properly before the power supply stabilizes in steady state. PH86P558 is equipped with Power On Voltage Detector (POVD) with detection level range of 1.9V to 2.1V. The circuitry eliminates the extra external reset circuit. It will work well if Vdd rises quickly enough (50 ms or less). However, under critical applications, extra devices are still required to assist in solving power-on problems. 6.14.1 External Power-on Reset Circuit The circuit shown in the following figure implements an external RC to produce a reset pulse. The pulse width (time constant) should be kept long enough to allow Vdd to reach the minimum operating voltage. This circuit is used when the power supply has a slow Fig. 6-18 External Power on Reset Circuit power rise time. Because the current leakage from the /RESET pin is about ±5μA, it is recommended that R should not be great than 40 K. This way, the voltage at Pin /RESET is held below 0.2V. The diode (D) acts as a short circuit at power-down. The “C” capacitor is discharged rapidly and fully. Rin, the current-limited resistor, prevents high current discharge or ESD (electrostatic discharge) from flowing into Pin /RESET.

The residual voltage may trips below Vdd minimum, but not to zero. This condition may cause a poor power on reset.

The following steps are needed to setup the LVD function: Set the LVDEN of Register RE of bank2 to”1”, then use bit 1,0(LVD1,LVD0) of Register RE of bank2 to set LVD interrupt level Waiting for occur interrupt. The internal LVD module is using internal circuit to fit. When you set the LVDEN enable the LVD module. The current consumption will increase about 10uA. During the sleep mode, the LVD module continues to operate. If the device voltage drop slowly and crosses the detect point. The LVDIF bit will be set and device won’t wake up from sleep time. Until the others wake-up source of PH86P558, the LVD interrupt flag still set as the prior status. When system reset, the LVD flag will be clear. When Vdd drop not below VLVD, LVDIF keep at “0”. When Vdd drop below VLVD, LVDIF set to “1”. If global ENI enable, LVDIF will be set to “1”, the next instruction will branched to interrupt vector. The LVD interrupt flag clear to “0” by software. When Vdd drop below VRESET and less than 80us, system will keep all the register status and system halt but oscillation active.

Normally, all instructions are executed within one single instruction cycle (one instruction consists of 2 oscillator time periods), unless the program counter is changed by instructions "MOV R2,A," "ADD R2,A," or by instructions of arithmetic or logic operation on R2 (e.g., "SUB R2,A," "BS(C) R2,6," "CLR R2," etc.). In this case, these instructions need one or two instruction cycles as determined by Code Option Register CYES bit. In addition, the instruction set has the following features: 1. Every bit of any register can be set, cleared, or tested directly. 2. The I/O registers can be regarded as general registers. That is, the same instruction can operate on I/O registers. The symbol "R" represents a register designator that specifies which one of the registers (including operational registers and general-purpose registers) is to be utilized by the instruction. The symbol "b" represents a bit field designator that selects the value for the bit located in the register "R" that is affected by the operation. The symbol "k" represents an 8 or 10-bit constant or literal value. 92 • Product Specification (V0.98) 04.03.2006 Contents The following are the list of the PH86P558 instruction set Instruction Binary 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0001 0001 0001 0001 0010 0010 0010 0010 0011 0011 0011 0011 0100 0100 0100 0100 0101 0101 0101 0101 0110 0110 0110 0110 0111 0111 0111 0111 100b 101b 110b 111b 00kk 01kk 1000 1001 0000 0000 0000 0001 0000 0010 0000 0011 0000 0100 0000 rrrr 0001 0000 0001 0001 0001 0010 0001 0011 0001 0100 0001 rrrr 01rr rrrr 1000 0000 11rr rrrr 00rr rrrr 01rr rrrr 10rr rrrr 11rr rrrr 00rr rrrr 01rr rrrr 10rr rrrr 11rr rrrr 00rr rrrr 01rr rrrr 10rr rrrr 11rr rrrr 00rr rrrr 01rr rrrr 10rr rrrr 11rr rrrr 00rr rrrr 01rr rrrr 10rr rrrr 11rr rrrr 00rr rrrr 01rr rrrr 10rr rrrr 11rr rrrr 00rr rrrr 01rr rrrr 10rr rrrr 11rr rrrr bbrr rrrr bbrr rrrr bbrr rrrr bbrr rrrr kkkk kkkk kkkk kkkk kkkk kkkk kkkk kkkk HEX Mnemonic 0000 0001 0002 0003 0004 000r 0010 0011 0012 0013 0014 001r 00rr 0080 00rr 01rr 01rr 01rr 01rr 02rr 02rr 02rr 02rr 03rr 03rr 03rr 03rr 04rr 04rr 04rr 04rr 05rr 05rr 05rr 05rr 06rr 06rr 06rr 06rr 07rr 07rr 07rr 07rr 0xxx 0xxx 0xxx 0xxx 1kkk 1kkk 18kk 19kk NOP DAA CONTW SLEP WDTC IOW R ENI DISI RET RETI CONTR IOR R MOV R,A CLRA CLR R SUB A,R SUB R,A DECA R DEC R OR A,R OR R,A AND A,R AND R,A XOR A,R XOR R,A ADD A,R ADD R,A MOV A,R MOV R,R COMA R COM R INCA R INC R DJZA R DJZ R RRCA R RRC R RLCA R RLC R SWAPA R SWAP R JZA R JZ R BC R,b BS R,b JBC R,b JBS R,b CALL k JMP k MOV A,k OR A,k Operation No Operation Decimal Adjust A A → CONT 0 → WDT, Stop oscillator 0 → WDT A → IOCR Enable Interrupt Disable Interrupt [Top of Stack] → PC [Top of Stack] → PC, Enable Interrupt CONT → A IOCR → A A→R 0→A 0→R R-A → A R-A → R R-1 → A R-1 → R A ∨ VR → A A ∨ VR → R A&R→A A&R→R A⊕R→A A⊕R→R A+R→A A+R→R R→A R→R /R → A /R → R R+1 → A R+1 → R R-1 → A, skip if zero R-1 → R, skip if zero R(n) → A(n-1),R(0) → C, C → A(7) R(n) → R(n-1),R(0) → C, C → R(7) R(n) → A(n+1),R(7) → C, C → A(0) R(n) → R(n+1),R(7) → C, C → R(0) R(0-3) → A(4-7),R(4-7) → A(0-3) R(0-3) ↔ R(4-7) R+1 → A, skip if zero R+1 → R, skip if zero 0 → R(b) 1 → R(b) if R(b)=0, skip if R(b)=1, skip PC+1 → [SP],(Page, k) → PC (Page, k) → PC k→A A∨k→A Product Specification (Draft 0.98) 04.03.2006 (This specification is subject to change without further notice) Status Affected None C None T,P T,P 1 None None None None None None 1 None None Z Z Z,C,DC Z,C,DC Z Z Z Z Z Z Z Z Z,C,DC Z,C,DC Z Z Z Z Z Z None None C C C C None None None None 2 None 3 None None None None None None Z • 93 Contents Instruction Binary 1 1 1 1 1 1 1 94 • 1010 1011 1100 1101 1110 1110 1111 kkkk kkkk kkkk kkkk 1000 1001 kkkk kkkk kkkk kkkk kkkk 00kk 00kk kkkk HEX 1Akk 1Bkk 1Ckk 1Dkk 1E8K 1E9K 1Fkk Mnemonic Operation Status Affected AND A,k A&k→A Z XOR A,k A⊕k→A Z RETL k k → A,[Top of Stack] → PC None SUB A,k k-A → A Z,C,DC PAGE k k->R3(7:5) None BANK k k->R4(7:6) None ADD A,k k+A → A Z,C,DC 1 This instruction is applicable to IOC50 ~ IOCF, IOC51 ~ IOCF1 only. 2 This instruction is not recommended for RF operation. 3 This instruction cannot operate under RF.
