When the jump or subroutine call instructions or the interrupt or initial reset conditions are to be executed, the address corresponding to the instruction will be loaded into the program counter. The format used is shownStack Register (STACK)The stack register is organized as 11 bits × 8 levels (first-in, last-out). When either a call subroutine or an interrupt is executed, the program counter will be pushed onto the stack register automatically. At the end of a call subroutine or an interrupt service subroutine, the RTN instruction must be executed to pop the contents of the stack register into the program counter. When the stack register is pushed over the eighth level, the contents of the first level will be lost. In other words, the stack register is always eight levels deep.Program Memory (flash EEPROM)The flash EEPROM is used to store program codes; the look-up table is arranged as 2048 × 4 bits. The first three quarters of flash EEPROM (000H to 5FFH) are used to store instruction codes only, but the last quarter (600H to 7FFH) can store both instruction codes and the look-up table. Each look-up table element is composed of 4 bits, so the look-up table can be addressed up to 2048 elements. There are two registers (TABL and TABH) to be used in look-up table addressing and they are controlled by MOV TABH, R and MOV TABL, R instructions. When the instruction MOVC R is executed, the contents of the look-up table location address specified by TABH, TABL and ACC will be read and transferred to the data RAM. Refer to the instruction table for more details. The organization of the program memory is shown in Figure 1.Publication Release Date: March 1998Figure 1. Program Memory OrganizationData Memory (RAM)1. ArchitectureThe static data memory (RAM) used to store data is arranged as 128 × 4 bits. The data memory can be addressed directly or indirectly. The organization of the data memory is shown in Figure 2.Figure 2. Data Memory OrganizationThe first sixteen addresses (00H to 0FH) in the data memory are known as the working registers (WR). The other data memory is used as general memory and cannot operate directly with immediate data. The relationship between data memory locations and the page register (PAGE) in indirect addressing mode is described in the next section.2. Page Register (PAGE)The page register is organized as a 4-bit binary register. The bit descriptions are as follows:PAGENote: R/W means read/write available.Bit 3 is reserved.Bit 2, Bit 1, Bit 0 Indirect addressing mode preselect bits:000 = Page 0 (00H - 0FH)001 = Page 1 (10H - 1FH)010 = Page 2 (20H - 2FH)011 = Page 3 (30H - 3FH)100 = Page 4 (40H - 4FH)101 = Page 5 (50H - 5FH)110 = Page 6 (60H - 6FH)111 = Page 7 (70H - 7FH)Accumulator (ACC)The accumulator (ACC) is a 4-bit register used to hold results from the ALU and transfer data between the memory, I/O ports, and registers.Arithmetic and Logic Unit (ALU)This is a circuit which performs arithmetic and logic operations. The ALU provides the following functions:•Logic operations: ANL, XRL, ORL•Branch decisions: JB0, JB1, JB2, JB3, JNZ, JZ, JC, JNC, DSKZ, DSKNZ, SKB0, SKB1, SKB2, SKB3 •Shift operations: SHRC, RRC, SHLC, RLC•Binary additions/subtractions: ADC, SBC, ADD, SUB, ADU, DEC, INCAfter any of the above instructions are executed, the status of the carry flag (CF) and zero flag (ZF) is stored in the internal registers. CF can be read out by executing MOVA R, CF.Publication Release Date: March 1998 Clock GeneratorThe W741E20X provides a crystal or RC oscillation circuit selected by option codes to generate the system clock through external connections. If a crystal oscillator is used, a crystal or a ceramic resonator must be connected to XIN and XOUT, and the capacitor must be connected if an accurate frequency is needed. When a crystal oscillator is used, a high-frequency clock (400 KHz to 4 MHz) or low-frequency clock (32 KHz) can be selected for the system clock by means of option codes. If the RC oscillator is used, a resistor in the range of 20 K Ω to 1.6 M Ω must be connected to XIN and XOUT, as shown in Figure 3. The system clock frequency range is from 32 KHz to 4 MHz. One machine cycle consists of a four-phase system clock sequence and can run up to 1 µS with a 4 MHz system clock.Figure 3. Oscillator ConfigurationDivider 0Divider 0 is organized as a 14-bit binary up-counter designed to generate periodic interrupts, as shown in Figure 4. When the system starts, the divider is incremented by each system clock (Fosc). When an overflow occurs, the divider event flag is set to 1 (EVF.0 = 1). Then, if the divider interrupt enable flag has been set (IEF.0 = 1), the interrupt is executed, while if the hold release enable flag has been set (HEF.0 = 1), the hold state is terminated. The last 4-stage of the Divider 0 can be reset by executing CLR DIVR0 instruction. If the oscillator is connected to the 32768 Hz crystal, the EVF.0 will be set to 1 periodically at each 500 mS interval.Watchdog Timer (WDT)The watchdog timer (WDT) is organized as a 4-bit up counter and is designed to protect the program from unknown errors. The WDT is enable when the corresponding option code bit of the WDT is set to 1. If the WDT overflows, the chip will be reset. At initial reset, the input clock of the WDT is F OSC /1024. The input clock of the WDT can be switched to F OSC /16384 (or F OSC /1024) by executing the SET PMF, #08H (or CLR PMF, #08H) instruction. The contents of the WDT can be reset by the instruction CLR WDT. In normal operation, the application program must reset WDT before it overflows. A WDT overflow indicates that the operation is not under control and the chip will be reset. The WDT minimun overflow period is 468.75 mS when the system clock (F OSC ) is 32 KHz and WDT clock input is F OSC /1024. When the corresponding option code bit of the WDT is set to 0, the WDT function is disabled. The organization of the Divider0 and watchdog timer is shown in Figure 4.Figure 4. Organization of Divider and Watchdog TimerParameter Flag (PMF)The parameter flag is organized as a 4-bit binary register (PMF.0 to PMF.3). The PMF is controlled by the SET PMF, #I or CLR PMF, #I instruction. The bit descriptions are as follows:123PMFNote: W means write only.Bit 0, Bit 1 & Bit 2 are reserved.Bit 3 = 0 The fundamental frequency of the watch dog timer is Fosc/1024.= 1 The fundamental frequency of the watch dog timer is Fosc/16384.At initial reset, bit 3 of PMF is set to "0".Publication Release Date: March 1998 Timer/CounterTimer 0 (TM0)Timer 0 (TM0) is a programmable 8-bit binary down-counter. The specified value can be loaded into TM0 by executing the MOV TM0L(TM0H), R or MOV TM0, #I instruction. When the MOV TM0L (TM0H), R instructions are executed, the TM0 will stop down-counting (if the TM0 is down-counting), the MR0.3 will be reset to 0, and the specified value is loaded into TM0. If MR0.3 is set to 1, the event flag 1 (EVF.1) is reset and the TM0 starts to count. When it decrements to FFH, Timer 0 stops operating and generates an underflow (EVF.1 = 1). The interrupt is executed if the Timer 0 interrupt enable flag has been set (IEF.1 = 1); and the hold state is terminated if the hold release enable flag 1 has been set (HEF.1 = 1). The Timer 0 clock input can be set as F OSC /1024 or F OSC /4 by setting MR0.0 to 1 or by resetting MR0.0 to 0. The default timer value is F OSC /4. The organization of Timer 0 is shown in Figure 5.If the Timer 0 clock input is Fosc/4, then: Desired time 0 interval = (preset value +1) × 4 × 1/Fosc If the Timer 0 clock input is Fosc/1024, then:Desired time 0 interval = (preset value +1) × 1024 × 1/Fosc Preset value: Decimal number of Timer 0 preset value Fosc: Clock oscillation frequencyFigure 5. Organization of Timer 0Timer 1 (TM1)Timer 1 (TM1) is also a programmable 8-bit binary down counter, as shown in Figure 6. Timer 1 can input clock of Timer 1 can be one of three sources: Fosc/64, Fosc, or an external clock from the RC.0input pin. The source can be selected by setting bit 0 and bit 1 of mode register 1 (MR1). At initial reset, the Timer 1 clock input is Fosc. If an external clock is selected as the clock source of Timer 1, the content of Timer 1 is decreased by 1 at the falling edge of RC.0. When the MOV TM1L, R or MOV TM1H,R instruction is executed, the specified data are loaded into the auto-reload buffer and the TM1 down-counting will be disabled (i.e. MR1.3 is reset to 0). If the bit 3 of MR1 is set (MR1.3 = 1), the contents of the auto-reload buffer will be loaded into the TM1 down counter, Timer 1 starts to down count, and the event flag 7 is reset (EVF.7 = 0). When the MOV TM1, #I instruction is executed, the event flag 7 (EVF.7) and MR1.3 are reset and the specified value is loaded into auto-reload buffer and TM1 by the internal hardware, then the MR1.3 is set, that is the TM1 starts to count by the hardware. When the timer decrements to FFH, it will generate an underflow (EVF.7 = 1) and be auto-reloaded with the specified data, after which it will continue to count down. An interrupt is executed if the interrupt enable flag 7 has been set to 1 (IEF.7 = 1), and the hold state is terminated if the hold mode release enable flag 7 is set to 1 (HEF.7 = 1). The specified frequency of Timer 1 can be delivered to the MFP output pin by programming bit 2 of MR1. Bit 3 of MR1 can be used to make Timer 1 stop or start counting.If the Timer 1 clock input is F T, then :Desired Timer 1 interval = (preset value +1) / F TDesired frequency for MFP output pin = F T ÷ (preset value + 1) ÷ 2 (Hz) Preset value: Decimal number of Timer 1 preset value, and Fosc: Clock oscillation frequencyFigure 6. Organization of Timer 1Publication Release Date: March 1998 For example, when F T equals 32768 Hz, depending on the preset value of TM1, the MFP pin will output a single tone signal in the tone frequency range from 64 Hz to 16384 Hz.

Input/Output Ports RC, RDPort RC consists of pins RC.0 to RC.3, and port RD consists of pins RD.0 to RD.3. At initial reset, input/output ports RC and RD are both in input mode. When RC and RD are used as output ports, the CMOS type is the only ouput driving type. Each pin of port RC or RD can be specified as input or output mode independently by the PM4 and PM5 registers. The MOVA R, RC or MOVA R, RD instructions operate the input functions and the MOV RC, R or MOV RD, R operate the output functions. When the PEF, HEF, and IEF corresponding to the RC port are set, a signal change at the specified pins of port RC will execute the hold mode release or interrupt subroutine. Port status register 0 (PSR0) records the status of port RC, and that can be read out and cleared by the MOV R, PSR0, and CLR PSR0 instructions. Before the port mode of the RC port is changed from output mode to input mode in the hold mode release and interrupt application, the output value must be preset to the same as the system status to prevent the undesired signal change being accepted. When the interrupt of RC port is accepted, the corresponding event flag (EVF.2) will be reset, but the content of PSR0 should not be changed except the CLR PSR0 or MOV PEF,#I instruction being executed or performing the reset function. In addition, the falling edge signal on the pin of port RC specified by the instruction MOV SEF, #I will cause the device to exit the stop mode. The RD port is used as the I/O port only. Refer to Figure 9, Figure 10 and the instruction table for more details.Figure 9. Architecture of RC & RD Input/Output PinsPort Enable Flag (PEF)The port enable flag is organized as 4-bit binary register (PEF.0 to PEF.3). Before port RC may be used to release the hold mode or preform interrupt function, the content of the PEF must be set first. The PEF is controlled by the MOV PEF, #I instruction. The bit descriptions are as follows:PEF 0123Note: W means write only.PEF.0: Enable/disable the signal change at pin RC.0 to release hold mode or perform interrupt. PEF.1: Enable/disable the signal change at pin RC.1 to release hold mode or perform interrupt. PEF.2: Enable/disable the signal change at pin RC.2 to release hold mode or perform interrupt. PEF.3: Enable/disable the signal change at pin RC.3 to release hold mode or perform interrupt.Port Status Register 0 (PSR0)Port status register 0 is organized as 4-bit binary register (PSR0.0 to PSR0.3). PSR0 can be read orcleared by the MOVA R, PSR0, and CLR PSR0 instructions. The bit descriptions are as follows:0123PSR0Note: R means read only.Publication Release Date: March 1998 Bit 0 = 1 Signal change at RC.0 Bit 1 = 1 Signal change at RC.1 Bit 2 = 1 Signal change at RC.2 Bit 3 = 1 Signal change at RC.3Figure 10. Input Architecture of Ports RCOutput Port REOutput port RE can be used as an output of the internal RT port, or as a serial input/output port. The control flow is shown in Figure 8. When bit 1 of port mode 3 register (PM3) equals to 0, port RE works as an output of internal port RT. When the MOV RE, R instruction is executed, the data in the RAM will be output to port RT through port RE. When RE works as a parallel output port, it provides a high sink current to drive LEDs. When bit 1 of MR0 equals to 1, the RE port works as a serial input/output port, and RE.0 to RE.3 are used as DOUT, CLKO, DIN, and CLKI, respectively. In this case, the DIN pin will has a built-in pull-high resistor. The serial I/O functions are controlled by the instructions SOP R and SIP R. The functions of the two instructions are described below:(1) When the SIP R instruction is executed, the data will be loaded from the serial input buffer to the ACC and RAM first, and bit 1 of port status register 2 will automatically be set to "1" (BUSYI = 1). Then the CLKI pin will send out 8 clocks and the data from the DIN pin will be loaded to SIB at the rising edge of the CLKI pin. After the 8 clocks have been sent, BUSYI will be reset to "0" and EVF.5 will be set to "1." At this time, if IEF.5 has been set (IEF.5 = 1), an interrupt is executed; if HEF.5 has been set (HEF.5 = 1), the hold state is terminated. Users can check the status of PSR2.1 (BUSYI) to know whether the serial input process is completed or not. If a serial input process is not completed, and the SIP R instruction is executed again, the data will be lost. The timing is shown in Figure 11.Figure 11. Timing of the Serial Input Function (SIP R)Publication Release Date: March 1998 (2) When the SOP R instruction is executed, the data will be loaded to the serial output buffer (SOB) and bit 3 of port status register 2 will be set to "1" (BUSYO = 1). Then the CLKO pin will send out 8 clocks and the data in SOB will be sent out at the falling edge of the CLKO pin. After the 8 clocks have been sent, BUSYO will be reset to "0" and EVF.6 will be set to "1." At this time, if IEF.6 has been set (IEF.6 = 1), an interrupt is executed; if HEF.6 has been set (HEF.6 = 1), the hold state is terminated. Users can check the status of PSR2.3 (BUSYO) to know whether the serial output process is completed or not. If a serial output process is not completed, and the SOP R instructionFigure 12. Timing of the Serial Output Function (SOP R)In the above description, the low nibble location of the serial input/output register is contributed to the ACC, and the high nibble is to R. The port status register 2 (PSR2) including BUSYI, and BUSYO can be read out or cleared by the MOVA R, PSR2, or CLR PSR2 instruction.Port Status Register 2 (PSR2)Port status register 2 is organized as 4-bit binary register (PSR2.0 to PSR2.3). PSR2 is controlled by the MOVA R, PSR2, and CLR PSR2 instructions. The bit descriptions are as follows:123PSR2Note: R means read only.Bit 0 is reserved.Bit 1 (BUSYI):Serial port input busy flag.Bit 2 is reserved.Bit 3 (BUSYO):Serial port output busy flag.MFP Output Pin (MFP)The MFP output pin can output the Timer 1 clock or the modulation frequency; the output of the pin is determined by mode register 1 (MR1). The organization of MR1 is shown in Figure 6. When bit 2 of MR1 is reset to "0," the MFP output can deliver a modulation output in any combination of one signal from among DC, 4096Hz, 2048Hz, and one or more signals from among 128 Hz, 64 Hz, 8 Hz, 4 Hz, 2 Hz, or 1 Hz (when using a 32.768 KHz crystal). The MOV MFP, #I instruction is used to specify the modulation output combination. The data specified by the 8-bit operand and the MFP output pin are shown as below.(Fosc = 32.768 KHz)R6 R5 R4 R3 R2 R1 R0 FUNCTION R7levelLow0 0 0 0 0 0Hz1280 0 0 0 0 1Hz640 0 0 0 1 0Hz80 0 0 0 1 0 04Hz0 0 1 0 0 00 1 0 0 0 0 2 HzHz1 0 0 0 0 01level0 0 0 0 0 0HighHz1280 0 0 0 0 1Hz0 0 0 0 1 0648Hz1 0 0 0 1 0 0Hz0 0 1 0 0 04Hz20 1 0 0 0 0Hz11 0 0 0 0 0Hz0 0 0 0 0 020480 0 0 0 0 1 2048 Hz * 128 Hz64Hz*0 0 0 0 1 02048Hz1 0 0 0 0 1 0 0 2048 Hz * 8 Hz4Hz*Hz20480 0 1 0 0 02Hz*0 1 0 0 0 0Hz20481Hz*20481 0 0 0 0 0Hz。
