Functional Description
Execution Flow The system clock for the HT86R192 series is derived from either a crystal or an RC oscillator. It is internally divided into four non-overlapping clocks. One instruction cycle consists of four system clock cycles. Instruction fetching and execution are pipelined in such a way that a fetch takes one instruction cycle while decoding and execution takes the next instruction cycle. However, the pipelining scheme causes each instruction to effectively execute within one cycle. If an instruction changes the Program Counter, two cycles are required to complete the instruction.

Program Counter - PC The 13-bit Program Counter (PC) controls the sequence in which the instructions stored in program ROM are executed. After accessing a program memory word to fetch an instruction code, the contents of the Program Counter are incremented by one. The Program Counter then points to the memory word containing the next instruction code. When executing a jump instruction, conditional skip execution, loading PCL register, subroutine call, initial reset, internal interrupt, external interrupt or return from

subroutine, the PC manipulates the program transfer by loading the address corresponding to each instruction. The conditional skip is activated by instruction. Once the condition is met, the next instruction, fetched during the current instruction execution, is discarded and a dummy cycle takes its place while the correct instruction is obtained. The lower byte of the Program Counter (PCL) is a read/write register (06H). Moving data into the PCL performs a short jump. The destination must be within 256 locations. When a control transfer takes place, an additional dummy cycle is required. Program Memory - ROM The program memory stores the program instructions that are to be executed. It also includes data, table and interrupt entries, addressed by the Program Counter along with the table pointer. The program memory size for HT86R192 is 819216 bits. Certain locations in the program memory are reserved for special usage:
* Location 000H * Location 008H
HT86R192
This area is reserved for the 16-bit Timer/Event Counter 0 interrupt service program. If a timer interrupt results from a Timer/Event Counter 0 overflow, and if the interrupt is enabled and the stack is not full, the program will jump to location 008H and begins execution.
* Location 00CH
This area is reserved for the 16-bit Timer/Event Counter 1 interrupt service program. If a timer interrupt results from a Timer/Event Counter 1 overflow, and if the interrupt is enabled and the stack is not full, the program will jump to location 00CH and begins execution.
* Location 010H
This area is reserved for the 16-bit Timer Counter 2 interrupt service program. If a timer interrupt results from a Timer Counter 2 overflow, and if the interrupt is enabled and the stack is not full, the program will jump to location 010H and begins execution.
* Location 014H
This area is reserved for program initialization. The program always begins execution at location 000H each time the system is reset.
* Location 004H
This area is reserved for the 8-bit Timer Counter 3 interrupt service program. If a timer interrupt results from a Timer Counter 3 overflow, and if the interrupt is enabled and the stack is not full, the program will jump to location 014H and begins execution. Table Location Any location in the ROM space can be used as look up tables. The instructions TABRDC [m] (used for any bank) and TABRDL [m] (only used for last page of program ROM) transfer the contents of the lower-order byte to the specified data memory [m], and the higher-order byte to TBLH (08H). Only the destination of the lower-order byte in the table is well-defined. The higher-order bytes of the table word are transferred to the TBLH. The table higher-order byte register (TBLH) is read only. The table pointer (TBHP, TBLP) is a read/write register, which indicates the table location. Because TBHP is unknown after power-on reset, TBHP must be set specified.
This area is reserved for the external interrupt service program. If the INT input pin is activated, and the interrupt is enabled and the stack is not full, the program will jump to location 004H and begins execution.

Stack Register - Stack The stack register is a special part of the memory used to save the contents of the Program Counter. This stack is organized into eight levels. It is neither part of the data nor part of the program space, and cannot be read or written to. Its activated level is indexed by a stack pointer (SP) and cannot be read or written to. At a subroutine call or interrupt acknowledgment, the contents of the Program Counter are pushed onto the stack. The Program Counter is restored to its previous value from the stack at the end of subroutine or interrupt routine, which is signaled by return instruction (RET or RETI). After a chip resets, SP will point to the top of the stack. The interrupt request flag will be recorded but the acknowledgment will be inhibited when the stack is full and a non-masked interrupt takes place. After the stack pointer is decremented (by RET or RETI), the interrupt request will be serviced. This feature prevents stack overflow and allows programmers to use the structure more easily. In a similar case, if the stack is full and a CALL is subsequently executed, stack overflow occurs and the first entry is lost. Data Memory - RAM The data memory is designed with 2088 bits. The data memory is further divided into two functional groups, namely, special function registers (00H~2AH) and general purpose user data memory (30H~FFH). Although most of them can be read or be written to, some are read only.

Indirect Addressing Register Location 00H and 02H are indirect addressing registers that are not physically implemented. Any read/write operation of [00H] and [02H] accesses the RAM pointed to by MP0 (01H) and MP1 (03H), respectively. Reading location 00H or 02H indirectly returns the result 00H. While, writing it indirectly leads to no operation. The function of data movement between two indirect addressing registers is not supported. The memory pointer registers, MP0 and MP1, are both 8-bit registers used to access the RAM by combining the corresponding indirect addressing registers. Accumulator - ACC (05H) The accumulator (ACC) is related to the ALU operations. It is also mapped to location 05H of the RAM and is capable of operating with immediate data. The data movement between two data memory locations must pass through the ACC. Arithmetic and Logic Unit - ALU This circuit performs 8-bit arithmetic and logic operations and provides the following functions:
* Arithmetic operations (ADD, ADC, SUB, SBC, DAA) * Logic operations (AND, OR, XOR, CPL) * Rotation (RL, RR, RLC, RRC) * Increment and Decrement (INC, DEC) * Branch decision (SZ, SNZ, SIZ, SDZ etc)
HT86R192
Except the TO and PDF flags, bits in the status register can be altered by instructions similar to other registers. Data written into the status register does not alter the TO or PDF flags. Operations related to the status register, however, may yield different results from those intended. The TO and PDF flags can only be changed by a Watchdog Timer overflow, chip power-up, or clearing the Watchdog Timer and executing the HALT instruction. The Z, OV, AC, and C flags reflect the status of the latest operations. On entering the interrupt sequence or executing the subroutine call, the status register will not be automatically pushed onto the stack. If the contents of the status is important, and if the subroutine is likely to corrupt the status register, the programmer should take precautions and save it properly. Interrupts The HT86R192 provides an external interrupt, three 16-bit programmable timer interrupts, and an 8-bit programmable timer interrupt. The Interrupt Control registers (INTC:0BH, INTCH:1EH) contain the interrupt control bits to set to enable/disable and the interrupt request flags. Once an interrupt subroutine is serviced, all other interrupts will be blocked (by clearing the EMI bit). This scheme may prevent any further interrupt nesting. Other interrupt requests may happen during this interval but only the interrupt request flag is recorded. If a certain interrupt needs servicing within the service routine, the EMI bit and the corresponding INTC/INTCH bit may be set to allow interrupt nesting. If the stack is full, the interrupt request will not be acknowledged, even if the related interrupt is enabled, until the SP is decremented. If immediate service is desired, the stack must be prevented from becoming full. Function
Status Register - STATUS (0AH) This 8-bit STATUS register (0AH) consists of a zero flag (Z), carry flag (C), auxiliary carry flag (AC), overflow flag (OV), power down flag (PDF), watchdog time-out flag (TO). It also records the status information and controls the operation sequence. Bit No. 0 Label C
C is set if an operation results in a carry during an addition operation or if a borrow does not take place during a subtraction operation; otherwise C is cleared. C is also affected by a rotate through carry instruction. AC is set if an operation results in a carry out of the low nibbles in addition or no borrow from the high nibble into the low nibble in subtraction; otherwise AC is cleared. Z is set if the result of an arithmetic or logical operation is zero; otherwise Z is cleared. OV is set if an operation results in a carry into the highest-order bit but not a carry out of the highest-order bit, or vice versa; otherwise OV is cleared. PDF is cleared by system power-up or executing the CLR WDT instruction. PDF is set by executing the HALT instruction. TO is cleared by system power-up or executing the CLR WDT or HALT instruction. TO is set by a WDT time-out. Unused bit, read as 0 Status (0AH) Register

As an interrupt is serviced, a control transfer occurs by pushing the Program Counter onto the stack and then branching to subroutines at the specified location(s) in the program memory. Only the Program Counter is pushed onto the stack. The programmer must save the contents of the register or status register (STATUS) in advance if they are altered by an interrupt service program which corrupts the desired control sequence. External interrupt is triggered by a high-to-low/ low-to-high transition of INT pin which sets the related interrupt request flag (EIF:bit 4 of INTC). When the interrupt is enabled, and the stack is not full and the external interrupt is active, a subroutine call to location 04H will occur. The interrupt request flag (EIF) and EMI bits will be cleared to disable other interrupts. The internal Timer/Event Counter 0 interrupt is initialized by setting the Timer/Event Counter 0 interrupt request flag (T0F:bit 5 of INTC), caused by a Timer/Event Counter 0 overflow. When the interrupt is enabled, and the stack is not full and the T0F bit is set, a subroutine call to location 08H will occur. The related interrupt request flag (T0F) will be reset and the EMI bit cleared to disable further interrupts. The internal Timer/Event Counter 1 interrupt is initialized by setting the Timer/Event Counter 1 interrupt request flag (T1F:bit 6 of INTC), caused by a Timer/Event Counter 1 overflow. When the interrupt is enabled, and the stack is not full and the T1F bit is set, a subroutine call to location 0CH will occur. The related interrupt request flag (T1F) will be reset and the EMI bit cleared to disable further interrupts. The internal Timer Counter 2 interrupt is initialized by setting the Timer Counter 2 interrupt request flag (T2F:bit 0 of INTCH), caused by a Timer Counter 2 overflow. When the interrupt is enabled, and the stack is not full and the T2F bit is set, a subroutine call to location 10H will occur. The related interrupt request flag (T2F) will be reset and the EMI bit cleared to disable further interrupts. The internal Timer Counter 3 interrupt is initialized by setting the Timer Counter 3 interrupt request flag (T3F:bit 1 of INTCH), caused by a Timer Counter 3 overflow. When the interrupt is enabled, and the stack is not full and the T3F bit is set, a subroutine call to location
HT86R192
14H will occur. The related interrupt request flag (T3F) will be reset and the EMI bit cleared to disable further interrupts. During the execution of an interrupt subroutine, other interrupt acknowledges are held until the RETI instruction is executed or the EMI bit and the related interrupt control bit are set to 1 (of course, if the stack is not full). To return from the interrupt subroutine, the RET or RETI instruction may be invoked. RETI will set the EMI bit to enable an interrupt service, but RET will not. Interrupts occurring in the interval between the rising edges of two consecutive T2 pulses, will be serviced on the latter of the two T2 pulses, if the corresponding interrupts are enabled. In the case of simultaneous requests, the following table shows the priority that is applied. These can be masked by resetting the EMI bit. The Timer/Event Counter 0/1 interrupt request flag (T0F/T1F) which enables Timer/Event Counter 0/1 control bit (ET0I/ET1I), the Timer Counter 2/3 interrupt request flag (T2F/T3F) which enables Timer Counter 2/3 control bit (ET2I/ET3I), and external interrupt request flag (EIF) which enables external interrupt control bit (EEI) form the interrupt control register (INTC:0BH and INTCH:1EH). EMI, EEI, ET0I, ET1I, ET2I, and ET3I are used to control the enabling/disabling of interrupts. These bits prevent the requested interrupt begin serviced. Once the interrupt request flags (T0F, T1F, T2F, T3F, EIF) are set, they will remain in the INTC/INTCH register until the interrupts are serviced or cleared by a software instruction. It is recommended that application programs do not use CALL subroutines within an interrupt subroutine. Interrupts often occur in an unpredictable manner or need to be serviced immediately in some applications. If only one stack is left and the interrupt enable is not well controlled, once a CALL subroutine if used in the interrupt subroutine will corrupt the original control sequence.

HT86R192
The HT86R192 provides two types of oscillator circuit for the system clock, i.e., RC oscillator and crystal oscillator. No matter what type of oscillator, the signal is used for the system clock. The HALT mode stops the system oscillator and ignores external signal to conserve power. If the RC oscillator is used, an external resistor between OSC1 and VSS is required, and the range of the resistance should be from 155kW to 300kW. The system clock, divided by 4, is available on OSC2 with pull-high resistor, which can be used to synchronize external logic. The RC oscillator provides the most cost effective solution. However, the frequency of the oscillation may vary with VDD, temperature, and the chip itself due to process variations. It is therefore not suitable for timing sensitive operations where accurate oscillator frequency is desired. On the other hand, if the crystal oscillator is selected, a crystal across OSC1 and OSC2 is needed to provide the feedback and phase shift required for the oscillator, and no other external components are required. A resonator may be connected between OSC1 and OSC2 to replace
S y s te m C lo c k /4 M ask O p tio n S e le c t
the crystal and to get a frequency reference, but two external capacitors in OSC1 and OSC2 are required. There is another oscillator circuit designed for Timer3s clock source as the RTC time base which is determined by OTP option. If the OTP option determines that Timer3s clock source is from a 32kHz crystal, then a 32kHz crystal should be connected to XIN and XOUT.

System Oscillator Watchdog Timer - WDT The WDT clock source is implemented by a dedicated RC oscillator (WDT oscillator) or instruction clock (system clock divided by 4), decided by OTP options. This timer is designed to prevent a software malfunction or sequence jumping to an unknown location with unpredictable results. The Watchdog Timer can be disabled

by OTP option. If the Watchdog Timer is disabled, all the executions related to the WDT result in no operation. Once the internal WDT oscillator (RC oscillator with period 78ms normally) is selected, it is first divided by 256 (8-stages) to get the nominal time-out period of approximately 20 ms. This time-out period may vary with temperature, VDD and process variations. By invoking the WDT prescaler, longer time-out period can be realized. Writing data to WS2, WS1, WS0 (bit 2,1,0 of WDTS(09H)) can give different time-out period. If WS2, WS1, WS0 all equal to 1, the division ratio is up to 1:128, and the maximum time-out period is 2.6 seconds. If the device operates in a noisy environment, using the on-chip RC oscillator (WDT OSC) is strongly recommended, since the HALT will stop the system clock. The WDT overflow under normal operation will initialize a chip reset and set the status bit TO. Whereas in the HALT mode, the overflow will initialize a warm re set only the Program Counter and SP are reset to zero. To clear the contents of the WDT (including the WDT prescaler), three methods are adopted; external reset (external reset (a low level to RES), software instructions, or a HALT instruction. The software instruction is CLR WDT and execution of the CLR WDT instruction will clear the WDT.

flags, the reason for the chip reset can be determined. The PDF flag is cleared when the system powers-up or executes the CLR WDT instruction, and is set when the HALT instruction is executed. The TO flag is set if a WDT time-out occurs, and causes a wake-up that only resets the Program Counter and SP. The other maintain their original status. The port A wake-up and interrupt methods can be considered as a continuation of normal execution. Each bit in port A can be independently selected to wake-up the device by a OTP option. Awakening from an I/O port stimulus, the program will resume execution of the next instruction. If awakening from an interrupt, two sequences may happen. If the related interrupt is disabled or the interrupt is enabled by the stack is full, the program will resume execution at the next instruction. If the interrupt is enabled and the stack is not full, the regular interrupt response takes place. Once a wake-up event occurs, it takes 1024 system clock period to resume normal operation. In other words, a dummy cycle period will be inserted after a wake-up. If the wake-up results from an interrupt acknowledge, the actual interrupt subroutine will be delayed by one more cycle. If the wake-up results in next instruction execution, this will be executed immediately after a dummy period is finished. If an interrupt request flag is set to 1 before entering the HALT mode, the wake-up function of the related interrupt will be disabled. To minimize power consumption, all I/O pins should be carefully managed before entering the HALT status.
There are 3 ways in which a reset can occur:
* RES reset during normal operation * RES reset during HALT * WDT time-out reset during normal operation
WDTS (09H) Register Power Down - HALT The HALT mode is initialized by a HALT instruction and results in the following: The system oscillator will be turned off but the WDT oscillator keeps running (if the WDT oscillator is selected).
* The contents of the on chip RAM and registers remain
The WDT time-out during HALT is different from other chip reset conditions, since it can perform a warm re set that resets only the Program Counter and SP, leaving the other circuits in their original state. Some registers remain unchanged during any other reset conditions. Most registers are reset to their initial condition when the reset conditions are met. By examining the PDF flag and TO flag, the program can distinguish between different chip resets.

To guarantee that the system oscillator has started and stabilized, the SST (System Start-up Timer) provides an extra-delay of 1024 system clock pulses after a system power up or when awakening from a HALT state. When a system power up occurs, the SST delay is added during the reset period. But when the reset comes from the RES pin, the SST delay is disabled. Any wake-up from HALT will enable the SST delay. The function unit chip reset status are shown below. Program Counter Interrupt Prescaler WDT 000H Disable Clear Clear. After master reset, WDT begins counting

Reset Configuration Timer/Event Counter 0/1 There are four timer counters are implemented in the HT86R192. The Timer/Event Counter 0 and 1 contain 16-bit programmable count-up counters whose clock may come from an external source or the system clock divided by 4 (T1). Using the internal instruction clock (T1), there is only one reference time base. The external clock input allows the user to count external events, measure time intervals or pulse width, or to generate an accurate time base. There are three registers related to Timer/Event Counter 0; TMR0H (0CH), TMR0L (0DH), TMR0C (0EH). Writing to TMR0L only writes the data into a low byte buffer. Writing to TMR0H will write the data and the contents of the low byte buffer into the Timer/Event Counter 0 preload register (16-bit) simultaneously. The Timer/Event Counter 0 preload register is changed only by a write to TMR0H operation. Writing to TMR0L will keep the Timer/Event Counter 0 preload register unchanged. Reading TMR0H will also latch the TMR0L into the low byte buffer to avoid false timing problems. Reading the TMR0L only returns the value from the low byte buffer which may be a previously loaded value. In other words, the low byte of Timer/Event Counter 0 cannot be read directly. It must read the TMR0H first to ensure that the low byte contents of Timer/Event Counter 0 are latched into the buffer. There are three registers related to the Timer/Event Counter 1; TMR1H (0FH), TMR1L (10H), TMR1C (11H). The Timer/Event Counter 1 operates in the same manner as Timer/Event Counter 0.

The Timer/Event Counter 1 has the same options as the Timer/Event Counter 0 and is defined by TMR1C. The timer/event counter control registers define the operating mode, counting enable or disable and active edge. The TM0, TM1 bits define the operating mode. The event count mode is used to count external events, which implies that the clock source comes from an external (TMR0/TMR1 is connected to PC4/PC5) pin. The timer mode functions as a normal timer with the clock source coming from the instruction clock. The pulse width measurement mode can be used to count the high o r lo w lev e l d u r at i o n of a n ex t e r nal si g n a l (TMR0/TMR1). The counting method is based on the instruction clock. In the event count or timer mode, once the timer/event counter starts counting, it will count from the current contents in the timer/event counter to FFFFH. Once an overflow occurs, the counter is reloaded from the timer/event counter preload register and generates a corresponding interrupt request flag (T0F/T1F; bit 5/6 of INTC) at the same time. In the pulse width measurement mode with the TON and TE bits equal to one, once the TMR0/TMR1 has received a transient from low to high (or high to low; if the TE bit is 0) it will start counting until the TMR0/TMR1 returns to the original level and resets TON. The measured result will remain in the timer/event counter even if the activated transient occurs again. In other words, Rev. 0.00 18 Function Function

only one cycle measurement can be done. When TON is set again, the cycle measurement will function again as long as it receives further transient pulses. Note that, in this operating mode, the timer/event counter starts counting not according to the logic level but according to the transient edges. In the case of counter overflows, the counter is reloaded from the timer/event counter preload register and issues the interrupt request just like in the other two modes. To enable the counting operation, the Timer ON bit (TON; bit 4 of TMR0C/TMR1C) should be set to 1. In the pulse width measurement mode, TON will be cleared automatically after the measurement cycle is complete. But in the other two modes TON can only be reset by instruction. The overflow of the timer/event counter is one of the wake-up sources. No matter what the operation mode is, writing a 0 to ET0I/ET1I can disable the corresponding interrupt service. In the case of a Timer/Event Counter OFF condition, writing data to the timer/event counter preload register will also reload that data to the timer/event counter. But if the timer/event counter is turned on, data written to the timer/event counter will only be kept in the timer/event counter preload register. The timer/event counter will continue to operate until an overflow occurs. When the Timer/Event Counter (reading TMR0H/ TMR1H) is read, the clock will be blocked to avoid errors. As this may result in a counting error, this must be taken into consideration by the programmer.

Timer Counter 2 The timer counter TMR2 is also a 16-bit programmable count-up counter. It operates in the same manner as Timer/Event Counter 0/1, but the clock source of TMR2 is from only internal instruction cycle (T1). Therefore only (TM1,TM0)=(1,0) is allowable.

clock source of TMR3 can be from internal instruction cycle (T1) or external 32kHz crystal which is connected to XIN and XOUT. The TMR3s clock source is determined by OTP option. If the 32kHz crystal is enabled, then TMR3s clock source is 32kHz which is from XIN and XOUT. If the 32kHz crystal is disabled, then TMR3s clock source is internal T1. The TMR3 is internal clock source only, i.e. (TM1,TM0)=(1,0). There is a 3-bit prescaler (TMR3S2,TMR3S1,TMR3S0) which defines different division ratio of TMR3s clock source. Function

Preliminary
Input/Output Ports There are 23 bidirectional input/output lines in the microcontroller, labeled from PA to PC, which are mapped to the data memory of [12H], [14H], and [16H], respectively. All of these I/O ports can be used for input and output operations. For input operation, these ports are non-latching, that is, the inputs must be ready at the T2 rising edge of instruction MOV A, [m] (m=12H,14H or 16H). For output operation, all the data is latched and remains unchanged until the output latch is rewritten. Each I/O line has its own control register (PAC, PBC, PCC) to control the input/output configuration. With this control register, CMOS output or Schmitt trigger input with or without pull-high resistor structures can be reconfigured dynamically (i.e. on-the-fly) under software control. To function as an input, the corresponding latch of the control register must write 1. The input source also depends on the control register. If the control register bit is 1, the input will read the pad state. If the control register bit is 0, the contents of the latches will move to the internal bus. The latter is possible in the read-modify-write instruction. For output function, CMOS is the only configuration. These control registers are mapped to locations 13H, 15H, and 17H. Bit 7 which is mapped to location [17H] is always written as 1. After a chip reset, these input/output lines remain at high levels or floating state (dependent on pull-high options). Each bit of these input/output latches can be set or cleared by SET [m].i and CLR [m].i (m=12H, 14H, 16H) instructions. Some instructions first input data and then follow the output operations. For example, SET [m].i, CLR [m].i, CPL [m], CPLA [m] read the entire port states
HT86R192
into the CPU, execute the defined operations (bit-operation), and then write the results back to the latches or the accumulator. Each line of port A has the capability of waking-up the device. The wake-up capability of port A is determined by OTP option. There is a pull-high option available for all I/O lines. Once the pull-high option is selected, all I/O lines have pull-high resistors. Otherwise, the pull-high resistors are absent. It should be noted that a non-pull-high I/O line operating in input mode will cause a floating state. By some different OTP options, there are 3 shared pins (PC.4, PC.5, and PC.6) in PC. They can be normal I/O pins or for special functions. The PC.4 is the external clock source of timer/event counter TMR0 if TMR0 is set to external clock mode, and the PC.5 is the external clock source of timer/event counter TMR1 if TMR1 is set to external clock mode. PC6 is pin-shared with XIN. The XIN and XOUT can be connected to a 32kHz crystal as the clock source of the timer counter TMR3 if the OTP option is set to enable 32kHz (RTC) crystal. Audio Output and Volume Control - DAL, DAH, VOL The HT86R192 provides one 12-bit voltage type DAC device for driving external 8W speaker through an external NPN transistor. The programmer must write the voice data to register DAL (27H) and DAH (28H). The 12-bit audio output will be written to the higher nibble of DAL and the whole byte of DAH, and the DAL3~DAL0 is always read as 0H. There are 8 scales of volume controllable level that are provided for the voltage type DAC output. The programmer can change the volume by only writing the volume control data to the higher-nibble of the VOL (29H), and the lower-nibble of VOL (29H) is always read as 0H.

Voice Control Register The voice control register controls the voice ROM circuit and DAC circuit, selects voice ROM latch counter, and controls 32kHz crystal to start in speed-up mode or not. If the DAC circuit is not enabled, any DAH/DAL output is invalid. Writing a 1 to DAC bit is to enable DAC circuit, and writing a 0 to DAC bit is to disable DAC circuit. If the voice ROM circuit is not enabled, then voice ROM data cannot be accessed at all. Writing a 1 to VROMC bit is to enable the voice ROM circuit, and writing a 0 to VROMC bit is to disable the voice ROM circuit. The bit 4 (LATCHC) is to determine what voice ROM address latch counter will be adopted as voice ROM address latch counter. The bit 7 (FAST) is to determine how to activate 32kHz crystal of TMR3s clock source. Voice ROM Data Address Latch Counter LATCH0H(18H)/LATCH0M(19H)/LATCH0L(1AH), LATCH1H(1BH)/LATCH1M(1CH)/LATCH1L(1DH) and voice ROM data register(2AH) The voice ROM data address latch counter is the handshaking between the microcontroller and voice ROM, Bit No. 0, 3, 5~6 Label 3/4 Unused bit, read as 0 Enable/disable DAC circuit (0= disable DAC circuit; 1= enable DAC circuit) The DAC circuit is not affected by the HALT instruction.

where the voice codes are stored. One 8-bit of voice ROM data will be addressed by setting 20-bit address latch counter LATCH0H/LATCH0M/LATCH0L or LATCH1H/LATCH1M/LATCH1L. After the 8-bit voice ROM data is addressed, a few instruction cycles (4ms at least) will be cost to latch the voice ROM data, then the microcontroller can read the voice data from LATCHD(2AH). Example: Read an 8-bit voice ROM data which is located at address 000007H by address latch 0 set clr mov mov mov mov mov mov call mov [26H].2 [26H].4 A, 07H A, 00H A, 00H Delay Time A, LATCHD Function ; Enable voice ROM circuit ; Select voice ROM address ; latch counter 0 ; ; ; ; Delay a short period of time ; Get voice data at 000007H
