HT86R192
Functional Description
Execution Flow
Program Counter - PC
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.
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.
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.

subroutine, the PC manipulates the program transfer by
loading the address corresponding to each instruction.
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.
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.
· 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.
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.
· 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.
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 8192´16 bits. Certain locations in the
program memory are reserved for special usage:
· Location 014H
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.
· Location 000H
This area is reserved for program initialization. The
program always begins execution at location 000H
each time the system is reset.
Table Location
· Location 004H
Any location in the ROM space can be used as look up
tables. The instructions ²TABRDC [m]² (used for any
bank) and ²TABRDL [m]² (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.
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.

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
²CALL² is subsequently executed, stack overflow occurs and the first entry is lost.
The general purpose data memory, addressed from
30H~FFH, is used for data and control information under instruction commands.
Data Memory - RAM
The areas in the RAM can directly handle the arithmetic,
logic, increment, decrement, and rotate operations. Except some dedicated bits, each bit in the RAM can be
set and reset by ²SET [m].i² and ²CLR [m].i². They are
also indirectly accessible through the memory pointer
register 0 (MP0:01H) or the Memory Pointer register 1
(MP1:03H).
The data memory is designed with 208´8 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.
The special function registers include an Indirect addressing register (R0:00H), Memory pointer register

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 ²HALT² instruction. The Z, OV, AC, and C flags reflect the status of the
latest operations.
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.
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.
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.
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.
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)
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.
· Logic operations (AND, OR, XOR, CPL)
· Rotation (RL, RR, RLC, RRC)
· Increment and Decrement (INC, DEC)
· Branch decision (SZ, SNZ, SIZ, SDZ etc)
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.

14H will occur. The related interrupt request flag (T3F)
will be reset and the EMI bit cleared to disable further interrupts.
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.
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.
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.
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 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 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.
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.
It is recommended that application programs do not use
²CALL² 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 ²CALL² subroutine if used in the interrupt
subroutine will corrupt the original control sequence.
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.
Interrupt Source
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

the crystal and to get a frequency reference, but two external capacitors in OSC1 and OSC2 are required.
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.
There is another oscillator circuit designed for Timer3¢s
clock source as the RTC time base which is determined
by OTP option. If the OTP option determines that
Timer3¢s clock source is from a 32kHz crystal, then a
32kHz crystal should be connected to XIN and XOUT.

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
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

flags, the reason for the chip reset can be determined.
The PDF flag is cleared when the system powers-up or
executes the ²CLR WDT² instruction, and is set when
the ²HALT² 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.
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.
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.
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 ²chip reset² and set the status bit ²TO². Whereas in
the HALT mode, the overflow will initialize a ²warm re set² 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 ²HALT² instruction. The software instruction
is ²CLR WDT² and execution of the ²CLR WDT² instruction will clear the WDT.
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 ²1² 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.

· WDT time-out reset during normal operation
The WDT time-out during HALT is different from other
chip reset conditions, since it can perform a ²warm re set² 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 ²initial condition² when the reset conditions are met. By examining
the PDF flag and TO flag, the program can distinguish
between different ²chip resets².

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.

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.
The TMR0C is the Timer/Event Counter 0 control register, which defines the Timer/Event Counter 0 options.
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.
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 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 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.
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
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.

clock source of TMR3 can be from internal instruction
cycle (T1) or external 32kHz crystal which is connected
to XIN and XOUT. The TMR3¢s clock source is determined by OTP option. If the 32kHz crystal is enabled,
then TMR3¢s clock source is 32kHz which is from XIN
and XOUT. If the 32kHz crystal is disabled, then TMR3¢s
clock source is internal T1.
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.
Timer Counter 3 (RTC Time Base)
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 TMR3¢s clock source.
The timer counter TMR3 is an 8-bit programmable
count-up counter. Its counting is as the same manner as
Timer Event Counter 0/1 and Timer Counter 2, but the

into the CPU, execute the defined operations
(bit-operation), and then write the results back to the
latches or the accumulator.
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 ²MOV A, [m]² (m=12H,14H
or 16H). For output operation, all the data is latched and
remains unchanged until the output latch is rewritten.
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.
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 ²1². The input source
also depends on the control register. If the control register bit is ²1², the input will read the pad state. If the control register bit is ²0², the contents of the latches will
move to the internal bus. The latter is possible in the
²read-modify-write² instruction.
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
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 ²1².
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 ²0H². 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 ²0H².
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 ²SET [m].i² and ²CLR [m].i² (m=12H, 14H,
16H) instructions.
Some instructions first input data and then follow the
output operations. For example, ²SET [m].i², ²CLR
[m].i², ²CPL [m]², ²CPLA [m]² read the entire port states

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).
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 ²1² to DAC bit is to enable DAC circuit,
and writing a ²0² 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 ²1² to VROMC
bit is to enable the voice ROM circuit, and writing a ²0² 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 TMR3¢s clock source.

DAA [m]
Decimal-Adjust accumulator for addition
Description
The accumulator value is adjusted to the BCD (Binary Coded Decimal) code. The accumulator is divided into two nibbles. Each nibble is adjusted to the BCD code and an internal
carry (AC1) will be done if the low nibble of the accumulator is greater than 9. The BCD adjustment is done by adding 6 to the original value if the original value is greater than 9 or a
carry (AC or C) is set; otherwise the original value remains unchanged. The result is stored
in the data memory and only the carry flag (C) may be affected.
Operation
If ACC.3~ACC.0 >9 or AC=1
