AudioOutputandVolumeControl
DAL,DAH,VOL
The HT86XXX provides one 12-bit current type DAC de-
vice for driving external 8
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 DAL3~0 is always
read as 0H. There are 8 scales of volume controllable
level that are provided for the current 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
VOICEC (26H)
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/DALoutput 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
bitistoenablethevoiceROMcircuit,andwritinga 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 TMR3 s 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 hand-
shaking between the microcontroller and voice ROM,
where the voice codes are stored. One 8-bit of voice
ROM data will be addressed by setting 24-bit address
latch counter LATCH0H/LATCH0M/LATCH0L or
LATCH1H/LATCH1M/LATCH1L. After the 8-bit voice
ROM data is addressed, a few instruction cycles (4 s 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 lo-
cated at address 000007H by address latch 0
