FUNCTIONAL DESCRIPTION
Voice Synthesizer
How to select a voice start address
There is a voice start address and RC, composed
of 8-bit to select a voice start address. Voice start
address is 16 bits. However, RC register can points
only upper 8 bits in voice start address in partial.
Lower 8-bit is always fixed "0". Refer to "RC
register".
Minimum unit (shortest block) is equal voice ROM
capacity. Each minimum unit is composed of 256
steps. Refer to Fig.9.
Core CPU detects the status whether voice
synthesizer run or not, by reading the content of
P3
3
flag. (P3
3
flag is "1" during voice generation.)
Terminator (11111B) can be set as a voice data in
the voice ROM.
When controller found a terminator, immediately
stops voice and reset a flag.
When reached the bottom of the voice data
address, voice data address automatically becomes
0000
H
and voice continuously generates until come
across a terminator.
CPU can reset the P3
3
flag and stop voice
generation by force.
NOTE :
Voice ROM data "11111" means terminator of voice data.
That is, an encoder must encode voice data except "11111".
Voice sampling frequency (5 kHz / 7 kHz)
In case of sampling frequency is 5 kHz, total
generation period becomes 12.8 s. In case of 7
kHz, it's 9.1 s.
Voice sampling frequency (5 kHz or 7 kHz) is
selected by RD3 register. In case of RD3 is "0",
voice sampling frequency becomes 7 kHz. In case
of RD3 is "1", it's 5 kHz.
RC register
The RC register is composed of 8-bit. It can points
only upper 8 bits in the voice start address as
shown below. The data is filled with both A and X
registers.
NOTE :
A voice start address is corresponding to the RC register (8
bits). Maximum 256 (SM5M2) pieces of voice start address
can be selected. Each voice start address is based on
multiple number of 100H. When voice generates, P33 flag
becomes "1".
First set the sampling rate of the voice synthesizer.
The voice synthesizer start address is corre-
sponding to the RC register and the 8 bits in the
RC register are obtained by A and X register. After
setting the P3
3
voice flag High, the voice
synthesizer would start playing. After detect P3
3
Low, the voice synthesizer could play the next
section of voice.
