Voice Trigger:

The voice circuitry will be Triggered in the rising edge of TRG signal. The Voice section address must be placed on I/OA

and I/OB port.

I/OB2 I/OB1 I/OA4 I/OA3 I/OA2 I/OA1

(MSB)

(LSB)

a)In power on state, TRG signal is reset to "LOW" level. TRG will stay at low level until the program set it to "HIGH" level.

b) Before triggering the voice circuitry, used the OIOA and OIOB instruction to place the voice section address on I/OA and

I/OB port. The voice section address couldn't be changed until the rising edge of TRG signal.

c) After triggering voice, I/OA and I/OB ports must output 3F data or set to input mode. If not, there will be a standby

current problem.

d) Example of playing voice subroutine:

LDS 3,1

LDS 4,A

OIOB 3 ; place voice section address to i/o port

OIOA 4

RF 4 ; trigger voice

SF 4

LDS 3,3

LDS 4,F

OIOA 4 ; output 3F data to I/O port
