• Manufacturer: APLUS [Aplus Intergrated Circuits]

LCD Common Plate Usage:
Voice Trigger:
Absolute Maximum Rating:
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.
b) Before triggering the voice circuitry, used the OIOA and OIOB instruction to place the voice section address on I/OA and
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
d) Example of playing voice subroutine:
current problem.
IOA1-IOA4
IOB1-IOB4
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.
