Serial audio input/output signals of the DSP (IC601) time-division multiplex multiple channels.
• 8 channels (channel 0 to 7) : Pins L1 and P7
• 2 channels (channel 0 to 1) : Pin N11
The signal is output from IC601 on the AU-342 board (pin number: shown below) and is returned to IC601 through
IC501 (pin number: shown below).
• The output signal from Pin L1 is checked in units of two channels, and the output signal from Pin N11 is checked
for each channel.
• The output signal from Pin N11 is sent through the internal speaker and the internal microphone.
