Beep
Beep sound signals from microcomputer can be received by the beep input terminal (19-pin).
The PWA and PWB of the power amplifier during power mute are turned OFF, and the beep signal input
from BEEP-IN (19-pin) is output from the BEEP-OUT terminal (10/11-pin) as fixed current, after passing
through the converter and current amplification stage. Connecting this terminal to the headphone load
outputs the beep sound.
If the beep sound is not input, fix the BEEP-IN (19-pin) terminal to GND level.
