MUTE (Pin No.13) [Digital-IN]
This is the output shut-off control terminal.
The terminal controls both channels at the same time. When MUTE terminal is set at "H" level, all of the output buffer
terminals, OUTPL, OUTML, OUTPR and OUTMR output "L" level, and this IC changes in mute state.
When MUTE terminal is set at "L" level, all of the output buffer terminals, OUTPL, OUTML, OUTPR and OUTMR output
the digital pulse signal.
PROT (Pin No.7) [Digital-OUT]
This is the warning signal output terminal for both overcurrent detection and high temperature detection. PROT terminal
outputs "H" level when either of those detection circuitries detects a hazardous state.
For the method of controlling MUTE terminal and SLEEP terminal by using PROT terminal, refer to "Overcurrent
detection function and high temperature detection function" on page 7.
