Pre-charge 4.
The pre-charge circuit will be ON for
50 ms and below and OFF.
Once OFF, output will be Hi-Z.
N.C.
You can use it as other pattern.
It is a control terminal that switches
whether to put the speaker amplifier
system into the state of operation or to
put it into the state of the standby.
Pin34 or Pin35 operates and the
speaker amplifier system operates at
Low.
When Pin34 and Pin35 all are High, it
completely enters the state of the
standby, and most circuit currents are
0 in this IC.
Please refer to the
Mode Table for the mode setting.

You can use it as other pattern.
Terminal for testing.
Please connect to Ground.
