Description
It is a control terminal that determines
the BEEP detector is in a state of
operation or standby.
The BEEP sound detection operates at
Pin 29 high.
When Pin 29 is low, the BEEP sound
detection is turned off.
Please refer to the control terminal mode
table of Page No.11 for the mode setting.
It is a control terminal that determines
the speaker amplifier system is in a state
of operation or standby.
The speaker amplifier system operates at
Pin 30 or Pin 31 high.
When Pin 29, Pin 30, Pin 31, Pin 32, Pin
33, Pin 34 and Pin 48 all are low, it
completely enters the state of standby,
and most circuit currents are 0 in this IC.
Please refer to the control terminal mode
table of Page No.11 for the mode setting.
It is a control terminal that determines
the L-channel microphone amplifier
system is in a state of operation or
standby.
At Pin 32 high, the L-channel.
microphone amplifier turns on, and turns
off at low.
Please refer to the control terminal mode
table of Page No.11 for the mode setting.
