Initial Value
Note : Initial Value : Reset state by
PDN/RESET
B7 ...PCM Companding law select;
B6 ...Master clock frequency select;
B5 ...Power down (entire system);
When using this data for power down control, set pin
PDN/RESET
at “1” level.
The control registers are not reset by this signal.
B4 ...Power down (Transmit only);
0/Power on, 1/Power down
B3 ...Power down (Receive only);
0/Power on, 1/Power down
B2 ...Not used
B1 ...Not used
B0 ...Power Down for Sound output amps: (SAO+, SAO–), or Receiver output amp (AOUT+,
AOUT–, VFRO );
If this data is set to digital “1”, either a pair of sound amplifiers or a pair of reciver
amplifiers enters the power down state depending on the set data on CR4-B5.
If this data is set to digital "0", sound amplifiers and receiver amplifiers are in the power-
on state.
