FUNCTIONAL DESCRIPTION
Control Registers
(1) CR0 (Basic operating mode)
Note: Initial Value: Reset state by PDN/RESET
B7 ...PCM Companding law select;
B6 ...Master clock frequency select;
B5 ...Power down (entire system);
B2 ...Not used
B1 ...Not used
B0 ...Power Down for Sound output amps: (SAO+, SAO–), or Receiver output amp (AOUT+,
B4, B3 ... Not used (These pins are used to test the device. They should be set to "0" during normal
CR0
Initial Value (Note)
When using this data for power down control, set pin PDN/RESET at “1”level.
The control registers are not reset by this signal.
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.
