B7 ...PCM Companding law select:
B6 ...Master clock frequency select:
B5 ...Power down (whole system):
When using this data for power down control, pin
PDN/RESET
should be set at
“H”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 including the op-amps of GSX3, GSX4 and comparator): 0/
Power on, 1/Power down
B2 ...Not used
B1 ...PCM interface linear code select:
0/Companding law selected by CR0-B7
1/14-bit Linear code (2's complement) in spite of the value of CR0-B7
B0 ...Power Down for Sounder output amps: (SAO), or Receiver output amp (AOUT, VFRO ):
When this data is set to digital “1”, the circut which is not selected by CR4-B5 are at the
power down state.
When this data is set to digital "0", sounder amplifiers and receiver amplifiers are in the
power-on state.
