* The initial value means a value which is set when the device is reset using the RESET signal.
B7: .............. PCM interface companding selection
0: m-law 1: A-law
B6: .............. Not used
B5: .............. Power down (entire unit) 0: Power ON 1: Power down
ORed with the inverting external power down signal PDN3. When using
this data, set PDN3 to "1".
B4: .............. Power down (transmit side only) 0: Power ON 1: Power down
B3: .............. Power down (receive side only) 0: Power ON 1: Power down
B2: .............. Output from VFRO and SAO at a time
0: Receive side output signals are output from a pin selected by B1.
1: Receive side output signals are output from VFRO and SAO at a time.
B1: .............. Receive side output switch control
0: Receive side output signals appear on the SAO (Sounder Amplifier
Output) pin.
1: These signals appear on the VFRO (Receiver Amplifier Output) pin.
B0: .............. Power down control for sounder output amplifier (SAO) and receiver
output amplifier (VFRO).
0: When SAO is selected by CR0 - B1, VFRO is powered down.
When VFRO is selected, SAO is powered down.
1: Both SAO and VFRO are powered ON.
