OKI Semiconductor
CR1
Initial Value
B7, B6….. Selection of an input amplifier to encoder
Amplifiers which are not selected are powered down and their outputs go in the high impedance
state.
B5, B4….. Selection of an output amplifier
Amplifiers which are not selected are powered down and their outputs go in the high impedance
state.
B3 ……. Short frame synchronous interface select
B2 ……. Not used. When writing data, write “0”.
B1 ……. Analog switch control
B0 ……. Receive side PAD
(B7, B6) = (0, 0): MIC1
(B5, B4) = (0, 0): EXTO
= (0, 1): MIC2
= (1, 0): MIC3
= (1, 1): No input
= (0, 1): EAR1O
= (1, 0): EAR2O
= (1, 1): No output

0: No pad
1: A pad of 12 dB loss is inserted in the receive side voice path.
0: Long frame synchronous interface,
1: Short frame synchronous interface
0: The SWB pin is internally connected to the SWA pin.
1: The SWB pin is internally connected to the SWC pin.
The unconnected pins go in a high impedance state.
