B7, B6….. Selection of an input amplifier to encoder

(B7, B6) = (0, 0): MIC1

= (0, 1): MIC2

= (1, 0): MIC3

= (1, 1): No input

Amplifiers which are not selected are powered down and their outputs go in the high impedance

state.

B5, B4….. Selection of an output amplifier

(B5, B4) = (0, 0): EXTO

= (0, 1): EAR1O

= (1, 0): EAR2O

= (1, 1): No output

Amplifiers which are not selected are powered down and their outputs go in the high impedance

state.

B3 ……. Short frame synchronous interface select

0: Long frame synchronous interface,

1: Short frame synchronous interface

B2 ……. Not used. When writing data, write “0”.

B1 ……. Analog switch control 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.

B0 ……. Receive side PAD

0: No pad

1: A pad of 12 dB loss is inserted in the receive side voice path.
