Register 16399 (0x400F), Record Gain Right PGA
The record gain right PGA control register controls the right
channel input PGA. This register configures the input for either
differential or single-ended signals and sets the right channel
input recording volume.
Bits[7:5], Right Input Gain
These bits set the right channel analog microphone input PGA gain.
Bit 2, Single-Ended Right Input Enable
If this bit is high (enabled), a single-ended input can be input on
the RMIC pin and gained by the PGA. The positive differential
input pin (RMICP) is disabled, and the complementary input of
the PGA is switched to common mode.
Bit 1, Record Path Right Mute
This bit mutes the entire right channel input PGA.
Bit 0, Right PGA Enable
This bit enables the right channel PGA.
