Register 16398 (0x400E), Record Gain Left PGA
The record gain left PGA control register controls the left channel
input PGA. This register configures the input for either differ-
ential or single-ended signals and sets the left channel input
recording volume.
Bits[7:5], Left Input Gain
These bits set the left channel analog microphone input PGA gain.
Bit 2, Single-Ended Left Input Enable
If this bit is high (enabled), a single-ended input can be input on
the LMIC pin and gained by the PGA. The positive differential
input pin (LMICP) is disabled, and the complementary input of
the PGA is switched to common mode.
Bit 1, Record Path Left Mute
This bit mutes the left channel input PGA.
Bit 0, Left PGA Enable
This bit enables the left channel input PGA
