Programmable-Gain Adjustment for Microphone
Sources (PGAML/PGAMR)
PGAML/PGAMR configures the programmable-gain
adjustment setting for the microphone left/microphone
right input. Code 0x00 is maximum gain while 0x1F is
maximum attenuation. Table 27 lists the gain setting for
each code.
Microphone Preamplifier Enable (PALEN/PAREN)
1 = Additional +20dB of gain applied to microphone
inputs by the preamplifier
0 = 0dB of gain applied by the microphone preamplifier
Preamplifier gain adds to the gain set by PGAML/
PGAMR. See the Microphone Amplifiers section.

Microphone Mute (MMIC)
1 = Mute all microphone inputs.
0 = Mute disabled.
External Microphone Mode (MEXT)
1 = External microphone inputs.
0 = Internal microphone inputs.
Resistor Bias Enable (RBEN)
1 = Internal bias resistors for EXTMICBIASL and
EXTMICBIASR connected.
0 = Internal bias resistors disconnected.
Microphone Bias Output Impedance Select (RBIAS)
1 = 470
Ω.
0 = 2.2k
Ω.
Select 2.2k
Ω when using electret or amplified micro-
phones. Select 470
Ω when using an external RC filter
near the headset jack.
