MIC Bias Output Impedance Adjustment
Controls an adjustable output impedance for the microphone
bias. If this is set to zero the micbias block is powered off and
the output is highZ.
0x0 = Powered off
0x1 = 2Kohm
0x2 = 4Kohm
0x3 = 8Kohm
Reserved
MIC Bias Voltage Adjustment
Controls an adjustable bias voltage for the microphone bias
amp in 250mV steps. This bias voltage setting should be no
more than VDDA-200mV for adequate power supply rejection.
0x0 = 1.25V
...
0x7 = 3.00V
Reserved
MIC Amplifier Gain
Sets the microphone amplifier gain. At 0dB setting the THD
can be slightly higher than other paths- typically around
~65dB. At other gain settings the THD will be better.
0x0 = 0dB
0x1 = +20dB
0x2 = +30dB
0x3 = +40dB
