Microphone

The MCBSTM32C board includes a standard stereo microphone mini-connector for input to the on-board Cirrus CS42L52 CODEC. Installing jumpers J1 and J3 applies a bias voltage separately to the left and right microphone inputs (AIN3A and AIN3B). The bias voltage (MICBIAS) value is a software configurable parameter within the CODEC.
