Tri-State Serial Port Interface
Determines the state of the serial port drivers.
Notes:
1. Slave/Master Mode is determined by the M/S bit in
2. When the serial port is tri-stated in master mode, the ADC and DAC serial ports are clocked internally.
Speaker/Headphone Switch Invert
Determines the control signal polarity of the SPK/HP_SW pin.
MIC Bias Level
Sets the output voltage level on the MICBIAS output pin.
ADC Input Select
Selects the specified analog input signal into ADCx.
