ADC AUDIO INTERFACE CLOCK CONFIGURATION
The WM8595 ADC has an independent audio interface which can be configured to select the
required signals from any of the digital audio ports. The audio interface is not restricted to take each
signal from the same digital audio port, although the BCLK and LRCLK signals are selected together.
The MCLK is always an input to the ADC audio interface is selected using ADCMCLK_SEL[2:0]. The
BCLK and LRCLK are always selected together, and can be either an input to the ADC audio
interface (when the ADC is in slave mode) or an output from the ADC audio interface (when the ADC
is in master mode). BCLK and LRCLK are selected using ADCWORDCLK_SEL[2:0].
