DESIGNATOR
In TDM mode, SDOUT_SEL1 and SDOUT_SEL 0 extract two stereo pairs from the CS5364 TDM stream,
convert the data to Left-Justified PCM format and send the data to the CS8406 data input pin.
In PCM mode, SDOUT_SEL1 and SDOUT_SEL 0 select which SDOUT pin of the CS5364 is sent to the
CS8406.
TDM2PCM/PCM selects the clock source for the CS8406.
