Bits[1:0], On-Chip ADC Data Selection in TDM Mode
These bits set the position of the ADC output channels on a TDM
stream. In TDM 4 mode, valid settings are first pair or second
pair. In TDM 8 mode, valid settings are first pair, second pair,
third pair, or fourth pair. These bits should be set in conjunction
