01 = 20-bit
10 = 24-bit
11 = 32-bit (not available in Right Justified mode)
ADC BCLK Polarity
0 = ADCBCLK not inverted – data latched on rising edge of BCLK
1 = ADCBCLK inverted – data latched on falling edge of BCLK
ADC LRCLK Polarity
0 = ADCLRCLK not inverted
1 = ADCLRCLK inverted
ADC Enable
0 = ADC disabled
1 = ADC enabled
ADC Left/Right Swap
0 = Normal
1 = Swap left channel data into right channel and vice-versa
ADCL and ADCR Output Signal Inversion
0 = Output not inverted
1 = Output inverted
ADC Data Output Select
00 = left data from ADCL, right data from ADCR (Normal Stereo)
01 = left data from ADCL, right data from ADCL (Mono Left)
