BCLK polarity
0=normal
1=inverted
right, left and i2s modes – LRCLK polarity
1 = invert LRCLK polarity
0 = normal LRCLK polarity
DSP Mode – mode A/B select
1 = MSB is available on 1st BCLK rising edge after
LRC rising edge (mode B)
0 = MSB is available on 2nd BCLK rising edge
after LRC rising edge (mode A)

10=I
11= DSP/PCM mode
Controls whether DAC data appears in ‘right’ or
‘left’ phases of LRC clock:
0=DAC data appear in ‘left’ phase of LRC
1=DAC data appears in ‘right’ phase of LRC
Controls whether ADC data appears in ‘right’ or
‘left’ phases of LRC clock:
0=ADC data appear in ‘left’ phase of LRC
1=ADC data appears in ‘right’ phase of LRC
Selects between stereo and mono device
operation:
0=Stereo device operation
1=Mono device operation. Data appears in ‘left’
phase of LRC
