ADC High Pass Filter
00 => Disabled
01 => 3dB point = 0.0045 x Fs
10 => 3dB point = 0.0125 x Fs
11 => 3dB point = 0.025 x Fs
Note: Fs is ADC sample rate

ADCIN
R/W
00
ADC Input Mux
00 => ADC Input = Single-ended input MIC
01 => ADC Input = Single-ended input AUX
10 => ADC Input = Differential input MICIN and AUX
11 => ADC Input = Differential input MICIN and AUX
D11D10
WLEN
R/W
00
Codec Word Length
00 => Word length = 16 bit
01 => Word length = 20 bit
10 => Word length = 24 bit
11 => Word length = 32 bit
D9D8
DATFM
R/W
00
Digital Data Format
00 => I2S mode
01 => DSP mode
10 => Right justified
11 => Left justified
Note: Right justified, valid only when the ratio between DAC and ADC sample rate is an integer.
e.g., ADC = 32 kHz and DAC = 24 kHz or vice-versa is invalid for right-justified mode.
