Loopback
(a) Loopback mode (ADF_LB = 1)
Internal connect between ADOUT and DAIN, This enables the MIC input to be output to the line or speaker without
recording or playback operation. In this case, external output through ADOUT is enabled but external input through
DAIN is disabled.
(b) Standard mode (ADF_LB = 0)
The DAIN external input is enabled and the internal switch for ADOUT and DAIN is released.

Windcut HPF (1st order)
WIND_CUT [5:4] turns off the high-pass filter (through) when initialized to (00).
Regardless of the sampling frequency (fs), the cutoff frequency (fc) is 400Hz when WIND_CUT [5:4] is set at 11,
300Hz at 10, 200Hz at 01 and OFF at 00.
