LOOPBACK
COMPANDING
Setting the LOOPBACK register bit enables digital loopback. When this bit is set the output data
from the ADC audio interface is fed directly into the DAC data input.
The WM8980 supports A-law and -law and companding and linear mode on both transmit (ADC)
and receive (DAC) sides. Companding can be enabled on the DAC or ADC audio interfaces by
writing the appropriate value to the DAC_COMP or ADC_COMP register bits respectively.
