CHS = 0 selects the left-channel coefficient’s data block.
CHS = 1 selects the right-channel coefficient’s data block.
When set to 1, this bit indicates that the left- and right-channel coefficients are equal. This
shortens the coefficients’ setup sequence, because only the left-channel coefficients need to be
addressed and set up. The right-channel coefficients are fetched from the left-channel memory.
Enables mixer ADC data to be summed into the PCM stream.
0 = No loopback allowed (default).
1 = Enable loopback.
When set to 1, this bit disables the equalizer function (allows all data to pass through). The reset
default sets this bit to 1, disabling the equalizer function until the biquad coefficients can be
properly set.
