When this bit is cleared, no de-emphasis is applied to the DAC outputs.
Function:
When set, enables the Auto-Mute function.
Function:
When this bit is set, the output of the ADC for the selected channel will be muted.
Function:
The MUTEA and MUTEB pins (pins 24 and 21) are active low by default. When this bit is set, these pins
are active high.
Function:
When this bit is set, the output of the DAC for the selected channel will be muted.
