Digital mute setting. If this bit is logic 0, then the digital output is not muted; if this bit is
logic 1, then the digital output is muted.
Power control digital output. If this bit is logic 0, then the digital output is in Power-down
mode; if this bit is logic 1, then the digital output is in power-on mode. The registers have
their own clock, which means that there cannot be a dead-lock situation.
reserved
Input selector for digital output. Value to select the input signal for the digital output. The
default input will be chosen if in an application an invalid data signal is selected:
reserved
Digital output format. Value to set the digital output format:
