MUTE PIN DECODE
The MUTE pin can either be used as an output or an input. When used as an input the MUTE pins
action can be controlled by setting the DZFM bit to select the corresponding DAC for applying the
MUTE to. As an output its meaning is selected by the DZFM control bits. By default selecting the
MUTE pin to represent if DAC1 has received more than 1024 midrail samples will cause the MUTE
pin to assert a softmute on DAC1. Disabling the decode block will cause any logical high on the
MUTE pin to apply a softmute to all DAC’s.
