Default = 0

0 - Disabled

1 - Enabled

Function:

The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output

will be retained. The muting function is affected, similar to attenuation changes, by the Soft and Zero

Cross bits in the Transition and Mixing Control (address 02h) register. The MUTEC will go active dur-

ing the mute period if the Mute function is enabled for both channels.
