Default:
0 - Disabled
Function:
The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output
will be retained. The muting function is effected, similiar to attenuation changes, by the Soft and Zero
Cross bits in the Volume and Mixing Control register. The MUTEC will go active during the mute pe-
riod if the Mute function is enabled for both channels.
