Clear mute
Mute status (read-only)
Mute flag (read-only)
Description
Set to 1 to unmute the ADAV4601 when the external pin has been used to mute the
part and the mute clear select bit is set. Having performed the required action, this bit
automatically resets to 0.
0b = no change
1b = clear pin mute
Displays the status of the ADAV4601 mute.
0b = currently unmuting or unmuted
1b = currently muting or muted
Set to 1 when the ADAV4601 is in mute.
0b = unmuted
1b = muted
