Description
Used to control the software mute.
0b = unmute
1b = mute
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
Description
00b = PWM ready forced low
01b = PWM ready forced high
10b = PWM ready late
11b = PWM ready early
Always write as 0 if writing to this register.
