Bit Name

Description

Default

Bit[2]

Clear 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

Bit[1]

Mute status (read-only)

Displays the status of the ADAV4601 mute.

0b = currently unmuting or unmuted

1b = currently muting or muted

Bit[0]

Mute flag (read-only)

Set to 1 when the ADAV4601 is in mute.

0b = unmuted

1b = muted
