Description
4
POPMODE
Pop suppression circuit power saving mode. The pop suppression circuits charge faster in normal operation;
however, after they are charged, they can be put into low power operation.
0 = normal (default).
1 = low power.
3
POPLESS
Pop suppression disable. The pop suppression circuits are enabled by default. They can be disabled to save
power; however, disabling the circuits increases the risk of pops and clicks.
0 = enabled (default).
1 = disabled.

[7:2]
MONOVOL[5:0]
Mono output volume control. Each 1-bit step corresponds to a 1 dB increase in volume. If MX7[1:0] in Register R28
is set for common-mode output, volume control is disabled. See Table 72 for a complete list of the volume settings.

MONOM
Mono output mute (active low).
0 = mute.
1 = unmute (default).
0
MOMODE
Headphone mode enable. If MX7[1:0] in Register R28 is set for common-mode output for a capless headphone
configuration, this bit should be set to 1 ( headphone output).
0 = line output (default).
1 = headphone output.
