Description
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.
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.
