ues. When this bit is enabled, the DAC will ramp down the volume prior to a filter-mode change and ramp
from mute to the original volume value after a filter-mode change according to the settings of the Soft and
Zero Cross bits in the Mode Control 3 register. When disabled, an immediate mute and unmute is per-
formed.
Loss of clocks or a change in the FM bits will always cause an immediate mute; unmute in these condi-
tions is affected by the RMP_UP bit.
Note: For best results, it is recommended that this feature be used in conjunction with the RMP_UP bit.

Channel A Volume = Channel B Volume (A=B)
Default = 0
0 - Disabled
1 - Enabled
Function:
The AOUTAx and AOUTBx volume levels are independently controlled by the A and the B Channel Vol-
ume Control Bytes when this function is disabled. The volume on both AOUTAx and AOUTBx are deter-
mined by the A Channel Attenuation and Volume Control Bytes (per A-B pair), and the B Channel Bytes
are ignored when this function is enabled.
