Function:
The Digital Volume Control registers allow independent control of the signal levels in 0.5 dB incre-
ments from 0 to -127 dB. Volume settings are decoded as shown in
are implemented as dictated by the Soft and Zero Cross bits (SZC[1:0]). All volume settings less than
-127 dB are equivalent to enabling the MUTE bit for the given channel.
When enabled, these bits will invert the signal polarity of their respective channels.
The AOUTAx and AOUTBx volume levels are independently controlled by the A and the B Channel
Volume Control registers when this function is disabled. The volume on both AOUTAx and AOUTBx
are determined by the A Channel Volume Control registers (per A-B pair), and the B Channel Volume
Control registers are ignored when this function is enabled.
