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 Table 14. The volume changes
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.
