Access:
R/W in Two Wire Mode and write only in SPI.
Default:
0 - 0 dB (No attenuation)
Function:
The Volume Control allows the user to alter the signal level in 1 dB increments from +12 to -96 dB, when
the INDVC bit is disabled. When INDVC is enabled, the Volume Control can be altered in 1 dB increments
from 0 to -96 dB. Volume settings are decoded as shown in Table 13, using a 2’s complement code. The
volume changes are implemented as dictated by the Soft and Zero Cross bits in the Analog I/O Control
register. All volume settings less than -96 dB are equivalent to muting the channel.
