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.
