Function:
Default = 0 dB (No Attenuation)
The digital volume control allows the user to attenuate the signal in 1 dB increments from 0 to -90 dB.
Volume settings are decoded as shown in Table 7. The volume changes are implemented as dictated
by the Soft and Zero Cross bits in the Transition and Mixing Control (address 02h) register. All volume
settings less than - 94 dB are equivalent to enabling the Mute bit.
