0 - 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 11. The volume changes are implemented as dic-
tated by the Soft and Zero Cross bits in the Volume and Mixing Control register. All volume settings
less than - 94 dB are equivalent to enabling the Mute bit.
