9.24
Four 8-bit values to program the volume attenuations. The range is from 0 to −66 dB and −∞ dB in steps of 0.25 dB.
Bits VL and VR are master volumes for the left and right channels.
Table 43 DAC volume settings
9.25
Four 8-bit values to program the volume attenuations. The range is from 0 to −60 dB and −∞ dB in steps of 0.25 dB.
When the DAC mixer is enabled, the signal from the digital interface can be controlled by bits VA and the signal from the
ADC can be controlled by bits VB.
