Extra volume resolution configuration registers (address
0x3F; 0x40)
Extra volume resolution allows fine volume tuning by steps of 0.125 dB.
The feature is enabled when VRESEN=1, as depicted in Figure 41. The overall channel
volume in this case will be CxVol+CxVR (in dB), while the master volume will be
MVOL+MVR (in dB).
Figure 41.
Extra resolution volume scheme
If VRESEN = 0 the channel volume will be defined only by the CxVol registers.
Fine tuning steps can be set according to the following table for channels 1, 2,3, and master
volume.
Table 164.
