Extra volume resolution configuration registers (addr 0x3F)
Extra volume resolution allows fine volume tuning in steps of 0.125 dB.
The feature is enabled when VRESEN = 1, as depicted in Figure 21. The overall channel
volume in this case is CxVol + CxVR (in dB).
Figure 21.
Extra resolution volume scheme
If VRESEN = 0 the channel volume is defined only by CxVol registers.
Fine tuning steps can be set according to the following table for channels 1, 2, 3:
Two different behaviors can be configured by VRESTG bit.
If VRESTG = 0 the CxVR contribution is applied immediately after the corresponding I2C
bits are written.
If VRESTG = 1 the CxVR bits are effective on channel volume only after the corresponding
CxVol register or master volume register is written (even to the previous values).
