SPI REGISTER DETAILED DESCRIPTION
Volume
The volume register increments digitally in 0.5dB
steps. The volume range is from -94.5db to +25dB. The
final used code in the sequence it termed a soft mute
and sets the volume to -95dB. The code sequence
applies equally to left and right volume controls. The
bit numbers for the volume controls are 0 to 8 for the
left channel and 9 to 17 for the right.
The control of the volume should not jump directly
from one level to the next but should pass through all
0.5dB steps between the two required levels.

Bass
The bass register increments digitally in steps of 1dB.
The range is from 0dB to
