Sound feature mode. Value to program the sound processing filter sets (modes) of bass
boost and treble:
Treble settings left. Value to program the left channel treble setting. Both left and right
channels will follow the left channel setting when bit BASS_SEL = 1. The used filter set is
selected with the sound feature mode bits M1 and M2 (see Table 44).
Normal bass boost settings left. Value to program the left bass boost settings. The
used filter set is selected by the sound feature mode bits M1 and M2 (see Table 45).
Resonant bass boost. If this bit is logic 0 then the resonant bass boost is enabled; if this
bit is logic 1 then the resonant bass boost is disabled.
