Table 44 Treble settings
Table 45 Normal bass boost settings; note 1
Note
1. The bass boost setting is only effective when bit BASS_SEL = 0.
6 BB_FIX Resonant bass boost coefficient. If this bit is logic 0 then the resonant bass boost
coefficient is finished loading; if this bit is logic 1 then the resonant bass boost coefficient
is loading to register.
5 and 4 TRR[1:0] Treble settings right. Value to program the right treble setting. The used filter set is
selected by the sound feature mode bits M1 and M2 (see Table 44).
3to0 BBR[3:0] Normal bass boost settings right. Value to program the right bass boost settings. The
used filter set is selected by the sound feature mode bits M1 and M2 (see Table 45).
