This register sets the gain of each band of the equalizer. If COEFSEL=0, then the register level of EQGAIN0 to 4 is effective.
If COEFSEL=1, then value of the EQGAIN0B to EQGAIN4B register becomes effective.
This register can set EQ gain from -71.5dB to 12.0dB(step by step 0.5dB). Also it can set MUTE.
EQ can work as a notch filter by MUTE setting.
