FUNCTION

D25 = '1' negates the audio in channel-2 (Right Channel). This is to reduce

supply pumping when Left and Right channels are SE mode. RIght channel

speaker should be connected in reverse order: Positive speaker terminal to

ground and negative terminal to audio output (OUT_B) (1)

Bits [D29:D24] can be used to negate audio volume for channels [6:1] respectively and bits are defined as '0' means NO Volume

Negation and '1' means Volume Negation.

PWM Output Mux Register

The table below shows a settings like that.

In 2.1 Mode, PWM channel1 should be muxed to Out_A, channel2 to Out_B, and channel 4 to Out_C and

channel 5 to Out_D where Out_A and Out_B for SE channels and OUT_C and OUT_D are the BTL pairs.
