6.3.1
Channel A Volume = Channel B Volume (VOLB=A) Bit 7
Function:
When set to 0 (default) the AOUTA and AOUTB volume levels are independently controlled by the A and
the B Channel Volume Control Bytes.
When set to 1 the volume on both AOUTA and AOUTB are determined by the A Channel Attenuation and
Volume Control Bytes, and the B Channel Bytes are ignored.
6.3.2
Invert Signal Polarity (Invert_A) Bit 6
Function:
When set to 1, this bit inverts the signal polarity of channel A.
When set to 0 (default), this function is disabled.
6.3.3
Invert Signal Polarity (Invert_B) Bit 5
Function:
When set to 1, this bit inverts the signal polarity of channel B.
When set to 0 (default), this function is disabled.
