for example:
In the sum of both mixing inputs exceeds 100 %, clipping may occur in the
successive audio processing.

bit[1:0]
In order to achieve more output power a single loudspeaker can be connected
as a bridge between pins OUTL and OUTR. In this mode bit[15] and bit[14]
must be set.
Bass
bit[15:8]
Higher resolution is possible, one LSB step results in a gain step of about
1/8 dB.
With positive bass settings clipping of the output signal may occur. Therefore,
it is not recommended to set bass to a value that, in conjunction with volume,
would result in an overall positive gain.
The settings require: max (bass, treble) + loudness + volume
