Table 50 shows the polarities of the outputs in various configurations.
Unless otherwise stated, polarity is shown with respect to left DAC output in non-inverting mode.
Note that only registers relating to the mixer paths are shown here (Mixer enables, volume settings,
output enables etc are not shown).
Note that differential output should not be set up by combining outputs in boost mode with outputs
which are not in boost mode as this would cause a DC offset current on the outputs.
