Register description
40/72
For each configuration the PWM from the digital driver is mapped in a different way to the
power stage:
2.0 channels, two full bridges (OCFG = 00)
On channel 3 line out (LOC bits = 00) the same data as channel 1 processing are sent. On
channel 4 line out (LOC bits = 00) the same data as channel 2 processing are sent. In this
configuration, no volume control or EQ have effect on channel 3 and 4.
