Max power correction
Table 37.
Setting the MPC bit turns on special processing that corrects the STA50x power device at
high power. This mode should lower the THD + N of a full DDX system at maximum power
output and slightly below. If enabled, MPC is operational in all output modes except tapered
(OM[1,0] = 01) and binary. When OCFG = 00, MPC will not effect channels 3 and 4, the line-
out channels.

Max power correction variable:
0: Use standard MPC coefficient
1: Use MPCC bits for MPC coefficient
Max power correction: setting of 1 enables power
bridge correction for THD reduction near maximum
power output.
