Max power correction
Table 37.
Setting the MPC bit turns on special processing that corrects the STA339BW power device
at high power. This mode should lower the THD+N of a full FFX 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.

0: Use standard MPC coefficient
1: Use MPCC bits for MPC coefficient
Setting of 1 enables Power Bridge correction for
THD reduction near maximum power output.
