Max power correction
Table 37.
Setting the MPC bit turns on special processing that corrects the STA339BWS 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.
