Miami Mode
Configuration register E (address 0x04)
Max power correction variable
Max power correction
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.

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.
