MPC
Setting of 1 enables Power Bridge correction for
THD reduction near maximum power output.
Setting the MPC bit turns on special processing that corrects the STA335W 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.

AME
0: Normal FFX operation.
1: AM reduction mode FFX operation
STA335W features aFFX processing mode that minimizes the amount of noise generated in
frequency range of AM radio. This mode is intended for use when FFX is operating in a
device with an AM tuner active. The SNR of the FFX processing is reduced to approximately
83 dB in this mode, which is still greater than the SNR of AM radio.
