Chapter 9 512 KByte Flash Module (S12XFTM512K3V1)
9.3.2.6
The FERCNFG register enables the Flash error interrupts for the FERSTAT flags.
All assigned bits in the FERCNFG register are readable and writable.

FECCR registers will not be updated during the Flash array read operation with FDFD set unless an actual
double bit fault is detected.
0 Flash array read operations will set the DFDIF flag in the FERSTAT register only if a double bit fault is detected

FECCR registers will not be updated during the Flash array read operation with FSFD set unless an actual single
bit fault is detected.
0 Flash array read operations will set the SFDIF flag in the FERSTAT register only if a single bit fault is detected
