19.3.2.5
The FCNFG register enables the Flash command complete interrupt and forces ECC faults on Flash array
read access from the CPU or XGATE.
CCIE, IGNSF, FDFD, and FSFD bits are readable and writable while remaining bits read 0 and are not
writable.
19.3.2.6
The FERCNFG register enables the Flash error interrupts for the FERSTAT flags.
