24.3.2.5
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.

ECC Error Register Index— The ECCRIX bits are used to select which word of the FECCR register array is
being read. See
Command Complete Interrupt Enable — The CCIE bit controls interrupt generation when a Flash command
has completed.
