ECC Error Register Indexâ The ECCRIX bits are used to select which word of the FECCR register array is
ECCRIX[2:0] being read. See Section 24.3.2.13, âFlash ECC Error Results Register (FECCR),â for more details.
24.3.2.5 Flash Conï¬guration Register (FCNFG)
The FCNFG register enables the Flash command complete interrupt and forces ECC faults on Flash array
read access from the CPU or XGATE.

Description
Command Complete Interrupt Enable â The CCIE bit controls interrupt generation when a Flash command
has completed.
0 Command complete interrupt disabled
1 An interrupt will be requested whenever the CCIF ï¬ag in the FSTAT register is set (see Section 24.3.2.7)
Ignore Single Bit Fault â The IGNSF controls single bit fault reporting in the FERSTAT register (see
Section 24.3.2.8).
0 All single bit faults detected during array reads are reported
1 Single bit faults detected during array reads are not reported and the single bit fault interrupt will not be
generated
