The FERSTAT register reflects the error status of internal Flash operations.
All flags in the FERSTAT register are readable and only writable to clear the flag.

single fault or double fault but never both). A simultaneous access collision (Flash array read operation returning invalid data
attempted while command running) is indicated when both SFDIF and DFDIF flags are high.
There is a one cycle delay in storing the ECC DFDIF and SFDIF fault flags in this register. At least one NOP is required after
a flash memory read before checking FERSTAT for the occurrence of ECC errors.
The single bit fault and double bit fault flags are mutually exclusive for parity errors (an ECC fault occurrence can be either

Double Bit Fault Detect Interrupt Flag — The setting of the DFDIF flag indicates that a double bit fault was
detected in the stored parity and data bits during a Flash array read operation or that a Flash array read operation
returning invalid data was attempted on a Flash block that was under a Flash command operation.

Single Bit Fault Detect Interrupt Flag — With the IGNSF bit in the FCNFG register clear, the SFDIF flag
