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.
1. The single bit fault and double bit fault flags are mutually exclusive for parity errors (an ECC fault occurrence can be either

indicated when both SFDIF and DFDIF flags are high.

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
was attempted on a Flash block that was under a Flash command operation.
writing a 1 to DFDIF. Writing a 0 to DFDIF has no effect on DFDIF.
0 No double bit fault detected
1 Double bit fault detected or an invalid Flash array read operation attempted
Single Bit Fault Detect Interrupt Flag — With the IGNSF bit in the FCNFG register clear, the SFDIF flag
indicates that a single bit fault was detected in the stored parity and data bits during a Flash array read operation
or that a Flash array read operation was attempted on a Flash block that was under a Flash command operation.
The SFDIF flag is cleared by writing a 1 to SFDIF. Writing a 0 to SFDIF has no effect on SFDIF.
0 No single bit fault detected
1 Single bit fault detected and corrected or an invalid Flash array read operation attempted
