All assigned bits in the FERCNFG register are readable and writable.
28.3.2.7 Flash Status Register (FSTAT)
The FSTAT register reports the operational status of the Flash module.
CCIF, ACCERR, and FPVIOL bits are readable and writable, MGBUSY and MGSTAT bits are readable
but not writable, while remaining bits read 0 and are not writable.

Field Description
1
DFDIE
Double Bit Fault Detect Interrupt Enable — The DFDIE bit controls interrupt generation when a double bit fault
is detected during a Flash block read operation.
0 DFDIF interrupt disabled
1 An interrupt will be requested whenever the DFDIF flag is set (see Section 28.3.2.8)
0
SFDIE
Single Bit Fault Detect Interrupt Enable — The SFDIE bit controls interrupt generation when a single bit fault
is detected during a Flash block read operation.
0 SFDIF interrupt disabled whenever the SFDIF flag is set (see Section 28.3.2.8)
1 An interrupt will be requested whenever the SFDIF flag is set (see Section 28.3.2.8)
