Description
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 24.3.2.8)
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 24.3.2.8)
1 An interrupt will be requested whenever the SFDIF flag is set (see Section 24.3.2.8)
24.3.2.7 Flash Status Register (FSTAT)
The FSTAT register reports the operational status of the Flash module.

1 _{Reset value can deviate from the value shown if a double bit fault is detected during the reset sequence (see Section 24.6).}
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.
