Description
Double Bit Fault Detect Interrupt Enable â 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 ï¬ag is set (see Section 15.3.2.8)
Single Bit Fault Detect Interrupt Enable â 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 ï¬ag is set (see Section 15.3.2.8)
1 An interrupt will be requested whenever the SFDIF ï¬ag is set (see Section 15.3.2.8)
15.3.2.7 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 15.6).
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.
