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 24.3.2.8)
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 24.3.2.8)
1 An interrupt will be requested whenever the SFDIF flag is set (see Section 24.3.2.8)
