EEE Error Type 1 Interrupt Enable — The ERSVIE1 bit controls interrupt generation when a change state error
is detected during an EEE operation.
0 ERSVIF1 interrupt disabled
1 An interrupt will be requested whenever the ERSVIF1 flag is set (see Section 24.3.2.8)
EEE Error Type 0 Interrupt Enable — The ERSVIE0 bit controls interrupt generation when a sector format error
is detected during an EEE operation.
0 ERSVIF0 interrupt disabled
1 An interrupt will be requested whenever the ERSVIF0 flag is set (see Section 24.3.2.8)
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)

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.
