Upon clearing CCIF to launch the Erase EEPROM Sector command, the Memory Controller will erase the
selected Flash sector and verify that it is erased. The CCIF flag will set after the Erase EEPROM Sector
operation has completed.

The Flash module can generate an interrupt when a Flash command operation has completed or when a
Flash command operation has detected an ECC fault.
