The Flash module can generate an interrupt when a Flash command operation has completed or when a

Flash command operation has detected an EEE error or an ECC fault.

The Flash module uses the CCIF ﬂag in combination with the CCIE interrupt enable bit to generate the

Flash command interrupt request. The Flash module uses the ERSEIF, PGMEIF, EPVIOLIF, ERSVIF1,

ERSVIF0, DFDIF and SFDIF ﬂags in combination with the ERSEIE, PGMEIE, EPVIOLIE, ERSVIE1,

ERSVIE0, DFDIE and SFDIE interrupt enable bits to generate the Flash error interrupt request. For a

detailed description of the register bits involved, refer to

Status Register
