8.12.5.1 Interrupt Sources

The SECUMOD provides two interrupt lines, each connected to one of the internal sources of the interrupt controller. Using these interrupts requires the interrupt controller to be programmed first. Interrupt lines must not be used in Edge-sensitive mode.

The first interrupt line (SECURAM) is used to signal violations of backup memory access rights, or to signal end of erase (automatic or software erase).

The second interrupt line (SECUMOD) is shared by all the protection mechanisms except backup memories access right violations signaling, or end of erase (automatic or software erase) signaling. For details on interrupt lines, refer to the table "Peripheral Identifiers".
