64.4.1 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. Note that it is not recommended to use the interrupt lines in Edge-sensitive mode.

The first interrupt line (SECURAM ID) is dedicated to backup memories access right violations signaling, or end of erase (automatic or software erase) signaling.

The second interrupt line (SECUMOD ID) is shared by all the protection mechanisms.

See the Register Summary section for more information about interrupt acknowledgment.

The SECURAM and the SECUMOD interrupt lines are connected to the interrupt controller. The interrupt controller must be programmed before configuring the SECURAM or the SECUMOD.
