Memory Map and Registers
15.4.3 Force Interrupt Register (INTC_FRC)
The INTC_FRC register allows software to generate a unique interrupt for each possible
level at the lowest priority within the level for functional or debug purposes. These
interrupts may be self-scheduled by setting one or more of the bits in the INTC_FRC
register. In some cases, the handling of a normal interrupt request may cause critical
processing by the service routine along with the scheduling (using the INTC_FRC
register) of a lower priority level interrupt request to be processed at a later time for less-
critical task handling.
The INTC_FRC register may be modified directly using a read-modify-write sequence or
through a simple write operation using the set/clear force interrupt registers
(INTC_SFRC, INTC_CFRC).
