Interrupt Controller (CF1_INTC)
10.3.1
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).
