Product data sheet
6.5 Interrupt controller
The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and
categorizes them as Fast Interrupt Request (FIQ), vectored Interrupt Request (IRQ), and
non-vectored IRQ as defined by programmable settings. The programmable assignment
scheme means that priorities of interrupts from the various peripherals can be dynamically
assigned and adjusted.
Fast Interrupt reQuest (FIQ) has the highest priority. If more than one request is assigned
to FIQ, the VIC combines the requests to produce the FIQ signal to the ARM processor.
The fastest possible FIQ latency is achieved when only one request is classified as FIQ,
because then the FIQ service routine can simply start dealing with that device. But if more
than one request is assigned to the FIQ class, the FIQ service routine can read a word
from the VIC that identifies which FIQ source(s) is (are) requesting an interrupt.
