Preliminary data
6.4 Interrupt controller
The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and
categorizes them as FIQ, vectored 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.
