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.
