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.
Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be
assigned to this category. Any of the interrupt requests can be assigned to any of the
16 vectored IRQ slots, among which slot 0 has the highest priority and slot 15 has the
lowest.
Non-vectored IRQs have the lowest priority.
The VIC combines the requests from all the vectored and non-vectored IRQs to
produce the IRQ signal to the ARM processor. The IRQ service routine can start by
reading a register from the VIC and jumping there. If any of the vectored IRQs are
requesting, the VIC provides the address of the highest-priority requesting IRQs
service routine, otherwise it provides the address of a default routine that is shared by
all the non-vectored IRQs. The default routine can read another VIC register to see
what IRQs are active.

Interrupt sources
Table 4
lists the interrupt sources for each peripheral function. Each peripheral device
has one interrupt line connected to the Vectored Interrupt Controller, but may have
several internal interrupt flags. Individual interrupt flags may also represent more than
one interrupt source.
