Preliminary data sheet
7.4 Interrupt controller
The ARM processor core has two interrupt inputs called Interrupt Request (IRQ) and Fast
Interrupt Request (FIQ). The VIC takes 32 interrupt request inputs which can be
programmed as FIQ or vectored IRQ types. The programmable assignment scheme
means that priorities of interrupts from the various peripherals can be dynamically
assigned and adjusted.
FIQs have the highest priority. If more than one request is assigned to FIQ, the VIC ORs
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
