Vectored Interrupt Controller
EP93xx User’s Guide
6.1.1 Interrupt Priority
A FIQ interrupt has the highest priority (because the ARM9 core will always treat FIQ as
higher priority), followed by vectored interrupt 0 to vectored interrupt 15. Non-vectored IRQ
interrupts have the lowest priority. Any of the non-vectored Interrupts can be either FIQ or
IRQ (the interrupt type is determined by programming the appropriate register,
