Interrupt controller defined bits

The FIQ interrupt controller is one bit wide. It is located on bit 0.

Table 4-11 gives details of the interrupt sources associated with bits 1 to 5 in the IRQ

interrupt controller registers. You can use bit 0 for a duplicate FIQ input.

NoteNote

Timer 1 and Timer 2 can be configured to use different bits in the IRQ controller

registers, see Timer on page 2-34.
