19.9.9 FIQ/IRQ Program Control Registers (FIRQPR[0:3])

The FIQ/IRQ program control registers determine whether a given interrupt request will be either FIQ or
IRQ. Figure 19-19,
NOTE: Channel 0 and 1 are FIQ only, not impacted by this register.

Value Description
FIQ/IRQ program control bits. These bits determine whether an interrupt request from a peripheral
is of type FIQ or IRQ. Bit FIRQPRx[127:2] corresponds to request channel[127:2].
0 Interrupt request is of IRQ type.
1 Interrupt request is of FIQ type.
3h Read only. Writes have no effect.
