IRQ FIQ

The AIC classifies the interrupt into FIQ and IRQ. This register indicates whether the asserted interrupt is
FIQ or IRQ. If both IRQ and FIQ are equal to 0, it means there is no interrupt occurred.

IRQ [1]: Interrupt Request

0 = nIRQ line is inactive.

1 = nIRQ line is active.

FIQ [0]: Fast Interrupt Request

0 = nFIQ line is inactive.

1 = nFIQ line is active
