WebA Cortex-A9 processor enters IRQ mode in response to receiving an IRQ signal from the GIC. Before such interrupts can be used, software code has to perform a number of steps: 1.Ensure that IRQ interrupts are disabled in the A9 processor, by setting the IRQ disable bit in the CPSR to 1. 2.Conﬁgure the GIC.
