Section 5 Interrupt Controller (INTC)
5.3.5
IRQRR is a 16-bit register that indicates interrupt requests from external input pins IRQ7 to IRQ0.
If edge detection is set for the IRQ7 to IRQ0 interrupts, writing 0 to the IRQ7F to IRQ0F bits after
reading IRQ7F to IRQ0F = 1 cancels the retained interrupts.
IRQRR is initialized by a power-on reset.
