External Interrupt (IRQ)
When set, the IMASK bit in INTSCR masks the IRQ interrupt request. A latched interrupt request is not
presented to the interrupt priority logic unless IMASK is clear.
A falling edge on the IRQ pin can latch an interrupt request into the IRQ latch. An IRQ vector fetch,
software clear, or reset clears the IRQ latch.
