External Interrupt (IRQ)
The vector fetch or software clear may occur before or after the interrupt pin returns to a high level. As
long as the pin is low, the interrupt request remains pending. A reset will clear the latch and the MODE
control bit, thereby clearing the interrupt even if the pin stays low.
When set, the IMASK bit in the INTSCR masks all external interrupt requests. A latched interrupt request
is not presented to the interrupt priority logic unless the IMASK bit is clear.
