When an interrupt pin is both falling-edge and low-level triggered (MODE = 1), the interrupt remains set
until both of these events occur:
The vector fetch or software clear may occur before or after the interrupt pin returns to 1. 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 mask all external interrupt requests. A latched interrupt request
is not presented to the interrupt priority logic unless the IMASK bit is clear.
