a. Edge-Sensitive Trigger Condition. The minimum pulse width (tILIH) is either 125 ns (fOP = 2.1 MHz)
or 250 ns (fOP = 1 MHz). The period tILIL should not be less than the number of tCYC cycles it takes to
execute the interrupt service routine plus 19 tCYC cycles.
b. Level-Sensitive Trigger Condition. If after servicing an interrupt the IRQ remains low, the
next interrupt is recognized.
