a. Edge-Sensitive Trigger Condition. The minimum pulse width (t
ILIH) is either 125 ns (fOP = 2.1 MHz)
or 250 ns (f
OP = 1 MHz). The period tILIL should not be less than the number of t
cyc 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.
