tILIH
tILIL
Edge-sensitive trigger — The minimum tILIH is either 125ns (VDD=5V) or 250ns (VDD=3.3V). The minimum period tILIL
should not be less than the number of cycles it takes to execute the interrupt service routine plus 21 tCYC.
Edge and level sensitive trigger — If IRQ remains low after the initial interrupt is serviced, the MCU recognises the
interrupt until the IRQ line returns to a high level.
