interrupt request
(IRQ) The name of an input found on many processors which causes the processor
to suspend normal instruction execution temporarily and to start executing an
interrupt handler routine. Such an input may be either "level sensitive" - the
interrupt condition will persist as long as the input is active or "edge
triggered" - an interrupt is signalled by a low-to-high or high-to-low
transition on the input. Some processors have several interrupt request inputs
allowing different priority interrupts.
