In [[computing]], a '''level-triggered interrupt''' is a class of [[interrupt]]s that can be triggerd on either the rising edge or falling edge of the [[interrupt request]] line. An assertion of the line changes the it from low to high or high to low. This class of interrupts allows multiple devices to efficiently share the same interrupt line.

There are two ways in which an interrupt can be seen: Either as a single event or as a continuous condition.

Opposed toCompare [[edge triggered interrupt|edge triggered interrupts]], level triggered interrupts are seen as a continuous condition.
