In which interrupt, the trigger is dependent on the logic level?(a) edge triggered(b) level-triggered(c) software interrupt(d) nmiThe question was asked by my college professor while I was bunking the class.I want to ask this question from The mechanism of Interrupts in chapter Interrupts and Exceptions of Embedded Systems

Answer»

The correct CHOICE is (b) LEVEL-triggered

For explanation I would say: In the level-triggered interrupt, the trigger is completely dependent on the logic level. The processors may require the level to be in a certain clock width so that the shorter pulses which are shorter than the minimum PULSE width are IGNORED.
