32 Bit Thinking.... # 3

What are level-triggered and edge-triggered interrupts?

-> A level-triggered interrupt is a class of interrupts where the presence of an unserviced interrupt is indicated by a high level (1), or low level (0), of the interrupt request line.

-> An edge-triggered interrupt is a class of interrupts that are signaled by a level transition on the interrupt line, either a falling edge (1 to 0) or a rising edge (0 to 1).

More answers for the question are welcome in the comments section.
Best regards.
