What happens if two interrupts occur simultaneously?

Latest Updated:01/23/2014

Question:

What happens if two interrupts that have the same interrupt priority level occur simultaneously?

Answer:

When multiple interrupt requests of an identical level occur simultaneously, priority is given to the interrupt source that has the smaller vector number.

For details, please see the Interrupt Source Priority Register n (IPRn) section in the Interrupt Controller chapter.
