3.3 Interrupts – Component 2

Purpose of the test: Verify that interrupts occur and are handled at the expected rate.

Most applications rely on interrupts for their operation and it is therefore important to verify that these occur at the time they are expected and are handled accordingly.

Acceptable measures for Fault detection include functional testing and/or time-slot monitoring of the interrupts. Time-slot monitoring is recommended since this will help detect faulty operation once the appliance is in use. Any interrupt testing will also indirectly test the interrupt controller.
