In the previous example we were able to make an LED blink with a 130ms period (65ms on, 65ms off). We were free to do other work as well while waiting for the interrupt to occur. However, we were simply polling (repeatedly checking) the interrupt flag status.

Webb9 juli 2024 · The interrupt code might look like the following code. But be aware that I'm assuming (for now) that there is only one interrupt that has been enabled. I'm making this assumption because (1) I have no information about other interrupts; and, (2) it would greatly complicate things.
