You can use the most of the GPIO pins as an interrupt source.

Have a look at our free SourceCode examples to see how you can use a GPIO interrupt.

If you would like to use another interrupt source, like timer interrupts, you don't need to do the GPIO specific part of the sample. You can use directly the IRQ number. For the PXAxxx modules you can find in them in the according technical reference manual. For The Colibri Txx modules please check this page.
