In this case the data sheets are the ones available in pdf on hh:
http://www.handhelds.org/platforms/hp/ipaq-h5xxx/

13-gpio.pdf and 14-int.pdf are the ones with the information you are

The code I am prattling on about is in h5400_asic_io.c. See

and 18 layout these registers. But...

If your software debouncing works, use it.
