@Brianbscho: I believe RK wanted to mention the nRF51 Series Reference Manual. You can find it here.

I would suggest you to have a look at the pin_change_int example project in our NRF51 SDK to know how to configure the registers.

Can you please tell me which manual are you talking about? If you could pass me the link, it'd be great. Thanks!

Look at chapter 15 in the manual on GPIOTE. That lets you configure either an individual pin (one of 4) for interrupt with the IN event which generates the GPOTE interrupt, or it lets you configure the PORT event for multiple pins, you then read the pins afterwards in the GPIOTE interrupt handler and decide what to do.

Note that depending on the version of the chip you have, the GPIOTE pin events (as opposed to the PORT event) keep the HF clock running and consume power. Rev 3 has that anomaly fixed.
