Configuration of GPIO to wake up from System Off

[mikelugarte]

Hi,

I am working with a nrf51822 and I have seen that the way to wake up from System Off mode is by a GPIO interrupt. I wanted to know if it is needed to configure previously the GPIO pin to wake it up from System Off mode.

Sorry, now I used nrf_gpio_cfg_sense_input() but it keeps not working. I am not in debug mode, because I am using an online compiler.
