GPIOTE input event – how to change polarity at runtime

[samsam]

Let say during the normal program flow I want to change often the edge direction which will trigger the event: rising edge, none, falling edge, none … Can I work direct with registers for CONFIG[n].POLARITY or do I need on every change to call nrf*_gpiote_in_init() . Any example ?

 Thanks

If I were you, I would not mix driver (which remembers states) functionality and trying to access those registers directly. This would confuse the driver very much and I am pretty sure that the outcome is unpredictable.
