Hi, all.
I have been using the nRF51822 board, I am making a peripheral. The peripheral has been equipped with a sensor to multiple GPIO. (For example, sensor1 to P0.9 , sensor2 to P0.10 )
After the application has waking up the SYSTEM OFF mode, I want to get the PIN number of GPIO that was waking up the SYSTEM OFF mode. (wake-up by P0.9 , wake-up by P0.10) ※ Application has been returned from the SYSTEM OFF mode by the interruption of the GPIO.
How to get of interrupt factor(P0.9 or P0.10) after returning from the SYSTEM OFF mode?
