I want to know the configuration of Nordic's GPIO pins. I only want to use one callback function, but due to the many buttons on my mouse device, it is not possible to configure an interrupt callback function for all of them. It is too troublesome. How can I identify different pins, such as p1.1 and p2.1? Although I have seen that callback functions can be passed back to ports, I have to use a for loop to traverse the entire number of ports and pin_mask devices every time. I feel it is too troublesome. Is there a better way
