How to transfer the signal from one pin to another pin?

[B]

Hello! I am putting (with a wave generator) a square wave on pin 17 of the microcontroller, and I want that same wave to come out on pin 18. How do I do that? Do you have any specific commands? Thanks

Your pin connected to -> GPIOTE in event mode on toggles ->output connected to PPI channel -> output connected to another GPIOTE channel in task mode to toggle the pin-> which outputs the incoming pin to another pin with about two HFCLK cycles delay
