RK sorry it was my fault, I hope that you will receive my apology. Next time I will be more careful.

so basically the problem isn't the thing you reported and the code isn't the code you used to do the testing. How about asking a proper question about the proper issue with the proper code because otherwise you're rather wasting everyone's time.

Sorry I did not mention that when I were testing nrf_gpio_pin_toggle() function was used.

What response did you expect since all you do is clear the pin

I tested pins with oscilloscope and I did not receive any respose. I think that pin 9, 10 and 11 are reserved.

Did you read the documentation on the function you are calling? It says quite clearly ..

__STATIC_INLINE void nrf_gpio_cfg_output(uint32_t pin_number);
@note  Sense capability on the pin is disabled, and input is disconnected from the buffer as the pins are configured as output.

If you want to read the pin then you need to connect the input buffer so using that macro to set up the pin won't help you. Use the full version of pin setup and connect the input buffer.
