Sorry for the misunderstanding. However, if the nRF52832 is held in reset mode, the pin configuration will be the same as in my answer above. The GPIO pins will be configured as input pins as soon as the device enters reset mode.

Thank you very much for your help. What I really want to know is "During reset" not "after reset". During HW reset pin is LOW, IO pins are output? or input? If output, level high? or low? I need your help.

Hi roger.k!

As we can see from the nRF52 product specification, the GPIO pins will be set as input after the reset.

Best regards
Joakim
