nRF52832 P0.21/RESET pin

[Vala]

Hi,

How is the functionality of P0.21 in nRF52832? It is configured as RESET after turning on the device, right? Is there any way to change it in a way that that the chip starts working even when this pin is low?

Yes it's in the manual. Set PSELRESET registers and reset the chip. They are retained and will disable reset.

OK I thought CONFIG_GPIO_AS_PINRESET should be defined in the main source file. I am using GCC and I found two flags about CONFIG_GPIO_AS_PINRESET in the make file of the project. I commented both and now everything works as expected. Thanks RK.
