RE: PSELRESETx Register configuration

We have the same problem. nRF52832 and SoftDevice 112 are used. We use pin 21 in our project. Immediately after starting the application, we change the PSELRESET[0/1].CONNECT bit to "Disconnect". But after a reboot, this bit is reset.
There is no problem without SoftDevice.

Hi Santosh

You can set the PSELRESET registers before enabling the SoftDevice, yes. As I mentioned in the other case you simply have to set the CONFIG_GPIO_AS_PINRESET define in your project to have the PSELRESET registers configured correctly.

The SoftDevice will never access these registers, this is left up to the application.
