PSELRESETx Register configuration

[santosh athuru]

We use soft device 132 on nRF52832. It looks like PSELRESET0/1 is being configured to pin 21 in Softdevice code, and we have our HW designed for the same.

How is it guaranteed that this configuration will not change in future as we don't have control on softdevice code. If our application configures PSELRESET0/1 prior to initializing softdevice will that be acceptable? is it guaranteed that the configuration done by user application will not be erased and re-configured by soft device?

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.
