Thanks MartinBL !!!

I've attached external LC filters with both DC/DC converters. I will be activating DC/DC in place of LDO as they are more efficient. To enable them I would be modifying registers

NRF_POWER->DCDCEN &

NRF_POWER->DCDCEN0

Further, In high power mode, I will be selecting VDD by

NRF_UICR->REGOUT0

I hope these configurations will not cause any issue in proper functioning.

Hi,

You can use the debug out port on your PDK: Debug output.

There is no software or configuration required to do this. It should work out of the box. Just make sure you have access to the GND, VDD, SWDIO, SWDCLK pins on your custom PCB.
