Thank you @MaBe for that snippet as it shall come in handy.

I am a bit curious how one gets from the Nordic board silkscreen values:

https://infocenter.nordicsemi.com/topic/ug_nrf52840_dongle/UG/nrf52840_Dongle/Images/nRF52840_dongle_front.svg

to the output that your JS snippet provides.

I've located the jspin.c file along with the specific nrf_gpio.h but just haven't stumbled across the method that is used to determine the offsets for the above image. I'm sure I'll eventually locate the source, but in the mean time your JS snippet should provide the needed reference.
