[quote user=""]When you press the RESET button of the PCA10056, is it possible to add code before it does a reset?[/quote]

No, it's hardware wired full reset.

[quote user=""]Does pressing the RESET button allow you to do a full reset and get out of any crash? Or the level of the interrupt is not low enough compared to other interrupts?[/quote]

It will always do a hard reset.

[quote user=""]What does a power OFF - power ON do in addition to a reset via the button?[/quote]

Please check:

Also note that you can check the reset source by reading the RESETREAS register in the beginning of main(), make sure to clear the register after reading:

Have you checked the nRF52840 Product Specification for details of the Reset pin behaviour?
