To whom it ma concern,
we observed Unkwon Resets after Long runtime ; Several Hours.
We use the NRF52840.
After the reset bit 1 in RESETREAS is detected .
BUT investigation with a scope shows no valid change for the physical reset pin.
WE do noticed some changes in the VDD voltage but within valid working range.
I stepped over the description of the NRF52832:

Is it possible this is valid for the NRF52840 as well?
AND this behavior sets bit 1 in RESETREAS ?
