Clarification of brown out reset or not?

[dgerman]

Can someone please clarify . nRF52832_V1.3

These 2 sections seem to be contradictory.

18.4.1 Power-fail comparator
The power-fail comparator (POF) can provide the CPU with an early warning of impending power failure.
It will not reset the system, but give the CPU time to prepare for an orderly power-down.

If the POF is enabled and the supply voltage falls below VPOF, the POFWARN event will be generated.

____

18.6.6 Brown-out reset
The brown-out reset generator puts the system in reset state if the supply voltage drops below the brownout reset (BOR) threshold.

There is no contradiction. That is why one is called POF and one is called brown out reset. POF can be used to gracefully shutdown the system since it generates a system event that will be serviced. Some people also use it as a low battery indicator. On top of that if system voltage drops below 1.7(i think ?) for nRF 52, the system will go into reset.
