What does PWRT represent? I don't recognize the acronym but I became
familiar with it when I updated to the latest MPLab and I kept getting a
message that PWRT conflicts with config bits for BOD.
This happened whenever I tried to write to a 16F876 so I deduced that BOD
was brown out detect and I was able to write once I turned off BOD,
otherwise I tried flashing the chip with a program that had a PWRT mention
in the config line I think, and BOD was allowed to stay on.

So what does all that mean?
