When a uP or uC is exercising its POR cycle, what are the states of
the output pins? Floating, or held low, or what?

Particularly if it's recovering from a brown-out that caused POR to be
exerted.


You do mean _output_ pins, not general purpose I/O that might be
configured for either input or output -- right?


I guess I could be driven by an I/O pin. Is it possible to program
those as a "LOW" during POR?
