Load the flasher program into RAM, and run the upgrade out of RAM using
polled serial I/O to avoid annoyance and complications with interrupt tables.

If you can't find a pin that is documented to have this behavior, then that
connection point on the core is probably tied internally and not brought
out to a pin.
