ps: One nice thing about the P&E interface is that it comes with tools
that can program the 5554 internal flash. We used them just for this
task for a while - very useful in early development.

We eventually wrote our own flash programming app that we load into
ram with gdb, just because the Macraigor interface is so much faster.
