Hmm, I put this in the same category as a warning stating "DO NOT
CRAWL ACROSS BROKEN GLASS."

What are the odds of "accidentally" sending a sync. word followed by a
few million '1' bits? I'm sure that someone must have done it, hence
the errata notice. I'm not sure this would be worth a $1M mask spin
to fix (unless there are more important issues as well).

You can damage lots of semi's by misprogramming them. Have the
outputs from two interface devices fight on a bus and just watch the
gladiatorial fun!
