There's a document in the docs directory of the git repo explaining
that: https://github.com/entropia/tip-toi-reveng/blob/master/docs/The_Code.pdf

Please note: the number you get out of there is not the number the pen
reports, there's a mapping table inside tttool for that (should be
https://github.com/entropia/tip-toi-reveng/blob/master/src/KnownCodes.hs).
