It didn't cause damage, but the pin did conduct.  About 25mA wendt through.
The port is fine and everything seems to work as usual.  This was too bad
though as I now need to clamp the FET-voltage before feeding it to the
comparator.  (I was trying to check for over-current without external
OP-AMPS...)
