Oh, I didn't notice that either.  I just saw 18Fxx20 and assumed it
included the 18F1320.

No, you're not.  I discovered a bug that matches this description on an
18F1320 and it was confirmed by Microchip.  So far I have assumed these
goto 20MHz, but that was only my testing a few parts on my code at room
temperature.  Until a difinitive errata is released for the 18F1320, I
would assume they have the same problem.  I'm staying away from
18F1320/1220 above 4MHz until this issue is properly clarified by
Microchip.
