I must admit I am looking forward to having the ability to reassign
peripherals to pins. To do some tests with the 18f25k22, I'm using an
existing board I made, but I have to tag on a bit as the particular pin I
need isn't routed to a connector. Oops.

What I don't understand is how they get 83 MIPS out of a 50 MHz part.


Agreed. The more complex arrangements of the fancier chips make that kind
of calculation a bit more complex?

Interesting. I am hoping to be doing serial comms at a higher rate, so ill
need to spend some time with the datasheet to work out multipliers.
