Hi. This threw me at first!

For the ECIO40, pins C4 and C5 are used for USB comms to enable reprogramming. They are not shown on the chip view for this reason (though they are on the 18F4455 chip view). However, if for some reason you want to program once and never allow reprogramming, I'm told you could turn USB off and use those pins for I/O instead.

You should avoid using these pins if you have any option to do so.

Cheers,

Jonny
