Hi,



I'm using the 18f8722. What I've noticed is that when I power up the
device and try to read Port F, I do not get anything back from pin 7
until after a few seconds of waiting. The circuit is fine, and the
port f pin 7 works fine on some hardware and this problem occurs on
other. There's some kind of pic hardware issue with the functionality
of using pins 5/6/7 on port f. I've done some testing and debugging
by moving lines to different pins but I've noticed that there's some
'correlation' between pins 5/6/7 on portf.



It all points towards a silicon issue possibly with the pic and has
yet to be reported by Microchip. There's no info on the Silicon
Errata datasheets.



Help greatly appreciated!



Regards,
