I'm switching from a 12F629 to a 16F676 to get more pins and trying to work out the differences in the pics. The following is supposed to use a falling edge Port Change Interupt on Pin 2. The program Blinks an LED at power up and is supposed to blink it 5 times at interupt. It blinks at power up but does not interupt. I had all of it worked out for the 629 and am sure there is something small I'm missing, but I can't seem to find it. Any help would be appriciated.
