Sorry just to clarify I am required to use the PicF16887 not Pic16F877.
...

This cannot be a true statement. Microchip part numbers start with the family: "16" in this case, followed by a letter or two "F" in this case for "Flash Memory" followed by a particular device type "887" in this case. Mixing the three elements up does not change anything. So a PicF16887 and a Pic16F887 are just cyclic permutations of alphanumeric characters that reference exactly the same device.

Yes, this is true oddly in my first post I wrote Pic16K877 I believe when I meant PIC16F887. My fingers are letting me down my apologizes.
