I believe the combination of the 887 datasheet and the documentation that =

came with your PICkit2 (assuming it is like the one I just purchased) have =

that info.
Have you tried the Microchip web site? They have a lot of info, including =

application notes, concerning ICSP.

Other posters have also suggested other sources for the information.
