'Cant Program 12c508 Config bits'

       Im trying to program a 12c508 using MPASM (latest version) to assemble
the code, then burning the chip with a Parallax 16cxx programmer, using a
home-made adaptor, V4.2 firmware and SPEP v4.6.  The code programs ok but the
config never changes from its default state, no matter what settings I put in
SPEP.  The config information appears at the end of the hex file but I think
SPEP ignores it.  Does anyone have an idea why SPEP cant change the config
bits?

Because the rest of the code programs ok I dont think there is any problem with
the adaptor.

Thanks for any help,

Jerome Knapp

As a beginner i met the same problem. Try this solution:
- download SPEP 4.7
- MPASM produces the .hex file.
- load the .hex file in SPEP.
- change configuration as you want it.
- save the file as .obj file

next time you load the .obj file all setting appear to be  saved
