PIC16F873 S4 Won't Erase

Once the code protection is set on the PIC16X873 the normal 'chip erase' command used by the S4 does not seem to work. Microchip seem to recommend a different erase algorithm if code protect is set - Is this being implemented by the S4? (I am using the PIC lib 2.33)

Hi,
Could you confirm the part number of the device you are using, is it a 16F87x device?

Yes the device was a PIC16F873 - Standard narrow plastic dip version. I used a 1:1 adapter as the pins spacing on the S4 ZIF socket are spaced too wide.

Hi,
Ok, I am currently looking into this and will post here as soon as I have anything.
