I just had a client call with a problem programming a 16F873 processor using ICSP. He finally got the chip to erase, program, and verify except for the configuration word. Are there any hidden special gotchas for that sequence that I may be missing. He seems to be following the flowchart for the proper programming sequence as shown in the flash memory programming PDF file from the web site. Thanks Larry G.
