Assume for the moment that I want to read a chip (a 16F84A in this case) that I got from a miscellaneous source, and which I know has been programmed. If the programmer made it code-protected, will the ICD2 report that? Or will it just fail to read it with no message as to why? In other words, how does one tell if a chip is code protected or not? (This is just curiosity -- no evil motives whatsoever. :-) John -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
