The PIC16F87/88 can do it; the PIC16F818/819 cannot. The PIC16F876A can do it, the PIC16F876 cannot. One clue is that chips that are supported in Debug mode by the ICD2 can almost all do it. --Bob -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
