Some serial EEPROMs, at least old Xicor ones, erased to 0xFF but as shipped from the factory they contained a "checker board" pattern. Looked more like junk when doing a read, because the rows and columns were physically different than what you would logically expect. I asked the Xicro factory about that, and they set it was to expedite their test times. Ever since I've never made the assumption a new factory part comes in the erased state, unless that is explicitly mentioned in the data sheet, of any programmable part. _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
