> Olin, do you think 1 - is factory programming value, or is value at POR > (see page 25 of the programming spec, DS41244E)? POR is not relevant: power cycling a PIC does not affect the state of configuration bits (or other flash-stored bits). It is the 'after erase' that is relevant. > Finally, I don't think that PIC come with a known state of Configuration > Bits. Chips are sold in erased state. -- Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
