Ok, so I see in the datasheet where it calls out the flash write edurance. What I don't know is what behavior I should expect at that point. Will it be verify errors during programming? Will it loose data after programming and succesful verification? Will it be intermittant, etc? (DSPIC 30F6015, byt the way) -Denny -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
