You may be right about how it works on a PIC 18. I was thinking of the DE directive, which always put the EEPROM data into the low bits of an entire instruction word. This is also how the EEPROM data is written to the HEX file. That means that every other byte of EEPROM data in a HEX file for a PIC 18 is ignored and set to 0. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
