if C, what is your compiler? some of them integrate EEPROM data management =
(as e.g. cosmic with @eeprom qualifier), so you don't need extra code effor=
t (excepted if you really want to optimize operations).

You can use processor expert, which is an add on to codewarrior, to make stub
routines to handle eeprom writing.
