I´m looking for a routine which allows me to write in flash and use it like an EEPROM in a MC9s08AW60. I only want to write some bytes like date, serial number and things like that. Is there any AN or something like that where shows how to do that?.
See the old Metrowerks technical note, TN015 "Mixing Assembly and ANSCI C in an Application". I don't think it's on Freescale's server anymore, so I've attached it for you.
