Hello,
If you are using CodeWarrior for MCU (e.g. version 10.6.x) and Prcessor Expert project you can use IntEEPROM component to write to the internal EEPROM of this MCU. You can use one of the Set<type> methods of this IntEEPROM component (SetByte, SetWord or SetLong methods).
Best Regards,
Marek Neuzil
