9S12 EEPROM programming questions

I think I have routines that can program the EEPROM on an MC9S12XDT512CAA.  I am using the DEMO9S12XDT512 to prototype with.  However when I load my program the True-Time Simulator and Realtime Debugger shows the EEPROM at 0x0800 to be erased.
 
Is the EEPROM being erased by the loader or are my routines not actually working?  Can this erasing be turned off so I can be sure my programming is working?
 
Thanks :smileyhappy:
