HI,
We have ported our code for MC912DG128CCPVE to  MC9S12XEG128CAL. To test the ported code on Vector VT system, I need to change some data in EEPROM and replace it with my data. I have few questions related to that:

  1. Is there a way that would corrupt EEPROM configuration information ? If yes, how to erase then re-configure in Normal Single chip mode ?
  2. How firmware know that RAM buffer content has been completely transferred into emulated EEPROM ? 
  3. Does the characteristics of emulated EEPROM in MC9S12XEG128CAL are equivalent to those of MC912DG128CCPVE?I am using Code Warrior IDE V5.1. I have read many article related to this but I am not able to understand how to erase data in Normal Single chip mode and how to confirm transfer of data to Emulated EEPROM. I have Initialized the EEPROM using the FTM command sequence given in AN3743.
