I faced a problem while working with the EEE of MC9S12XEG128. The error happens rarely but it will set the EPVIOL and ACCERR flags, and no further write to the EEE NVM takes effect. I mean the EEE buffer RAM acts as an ordinary RAM and the data written to it will not be transferred to the EEE NVM (Dflash EEE partition). Does anybody know the reason and what's the solution? I really appreciate your help.
