hi guys, i'm now working on mc9s12xep100 chip, there's a 32k D-Flash in global memory, addressed from 0x10_0000 to 0x10_7FFF. I want now write data to the D-Flash through the EPAGE Register. Should i first partition D-Flash, erase sectors and then write to buffer RAM EEE? The data written to buffer RAM will be backed up to D-Flash?

By the way, i can only read the FSTAT Register but not write it, so i can't start command write sequence and neither launch command. Is anywhere else another FSTAT that can be written? Can anybody help? Thx a lot!
