Let me first introduce myself.
I am Sten, a mechanical engineer with an interest in programming. I am working on the disassembly of a Ducati 998 ECU to be able to change part of the program.
The ECU is a Magneti Marelli using a MC68376 processor. I've found much help in using easy68k to understand the code, but I switched to IDA at some point because there just are so many bytes to analyse.

I used the processor description (pdf) to find specific memory allocation like $FFF100, $FFF080 etc.
At the moment I'm stuck because I can not understand some references in the code.
The Eeprom-file is 3FFFF bytes long, but as you can see there are some references to $44048, $44001 locations.
Now this would be outside of the Eeprom space, so could anybody help me what this reference means.
Thank you for all the help!
