I have set the following configuration for adding AT89C51RE2 to my device database but still the code size is limited to 64K while linking. An "Address Space Overflow" appears as soon as I exceed 64K. Could somebody point out the mistake/omission?

The link shows a "classic" 8051.
As Reinhard says, The AT89C51RE2 has specific on-chip banking hardware - it is described in the Datasheet.
