Absolute ($FFFFF034)

Carsten Bager
Hi
W are using the compiler on an embedded Arm7 platform (no
operating system). Now we have run into this problem.
We want to define an absolute address, to a specific register.
It seems that, if the absolut address exceeding $FFFFF000 then we
get the error.



OK Compiling goes OK.
********************************************
Var
  VICDefVectAddr : Pointer Absolute $EFFFF034;    ß ß ß ß

Procedure UartInterrupt;
begin
end;

Begin
  VICDefVectAddr := @UartInterrupt;
End.

ERROR Compiling goes Wrong.
