D RESTRICTIONS FOR THE 80751 AND THE 80752

The 8xC751 and 8xC752 processors do not allow usage of the LCALL/LJMP and MOVX instructions. The following actions should be taken when you are not using EDE:

With EDE, the assembler and compiler are automatically called with the controls and option mentioned above when you select the 8xC751 or 8xC752 processor.

The C library is delivered as c751s.lib. It contains no floating point functions, because floating point needs xdat memory. It also contains no run-time routines using pdat or xdat (not possible on this type of processor).

The floating point library is not supported due to the very limited resources of the 751 (only 64 bytes of RAM).
