ASSEMBLER DIRECTIVES->Assembly Options->MOD51/NOMOD51

MOD51/NOMOD51                            Predefine Symbols


By default, a number of symbols are predefined when the cross assembler starts.  The precise symbols predefined depends on whether or not the 8052 directive has been used.  The NOMOD51 directive can be used to prevent any symbols being predefined by the cross assembler.

The MOD51 directive is provided to ensure compatibility with some earlier Intel assemblers.

MOD51 - predefine 8051 or 8052 symbols

NOMOD51 - do not predefine 8051 or 8052 symbols

Default - predefine 8051 or 8052 symbols

These directives can only be used in the command line.
