III.9 Predefined Symbols

For easy access to the 8051 special function register and interrupt addresses, ASEM-51 has a number of predefined (built-in) DATA, BIT and CODE symbols.
These predefined symbols can be switched off with the $NOMOD51 control. For detailed information on symbols and addresses refer to Appendix C. For identification of the assembler and its version number, the following NUMBER type symbols are predefined:

??ASEM_51   =   8051H          ASEM-51
??VERSION   =   0130H          version 1.3
