For easy access to the 8051 special function register and interrupt
addresses, <NOBR>ASEM-51</NOBR> has a number of predefined (built-in) DATA,
BIT and CODE symbols.<BR>
These predefined symbols can be switched off with the $NOMOD51 control.
For detailed information on symbols and addresses refer to
<A HREF="append_c.htm">Appendix C</A>.
For identification of the assembler and its version number, the following
NUMBER type symbols are predefined:
<BLOCKQUOTE>
??ASEM_51 = 8051H <NOBR>ASEM-51</NOBR><BR>
??VERSION = 0130H <NOBR>version 1.3</NOBR>
</BLOCKQUOTE>
These two symbols can not be switched off!
