____________________________________________________________________________

This directory contains C/C++ and Assembly headers containing all of
the registers in the NS486SXF.  These files are useful for developing
software for the NS486SXF, as they allow you do refer to registers
symbolically.

There are two header files:
  
  NS486REG.H    - C/C++ header file
  NS486REG.INC  - Assembly language include file

Please see the individual files for more information.  Because some
peripherals can be mapped in different locations (ECP, PCMCIA, UART),
you need to define a variable indicating which base address to use
before including the header file.  (This is not necessary if you do
not want to access the ECP, PCMCIA, or UART).  The header file comments
indicate how to do this.

These files will work directly in Microsoft, Borland, and Watcom compilers
and Assemblers.  For compilers and assemblers that use a different syntax,
you may need to modify the files.
