// The Ez-USB FX2 registers are defined here. We use FX2regs.h for register
// address allocation by using "#define ALLOCATE_EXTERN".
// When using "#define ALLOCATE_EXTERN", you get (for instance):
// xdata volatile BYTE OUT7BUF[64] _at_ 0x7B40;
// Such lines are created from FX2.h by using the preprocessor.
// Incidently, these lines will not generate any space in the resulting hex
// file; they just bind the symbols to the addresses for compilation.
// You just need to put "#define ALLOCATE_EXTERN" in your main program file;
// i.e. fw.c or a stand-alone C source file.
// Without "#define ALLOCATE_EXTERN", you just get the external reference:
// extern xdata volatile BYTE OUT7BUF[64] ;// 0x7B40;
// This uses the concatenation operator "##" to insert a comment "//"
// to cut off the end of the line, "_at_ 0x7B40;", which is not wanted.

This block of code redefines all of the _AT_ code above to do a direct replacement
of the constant values for the FX2 registers. The _AT_ section above will define
the registers so that they can be named by the debugger. This section tells
the assembler the constant values of the pointers so that DPTR optimization
can be performed.
