// The Ez-USB registers are defined here. There used to be 3 files containing
// this information: ezregs.h (external refs), ezregs.c (bound reg names to an 
// explicit address in ezusb.lib), and ezregs.inc (included in assembly files).
// We now use ezregs.h for register address allocation instead of ezregs.c by  
// using "#define ALLOCATE_EXTERN". The file ezregs.c now just includes ezregs.h.
// When using "#define ALLOCATE_EXTERN", you get: 
// xdata volatile BYTE OUT7BUF[64]      _at_    0x7B40;
// Such lines used to be in ezregs.c, but now are created from ezregs.h by using
// the preprocessor. The definitions in ezregs.c were redundant.
// Incidently, these lines will not generate any space in the resulting hex 
// file; they just bind the symbols to the addresses for compilation. 
// Since the file ezregs.c is still used in the library build, you normally
// just need to use #include "ezregs.h" in your files (i.e. fw.c).
// If you want to generate your own (non-frameworks based) C example, then you 
// just need to put "#define ALLOCATE_EXTERN" in your main program file; 
// i.e. fw.c or a stand-alone C source file. Any time you link with ezusb.lib,
// it will not be necessary to "#define ALLOCATE_EXTERN".
// 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.
// If you modify the register definitions below, please regenerate the file 
// "ezregs.inc" which uses the same basic information, but which could not be 
// derived automatically from this one source file using the preprocessor.
