////////////////////////////////////////////////////////////////////////////////

// Filename: 	regdefs.cpp
//
// Project:	CMod S6 System on a Chip, ZipCPU demonstration project
//
// Purpose:	To give human readable names to the various registers available
//		internal to the processor on the wishbone bus.  This file is
//	primarily used for name to number translation within wbregs.cpp.
//	All names for a given register are equivalent, save only that the
//	register will always be identified by its first name in any output.
