// Filename: 	regdefs.h
// Project:	Zip CPU -- a small, lightweight, RISC CPU soft core
// Purpose:	This is a generic file that will need to be modified from one
//		board implementation of the ZIP CPU to another.  Specifically,
//	this file defines where items are on a WISHBONE bus.  In this case, the
//	Zip CPU debug addresses are found at 0x060 and 0x61--but they need not
//	be at those addresses in your application.  The Zip Debugger needs to
//	know these addresses in order to know what addresses to peek and poke
//	to control and access the Zip CPU.
