DESCRIPTION

	API for target-specific implementation.
	
	Register numbers for MPC505 and MPC509.
	
	These register blocks are accessed via the kDSReadRegisters and
	kDSWriteRegisters messages.  The register number for a specific
	register is determined by its corresponding element number in these
	structures.  The register data in the messages must conform to
	the structures defined here in big-endian format.
	
VERSION
	
	CWDS 1.0

HISTORY
	
	97 FEB 28 LLY	Created.
	97 MAY 20 LLY	Removed register enumeration
	97 MAY 27 SCM   Reorganized registers according to new message
					format.
	97 JUN 10 SCM	Made some changes to the M821-specific registers.

//	*****************  Version 5  *****************
//	User: Smoore       Date: 9/22/98    Time: 11:03a
//	Updated in $/Embedded/MetroTRK/Processor/ppc/Export
//	Moved 5xx FP registers into the FP block.  Fixed FP block typedef.
//	
//	*****************  Version 4  *****************
//	User: Clayton      Date: 9/09/98    Time: 12:50p
//	Updated in $/Embedded/MetroTRK/Processor/ppc/Export

//	multiple reg.h files for different processors can be included in a
//	debugger plugin.

//	*****************  Version 3  *****************
//	User: Smoore       Date: 9/23/97    Time: 2:23p
//	Updated in $/Embedded/MetroTRK/Processor/ppc/M8xxExpt
//	Moved exceptionID from the start of the Extended1 block to the end.
//	
//	*****************  Version 1  *****************
//	User: Smoore       Date: 7/14/97    Time: 3:14p
//	Created in $/Embedded/MetroTRK/Processor/ppc/M821Expt
//	Reorganized CWDS and changed name back to TRK.

//	*****************  Version 1  *****************
//	User: Smoore       Date: 7/14/97    Time: 2:58p
//	Created in $/Embedded/TEMP/MetroTRK/Processor/ppc/M821Expt
//	Reorganized CWDS files and changed name back to TRK
//	
//	*****************  Version 1  *****************
//	User: Smoore       Date: 7/03/97    Time: 10:22a
//	Created in $/Embedded/MIPS2.0/new_TRK/Processors/PPC/M821/Export
