 globals.h - declaration of shared data structures
 -----------------------------------------------------
   Copyright (c) Metrowerks, Basel, Switzerland
               All rights reserved
 -----------------------------------------------------
 These data structures are used by both, the XGATE
 and the HCS12 cores to exchange data. 
 
 Varaibles are defined in one of the these files:
 - globals.c  		  for HCS12 address space
 - globals.cxgate		for XGATE address space
 
 As long these variables do NOT contain addresses
 (pointers), they can be defined in either of these 
 two files. However, if a variable contains pointers,
 it has to be defined in the in the corresponding file.
               
Note: pointers defined in the shared RAM are unique to 
      the core and cannot be shared.
