 globals.cxgate - definition of shared variables 
 -----------------------------------------------------
 These variables that are allocated in XGATE space but 
 can be refered by the HC12 too. 
               
Note: pointers defined in the shared RAM are unique to 
      the core and cannot be shared. Define in this 
      module all the variables that contain addresses 
      into the XGATE address space.
