/* Define the memory block start/length for the F2809  
   PAGE 0 will be used to organize program sections
   PAGE 1 will be used to organize data sections

   Notes: 
         Memory blocks on F2809 are uniform (ie same
         physical memory) in both PAGE 0 and PAGE 1.  
         That is the same memory region should not be
         defined for both PAGE 0 and PAGE 1.
         Doing so will result in corruption of program 
         and/or data. 
         
         L0/L1 and H0 memory blocks are mirrored - that is
         they can be accessed in high memory or low memory.
         For simplicity only one instance is used in this
         linker file. 
         
         Contiguous SARAM memory blocks or flash sectors can be
         be combined if required to create a larger memory block.
