/* Define the memory block start/length for the F2812  
   PAGE 0 will be used to organize program sections
   PAGE 1 will be used to organize data sections

   Notes: 
         Memory blocks on F2812 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.
