      36            ; NOTES:
      37            ;   The program needs three memory sections to operate:
      38            ;   Actual location of these sections in the memory is defined in the
      39            ;   linker command file - *.cmd

      43            ;       PRG_data    Data buffer used to hold programming data
      44            ;
      45            ;   The size and location of each section  is user defined.  The
      46            ;   loader program will read the value of PRG_bufaddr and PRG_bufsize to
      47            ;   determine the location and size of the PRG_data section.
