      14            ;   unsigned   PRG_devsize      Size of programmable device
      15            ;   unsigned * PRG_paddr        First programming address
      16            ;   unsigned   PRG_page         Programming page
      17            ;   unsigned   PRG_length       Length of programming data

      21            ;   PRG_init                    Initialize system for programming
      22            ;   PRG_program                 Program a block

      30            ;   The global and public function symbol values must be available in the
      31            ;   COFF file for the loader to work properly. The functions are not
      32            ;   intended to be called by another program.

      34            ; NOTES:
      35            ;   The program needs three memory sections to operate:
      36            ;   Actual location of these sections in the memory is defined in the
      37            ;   linker command file - *.cmd
      38            ;
      39            ;       PRG_text    Executable section for this program
      40            ;       PRG_parms   Variable section for this program
      41            ;       PRG_data    Data buffer used to hold programming data
      42            ;
      43            ;   The size and location of each section  is user defined.  The
      44            ;   loader program will read the value of PRG_bufaddr and PRG_bufsize to
      45            ;   determine the location and size of the PRG_data section.
