5 ; DESCRIPTION:
6 ; Flash Programmer control module with flash algorithms -C
7 ; called by the JTAG loader, PRG2xxw.exe
8 ; Uses the on-chip B0/1 ram for algorithms and flash data buffer
9 ;
10 ; GLOBALS:
11 ;
12 ; unsigned PRG_options Option selection word.
13 ;
14 ; unsigned * PRG_bufaddr Address of buffer for flash/program data
15 ; unsigned PRG_bufsize Size of program data buffer
16 ; unsigned PRG_devsize Size of programmable device
17 ; unsigned * PRG_paddr First programming address
18 ; unsigned PRG_page Programming page
19 ; unsigned PRG_length Length of programming data
20 ; unsigned PRG_status Status of programming functions
21 ;
22 ; PUBLIC FUNCTIONS:
23 ; PRG_init Initialize system for programming
24 ; PRG_program Program a block
25 ; PRG_erase Erase a programmable device
26 ; PRG_verify Verify a block
27 ;
28 ; PRIVIATE FUNCTIONS:
29 ; None
30 ;
31 ; USAGE/LIMITATIONS
32 ; The global and public function symbol values must be available in the
33 ; COFF file for the loader to work properly. The functions are not
34 ; intended to be called by another program.
35 ;
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
40 ;
41 ; PRG_text Executable section for this program
42 ; PRG_parms Variable section for this program
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.
48 ;
49 ; JTAG loader command file format
50 ; PRG2xxw -[options] c2xxprog.out Flashcode.out
51 ; <JTAG loader) <Flash algorithm> <COFF file to be flashed>

56 ; Modified for F2xx devices: Sam Saba, TI Houston 12/24/96
57 ; Added appropriate init code for PLL & WD disable - 15 Jan 97 (DAF)
58 ; Added Conditional assembly for PLL Mult factor selection - 26 Feb 97 (DAF)
59 ; Modified for: Compatibility with -s option and new algorithms.
