6 srec_ti_tagged_16 - Texas Instruments Tagged (SDSMAC 320) file format
7
9 This format is also known as the TI‐Tagged or Texas Instruments SDSMAC
10 [4m(320) format.
11 This format allows binary files to be uploaded and downloaded between
13 two computer systems, typically between a computer system (such as a
14 PC, Macintosh, or workstation) and an emulator or evaluation board for
15 16‐bit microcontrollers and microprocessors.
16 The Lines
18 Unlike many other object formats, the lines themselves are not espe‐
19 cially significant. The format consits of a number of tagged fields,
20 and lines are composed of a series of these fields.
21 Tag Description
23 ─────────────────────────────────
24 * Data byte.
25 : End of file.
26 0 File header (optional).
27 7 Checksum.
28 8 Dummy checksum (ignored).
29 9 Word Address.
30 B Data word.
31 F End of data record.
32 K Program identifier
33 (optional).
34 Data Byte
36 ┌──┬───┬───┐
37 │B │ n │ n │
38 One byte of data. The nn is 8└‐─b─i┴t──b─i┴g─‐─e─n┘dian hexadecimal.
39 End of File
41 ┌──┬──────┐
42 │: │ CRLF │
43 The end of data is indicated b└y──t┴h─i─s──t─a─g┘. The end of line sequence (LF
44 on Unix systems, CRLF on PCs) follows this tag.
45 File Header
47 ┌──┬────────┬──────────┐
48 │0 │ length │ filename │
49 The optional start‐of‐fi└l─e─┴r─e─c─o─r─d──b─e┴g─i─n─s──w─i─t─h──a┘tag character ('0') and
50 a 12‐character file header. The first four characters are the count (in
51 hex) of the 16‐bit data word values (B) which follow, not including
52 data byte values (*). The remaining file header characters are the name
53 of the file and may be any ASCII characters, blank padded.
54 Checksum
56 ┌──┬───┬───┬───┬───┐
57 │7 │ n │ n │ n │ n │
58 The checksum is the 2s└──c┴o─m─p─l┴e─m─e─n┴t──s─u┴m──o─f┘the 8‐bit ASCII values of
59 characters, beginning with the first tag character and ending with the
60 checksum tag character (7). The nnnn is 16‐bit big‐endian hexadecimal.
61 Dummy Checksum
63 ┌──┬───┬───┬───┬───┐
64 │8 │ n │ n │ n │ n │
65 The checksum is the 2s└──c┴o─m─p─l┴e─m─e─n┴t──s─u┴m──o─f┘the 8‐bit ASCII values of
66 characters, beginning with the first tag character and ending with the
67 checksum tag character (8). The nnnn is 16‐bit big‐endian hexadecimal.
68 Address
70 ┌──┬───┬───┬───┬───┐
71 │9 │ n │ n │ n │ n │
72 Addresses may be given f└o─r─┴a─n─y─┴d─a─t─a┴─b─y─t┴e─,──b┘ut none is mandatory. The
73 file begins at 0000 if no address is given before the first data field.
74 The nnnn is 16‐bit big‐endian hexadecimal.
75 Data Word
77 ┌──┬───┬───┬───┬───┐
78 │B │ a │ a │ b │ b │
79 Two bytes of data. The └a─a─┴a─n─d─┴b─b──a┴r─e──e┴a─c─h─┘8‐bit big‐endian hexadeci‐
80 mal.
81 End of Record
83 ┌──┬──────┐
84 │F │ CRLF │
85 The end of line sequence (LF o└n──U┴n─i─x──s─y─s┘tems, CRLF on PCs) is escaped
86 using this tag. The checksum is reset to zero at this point.
87 Program Identifier
89 ┌──┬───┬───┬───┬───┬──────┐
90 │K │ n │ n │ n │ n │ text │
91 The program identifie└r──c┴a─n──c┴o─n─t─a┴i─n──a┴─b─r─i┴e─f──d─e─s─c┘ription of the program,
92 or can be empty (i.e. the text portion is optional). The nnnn length
93 (hex) of the field includes the `K', the length and the text; it is at
94 least 5.
95 Size Multiplier
97 In general, binary data will expand in sized by approximately 2.9 times
98 when represented with this format.

101 Here is an example TI‐Tagged file. It contains the data “Hello,
102 World[rq] to be loaded at address 0x0100.
