NAME

       srec_ti_tagged_16 - Texas Instruments Tagged (SDSMAC 320) file format

DESCRIPTION

       This  format is also known as the TITagged or Texas Instruments SDSMAC
       (320) format.

       This format allows binary files to be uploaded and  downloaded  between
       two  computer  systems,  typically between a computer system (such as a
       PC, Macintosh, or workstation) and an emulator or evaluation board  for
       16‐bit microcontrollers and microprocessors.

   The Lines
       Unlike  many  other  object  formats,  the  lines  themselves  are  not
       especially significant.  The format  consits  of  a  number  of  tagged
       fields, and lines are composed of a series of these fields.

                          Tag   Description
                          ---------------------------------
                          *     Data byte.
                          :     End of file.
                          0     File header (optional).
                          7     Checksum.
                          8     Dummy  checksum (ignored).
                          9     Word Address.
                          B     Data word.
                          F     End of data record.
                          K     Program         identifier
                                (optional).

   Data Byte
                                     +--+---+---+
                                     |B | n | n |
       One byte of data.  The nn is 8‐bit-big‐endian hexadecimal.

   End of File
                                     +--+------+
                                     |: | CRLF |
       The end of data is indicated by-this-tag.  The end of line sequence (LF
       on Unix systems, CRLF on PCs) follows this tag.

   File Header
                               +--+--------+----------+
                               |0 | length | filename |
       The optional start‐of‐file-record-begins-with-a+tag character (’0’) and
       a 12‐character file header. The first four characters are the count (in
       hex) of the 16‐bit data word values (B)  which  follow,  not  including
       data byte values (*). The remaining file header characters are the name
       of the file and may be any ASCII characters, blank padded.

   Checksum
                                 +--+---+---+---+---+
                                 |7 | n | n | n | n |
       The checksum is the 2s complement+sum+of-+the+ 8‐bit  ASCII  values  of
       characters,  beginning with the first tag character and ending with the
       checksum tag character (7).  The nnnn is 16‐bit big‐endian hexadecimal.

   Dummy Checksum
                                 +--+---+---+---+---+
                                 |8 | n | n | n | n |
       The  checksum  is  the  2s+-complement-sum-of+the 8‐bit ASCII values of
       characters, beginning with the first tag character and ending with  the
       checksum tag character (8).  The nnnn is 16‐bit big‐endian hexadecimal.

   Address
                                 +--+---+---+---+---+
                                 |9 | n | n | n | n |
       Addresses may be given for+any-data-byte,+but+none is  mandatory.   The
       file begins at 0000 if no address is given before the first data field.
       The nnnn is 16‐bit big‐endian hexadecimal.

   Data Word
                                 +--+---+---+---+---+
                                 |B | a | a | b | b |
       Two  bytes  of  data.   The--aa--and-+bb-+are+ each  8‐bit   big‐endian
       hexadecimal.

   End of Record
                                     +--+------+
                                     |F | CRLF |
       The  end  of line sequence (LF+on+Unix-systems, CRLF on PCs) is escaped
       using this tag.  The checksum is reset to zero at this point.

   Program Identifier
                             +--+---+---+---+---+------+
                             |K | n | n | n | n | text |
       The program identifier+can-contain-a-brief-description of the  program,
       or  can  be empty (i.e. the text portion is optional).  The nnnn length
       (hex) of the field includes the ‘K’, the length and the text; it is  at
       least 5.

   Size Multiplier
       In general, binary data will expand in sized by approximately 2.9 times
       when represented with this format.

EXAMPLE

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