srec_ti_tagged(5)	      File Formats Manual	     srec_ti_tagged(5)

NAME
       srec_ti_tagged -	Texas Instruments Tagged (SDSMAC) file format

DESCRIPTION
       This format is also known as the	TI-Tagged or TI-SDSMAC 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
       microcontrollers	and microprocessors.

   The Lines
       Unlike many other object	formats, the lines themselves  are  not	 espe-
       cially  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	Address.
			  B	Data word.
			  F	End of data record.
			  K	Program	 identifier   (op-
				tional).

   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 byte
       count of	the file data.	The remaining 8	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 <i>a<i>a-and-<i>b<i>b-are-each-8-bit big-endian hexadeci-
       mal.

   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.
	      K000590080B4865B6C6CB6F2CB2057B6F72B6C64*0A7F648F
	      :
       and here	is another example from	the reference below
	      00050	   7FDD4F
