NAME

       srec_ti_tagged_16 - Texas Instruments Tagged (SDSMAC 320) file format

DESCRIPTION

       This format is also known as the TI-Tagged 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.
	      K000590080B4865B6C6CB6F2CB2057B6F72B6C64*0A7F641F
