.SH NAME
srec_ti_tagged \- Texas Instruments Tagged (SDSMAC) file format
.XX "srec_ti_tagged(5)" "Texas Instruments Tagged (SDSMAC) file format"
.SH DESCRIPTION
This format is also known as the \f[I]TI-Tagged\fP or \f[I]TI-SDSMAC\fP format.
.PP
.\" ------------------------------------------------------------------------
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.
.SS The Lines
Unlike many other object formats, the lines themselves are not especially
significant.  The format consits of a number of \fItagged\fP fields,
and lines are composed of a series of these fields.

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.
