NAME

       srec_tektronix - Tektronix hexadecimal file format

DESCRIPTION

       The  Tektronix  hexadecimal  file  format  is  no longer very common.  It serves a similar purpose to the
       Motorola and Intel formats, usually used to transfer data into EPROM programmers.

   The Lines
       Most Tektronix hex files contain only Tektronix hex lines (see the next section), which always start with
       a slash (“/[rq]) character.  There are only two types of lines - data lines and a termination line.

   Data Lines
       Data  lines  have  five fields: address, length, checksum 1, data and checksum 2.  The lines always start
       with a slash (“/[rq]) character.

                                 ┌──┬─────────┬────────┬───────────┬──────┬───────────┐
                                 │/ │ Address │ Length │ Checksum1 │ Data │ Checksum2 │
                                 └──┴─────────┴────────┴───────────┴──────┴───────────┘
       Address This is a 4 character (2 byte) address that specifies where the data  in  the  record  is  to  be
               loaded into memory.

       Data Length
               The  data  length  field  is  a 2 character (1 byte) field that specifies the number of character
               pairs (bytes) in the data field.  This field never has a value of zero.

       Checksum 1
               The checksum 1 field is a 2 character (1 byte) field.  Its value is the  8‐bit  sum  of  the  six
               4‐bit values which make up the address and length fields.

       Data    The  data  field  contains  character  pairs  (bytes);  the  number of character pairs (bytes) is
               indicated by the length field.

       Checksum 2
               The checksum 2 field is a 2 character (1 byte) field.  Its value is the least significant byte of
               the sum of the all the 4‐bit values of the data field.

   Termination Line
       Termination  lines  have  three  fields: address, zero and checksum.  The lines always start with a slash
       (“/[rq]) character.

                                            ┌──┬─────────┬──────┬──────────┐
                                            │/ │ Address │ Zero │ Checksum │
                                            └──┴─────────┴──────┴──────────┘
       Address This is a 4 character (2 byte) address that specifies where to begin execution.

       Zero    The data length field is a 2 character (1 byte) field of value zero.

       Checksum
               The checksum 1 field is a 2 character (1 byte) field.  Its value is the  8‐bit  sum  of  the  six
               4‐bit values which make up the address and zero fields.

   Size Multiplier
       In  general,  binary  data  will  expand  in  sized by approximately 2.4 times when represented with this
       format.

EXAMPLE

       Here is an example Tektronix hex file.  It contains the data “Hello, World[rq] to be loaded at address 0.
              /00000D0D48656C6C6F2C20576F726C640A52
              /00000000
