NAME

       srec_tektronix_extended - Tektronix Extended hexadecimal file format

DESCRIPTION

       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
       Lines  always  start with a percent (%) character.  Each line consists of 5 fields.  These are the length
       field, the type field, the checksum, the address field (including address length), and the data field.

   The Fields
                                  ┌───┬────────┬──────┬──────────┬─────────┬──────┐
                                  │ % │ Length │ Type │ Checksum │ Address │ Data │
                                  └───┴────────┴──────┴──────────┴─────────┴──────┘

       Record Length
               The record length field is a 2 character (1 byte) field that specifies the number  of  characters
               (not bytes) in the record, excluding the percent.

       Type    The  type  field  is  a  1  character  field  that  specifies  whether  the record is data (6) or
               termination (8).

       Checksum
               The checksum is an 2 character (1 byte) field that represents the sum of all the nibbles  on  the
               line, excluding the checksum.

       Address This  is  a  9  character  field.   The first character is the address size; it is always 8.  The
               remaining 8 chgaracters are the 4‐byte address that specifies where the data is to be loaded into
               memory.

       Data    The data field contains the executable code, memory‐loadable data or descriptive  information  to
               be transferred.

   Record Types
       6       A record containing data.  The data is placed at the address specified.

       8       A termination record.  The address field may optionally contain the address of the instruction to
               which control is passed.  There is no data field.

   Size Multiplier
       In  general,  binary  data  will  expand  in  sized by approximately 2.5 times when represented with this
       format.

EXAMPLE

       Here is an example Tektronix extended file.  It contains the data “Hello, World” to be loaded at  address
       0x006B.
