       srec_tektronix_extended - Tektronix Extended hexadecimal file 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
       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, the length field, the type field and the

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

               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

       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.


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