NAME

       srec_fairchild - Fairchild Fairbug file format

DESCRIPTION

       The Fairchild Fairbug format has 8-byte records.  A file begins with an address record and ends with an end-of-file record.

       There are three record types in this file format.

       Address records are of the form

								       +--+------+
								       |S | nnnn |
       indicating the address for the following data records.	       +--+------+

       Data records are of the form

							       +--+------------------+---+
							       |X | ffffffffffffffff | c |
       Each  data  record  begins with an X and always contains+8-data-bytes.--The-ff+characters are hexadecimal byte values (8 bytes).  Each data
       byte is represented by 2 hexadecimal characters.  The c character is a hex digit being the the nibble-sum of the  data  bytes.	A  1-digit
       hexadecimal checksum follows the data in each data record.  The checksum represents, in hexadecimal notation, the sum of the binary equiva-
       lents of the 16 digits in the record; the half carry from the fourth bit is ignored.  The programmer  ignores  any  character  (except  for
       address	characters  and the asterisk character, which terminates the data transfer) between a checksum and the start character of the next
       data record. This space can be used for comments.

       The end-of-file record has the form

									   +--+
									   |* |
       The last record consists of an asterisk only, which indicates the end-of file.

   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 Fairchild Fairbug file.  It contains the data "Hello, World[rq] to be loaded at address 0x1000.   Notice  how  the  last
       record is padded with 0xFF bytes.
	      S1000
	      X48656C6C6F2C2057C
	      X6F726C64210AFFFF3
	      *

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 val-
	       ues 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.
