srec_fairchild(5)	      File Formats Manual	     srec_fairchild(5)

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 hexa-
       decimal checksum	follows	the data in each data  record.	 The  checksum
       represents,  in hexadecimal notation, the sum of	the binary equivalents
       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	trans-
       fer)  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
	      *
