NAME

       srec_stewie - Stewie's binary file format

DESCRIPTION

       If you have a URL for documentation of this format, please let me know.

       Any  resemblance to the Motorola S-Record is superficial, and extends only to the data records.	The header records and termination records
       are completely different.  None of the other Motorola S-Records record type are available.

   The Records
       All records start with an ASCII capital S character, value 0x53, followed by a type specifier byte.  All records consist of binary bytes.

   The Header Record
       Each file starts with a fixed four byte header record.

							       +-----+------+------+------+
							       |0x53 | 0x30 | 0x30 | 0x33 |
							       +-----+------+------+------+
   The Data Records
       Each data record consists of 5 fields. These are the type field, length field, address field, data field,  and  the  checksum.	The  lines
       always start with a capital S character.

						+-----+------+---------------+---------+------+----------+
						|0x53 | Type | Record Length | Address | Data | Checksum |
						+-----+------+---------------+---------+------+----------+
       Type    The  type  field  is  a	one byte field that specifies whether the record has a two-byte address field (0x31), a three-byte address
	       field (0x32) or a four-byte address field (0x33).  The address is big-endian.

       Record Length
	       The record length field is a one byte field that specifies the number of bytes in the record following this byte.

       Address This is a 2-, 3- or 4-byte address that specifies where the data in the record is to be loaded into memory.

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

       Checksum
	       The checksum is a one byte field that represents the least significant byte of the one's complement of the sum of the values repre-
	       sented by the bytes making up the record's length, address, and data fields.

   The Termination Record
       Each file ends with a fixed two byte termination record.

								      +-----+------+
								      |0x53 | 0x38 |
								      +-----+------+
   Size Multiplier
       In general, binary data will expand in sized by approximately 1.2 times when represented with this format.

EXAMPLE

       Here is an hex-dump example file.  It contains the data "Hello, World[rq] to be loaded at address 0.
	      0000: 53 30 30 33 53 31 10 00 00 48 65 6C 6C 6F 2C 20  S003S1...Hello,
	      0010: 57 6F 72 6C 64 0A 9D 53 38			     World..S8
