22 /* This is what Intel Hex files look like:
24 1. INTEL FORMATS
26 A. Intel 1
28 16-bit address-field format, for files 64k bytes in length or less.
30 DATA RECORD
31 Byte 1 Header = colon(:)
32 2..3 The number of data bytes in hex notation
33 4..5 High byte of the record load address
34 6..7 Low byte of the record load address
35 8..9 Record type, must be "00"
36 10..x Data bytes in hex notation:
37 x = (number of bytes - 1) * 2 + 11
38 x+1..x+2 Checksum in hex notation
39 x+3..x+4 Carriage return, line feed
41 END RECORD
42 Byte 1 Header = colon (:)
43 2..3 The byte count, must be "00"
44 4..7 Transfer-address (usually "0000")
45 the jump-to address, execution start address
46 8..9 Record type, must be "01"
47 10..11 Checksum, in hex notation
48 12..13 Carriage return, line feed
50 B. INTEL 2
52 MCS-86 format, using a 20-bit address for files larger than 64K bytes.
54 DATA RECORD
55 Byte 1 Header = colon (:)
56 2..3 The byte count of this record, hex notation
57 4..5 High byte of the record load address
58 6..7 Low byte of the record load address
59 8..9 Record type, must be "00"
60 10..x The data bytes in hex notation:
61 x = (number of data bytes - 1) * 2 + 11
62 x+1..x+2 Checksum in hex notation
63 x+3..x+4 Carriage return, line feed
65 EXTENDED ADDRESS RECORD
66 Byte 1 Header = colon(:)
67 2..3 The byte count, must be "02"
68 4..7 Load address, must be "0000"
69 8..9 Record type, must be "02"
70 10..11 High byte of the offset address
71 12..13 Low byte of the offset address
72 14..15 Checksum in hex notation
73 16..17 Carriage return, line feed
75 The checksums are the two's complement of the 8-bit sum
76 without carry of the byte count, offset address, and the
77 record type.
79 START ADDRESS RECORD
80 Byte 1 Header = colon (:)
81 2..3 The byte count, must be "04"
82 4..7 Load address, must be "0000"
83 8..9 Record type, must be "03"
84 10..13 8086 CS value
85 14..17 8086 IP value
86 18..19 Checksum in hex notation
87 20..21 Carriage return, line feed
89 Another document reports these additional types:
91 EXTENDED LINEAR ADDRESS RECORD
92 Byte 1 Header = colon (:)
93 2..3 The byte count, must be "02"
94 4..7 Load address, must be "0000"
95 8..9 Record type, must be "04"
96 10..13 Upper 16 bits of address of subsequent records
97 14..15 Checksum in hex notation
98 16..17 Carriage return, line feed
100 START LINEAR ADDRESS RECORD
101 Byte 1 Header = colon (:)
102 2..3 The byte count, must be "02"
103 4..7 Load address, must be "0000"
104 8..9 Record type, must be "05"
105 10..13 Upper 16 bits of start address
106 14..15 Checksum in hex notation
107 16..17 Carriage return, line feed
109 The MRI compiler uses this, which is a repeat of type 5:
111 EXTENDED START RECORD
112 Byte 1 Header = colon (:)
113 2..3 The byte count, must be "04"
114 4..7 Load address, must be "0000"
115 8..9 Record type, must be "05"
116 10..13 Upper 16 bits of start address
117 14..17 Lower 16 bits of start address
118 18..19 Checksum in hex notation
119 20..21 Carriage return, line feed. */
