information about hex file formats.
The basic format of the hex file is:
:BBAAAATTHHHH...HHHHCC
Each data record begins with a 9-character prefix and
always ends with a 2-character checksum. All records
begin with ‘:’ regardless of the format. The individual
elements are described below.
• BB - is a two-digit hexadecimal byte count
• AAAA - is a four-digit hexadecimal address
• TT - is a two-digit record type that will be ‘00’ for
• HHHH - is a four-digit hexadecimal data word.
• CC - is a two-digit hexadecimal checksum that is

Because the Intel hex file format is byte-oriented, and
the 16-bit program counter is not, program memory
sections require special treatment. Each 24-bit
program word is extended to 32 bits by inserting a
so-called “phantom byte”. Each program memory
address is multiplied by 2 to yield a byte address.
As an example, a section that is located at 0x100 in
program memory will be represented in the hex file as
0x200.
The hex file will be produced with the following
contents:
:020000040000fa
:040200003322110096
:00000001FF
Notice that the data record (line 2) has a load address
of 0200, while the source code specified address
0x100. Note also that the data is represented in
“little-endian” format, meaning the Least Significant
Byte (LSB) appears first. The phantom byte appears
last, just before the checksum.
