<P>
<STRONG>Specification of the <NOBR>Intel-HEX</NOBR> Format</STRONG>
</P>

<P>
This object file format is supported by many cross assemblers, utilities,
and most EPROM programmers.<BR>
An <NOBR>Intel-HEX</NOBR> file is a <NOBR>7-bit</NOBR> ASCII text file,
that contains a sequence of data records and an end record. Every record
is a line of text that starts with a colon and ends with CR and LF.<BR>
Data records contain up to 16 data bytes, a <NOBR>16-bit</NOBR> load
address, a record type byte and an <NOBR>8-bit</NOBR> checksum. All
numbers are represented by upper case <NOBR>ASCII-hex</NOBR> characters.
</P>

<BLOCKQUOTE>
DATA RECORD:
</BLOCKQUOTE>
<PRE>
    Byte 1               colon (:)
         2 and 3         number of binary data bytes for this record
         4 and 5         load address for this record, high byte
         6 and 7         load address  &quot;    &quot;     &quot;     low byte
         8 and 9         record type: 00  (data record)
        10 to  x         data bytes, two characters each
       x+1 to  x+2       checksum (two characters)
       x+3 to  x+4       CR and LF
</PRE>
<BLOCKQUOTE>
A typical data record looks like
</BLOCKQUOTE>
<PRE>
                      :10E0000002E003E4F588758910F58DF58BD28E302A
</PRE>
</P>

<P>
The end record is the last line of the file.<BR>
In principle it is structured like a data record, but the number of data
bytes is 00, the record type is 01 and the load-address field is 0000.
</P>

<P>
<BLOCKQUOTE>
END RECORD:
</BLOCKQUOTE>
<PRE>
    Byte 1               colon (:)
         2 and 3         00   (number of data bytes)
         4 and 5         00   (load address, high byte)
         6 and 7         00   (load address, low byte)
         8 and 9         record type: 01  (end record)
        10 and 11        checksum (two characters)
        12 and 13        CR and LF
</PRE>
<BLOCKQUOTE>
The typical END record looks like
</BLOCKQUOTE>
<PRE>
                      :00000001FF
</PRE>
</P>

<P>
The checksum is the two's complement of the <NOBR>8-bit</NOBR> sum, without
carry, of the byte count, the two load address bytes, the record type byte
and all data bytes.
</P>
