APPENDIX A:
Flash programmers process the standard HEX format
used by the Microchip development tools. The format
supported is the Intel
Please refer to Appendix A in the “MPASM™ User’s
Guide” (DS33014) for more information about hex file
formats.
The basic format of the hex file is:
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

on the line. Divide this number by two to get the
number of words per line.
representing the starting address of the data
record. Format is high byte first followed by low
byte. The address is doubled because this format
only supports 8 bits. Divide the value by two to
find the real device address.

preceding bytes in the line record.

HEX32 Format (INHX32).
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 pro-
gram 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:
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.
