7.0
To allow portability of code, a PIC18F1XK22/LF1XK22
programmer is required to read the Configuration Word
locations from the hex file. If Configuration Word infor-
mation is not present in the hex file, then a simple warn-
ing message should be issued. Similarly, while saving
a hex file, all Configuration Word information must be
included. An option to not include the Configuration
Word information may be provided. When embedding
Configuration Word information in the hex file, it should
start at address 300000h.
Microchip Technology Inc. feels strongly that this
feature is important for the benefit of the end customer.

The checksum is calculated by summing the following:
• The contents of all program Flash locations
• The Configuration Word, appropriately masked
• ID locations (Only if any portion of program
The Least Significant 16 bits of this sum are the
checksum.
Code protection limits access to program memory by
both external programmer (code-protect) and code
execution (table read protect). The ID locations, when
included in a code protected checksum, contain the
checksum of an unprotected part. The unprotected
checksum is distributed: one nibble per ID location.
Each nibble is right justified.

Since the program Flash locations read
out differently depending on the code-
protect setting, the table describes how to
manipulate the actual program Flash
values to simulate the values that would
be read from a protected device. When
calculating a checksum by reading a
device, the entire program Flash can
simply be read and summed. The
Configuration Word and ID locations can
always be read.
