To
programmer is required to read the configuration word
locations from the HEX file. If configuration word
information is not present in the HEX file, then a simple
warning 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 code memory locations
• The configuration word, appropriately masked
• ID locations
The Least Significant 16 bits of this sum are the
checksum.
Table 5-4 describes how to calculate the checksum for
each device.
Note 1: The checksum calculation differs depend-

the entire code memory can simply be
read and summed. The configuration
