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 (pages 32 through 37) describes how to
calculate the checksum for each device.

ing on the code protect setting. Since the
code memory locations read out differ-

ues to simulate the values that would be
read from a protected device. When cal-
culating a checksum by reading a device,
the entire code memory can simply be
read and summed. The configuration
word and ID locations can always be
read.
