PIC18FXX2/XX8
TABLE 5-3:
5.4
To allow portability of code, a PIC18FXX2/XX8 pro-
grammer 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
warning message should be issued. Similarly, while
saving a HEX file, all configuration word information
must be included. An option to not include the configu-
ration 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.

Device ID bits
These bits are used with the DEV2:DEV0 bits in the DEVID1 register to
identify part number.
Device ID bits
These bits are used with the DEV10:DEV3 bits in the DEVID2 register to

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-

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