5.1
The Device ID Word for the PIC18F2XJXX/4XJXX
family devices is located at 3FFFFEh:3FFFFFh. These
read-only bits may be used by the programmer to
identify what device type is being programmed and
read out normally, even after code protection has been
enabled. The process for reading the device IDs is
shown in Figure 5-1. A complete list of device ID values
for the PIC18F2XJXX/4XJXX family is presented in
Table 5-8.

TABLE 5-8: DEVICE ID VALUE (CONTINUED)
5.2
The checksum is calculated by summing the contents of
all code memory locations and the device Configuration
Words, appropriately masked. The Least Significant
16 bits of this sum are the checksum.
The checksum calculation differs depending on
whether or not code protection is enabled. 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 Configuration Words can always be read.
