PIC18F2XXX/4XXX FAMILY
5.0
The PIC18F2XXX/4XXX family devices have several
Configuration Words. These bits can be set or cleared to
select various device configurations. All other memory
areas should be programmed and verified prior to setting
the Configuration Words. These bits may be read out
normally, even after read or code protection. See
Table 5-1
and
5.1
A user may store identification information (ID) in eight
ID locations, mapped in 200000h:200007h. It is recom-
mended that the most significant nibble of each ID be
Fh. In doing so, if the user code inadvertently tries to
execute from the ID space, the ID data will execute as
a NOP.

The Device ID Word for the PIC18F2XXX/4XXX family
devices is located at 3FFFFEh:3FFFFFh. These bits
may be used by the programmer to identify what device
type is being programmed and read out normally, even
after code or read protection.
In some cases, devices may share the same DEVID
device revision, REV4 (DEVID1<4>), will need to be
examined to completely determine the device being
accessed.
