PIC18F2XK20/4XK20
5.0
The PIC18F2XK20/4XK20 devices have several
Configuration Words. These bits can be set or cleared
to select various device configurations. All other mem-
ory areas should be programmed and verified prior to
setting Configuration Words. These bits may be read
out normally, even after read or code protection. See
Table 5-1 for a list of Configuration bits and device IDs
and Table 5-3 for the Configuration bit descriptions.
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.

x = unknown, u = unchanged, – = unimplemented. Shaded cells are unimplemented, read as ‘0’.
These bits are only implemented on specific devices. Refer to Section 2.3 “Memory Maps” to determine which bits
apply based on available memory.
DEVID registers are read-only and cannot be programmed by the user.

The device ID word for the PIC18F2XK20/4XK20
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. See Table 5-2 for a
complete list of device ID values.
