PIC18F2423/2523/4423/4523
5.0
The
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 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, - = unimplemented. Shaded cells are unimplemented, read as ‘0’.
Unimplemented in PIC18F2423/4423 devices; maintain this bit set.
DEVID registers are read-only and cannot be programmed by the user.
The ‘x’s in DEVID1 contain the device revision code.

The device ID word for the PIC18F2423/2523/4423/
4523 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.
