PIC18FXXK80 FAMILY
5.0 CONFIGURATION WORD
The PIC18FXXK80 family of devices has 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 for a list of Configuration bits
and Device IDs, and Table 5-3 for the Configuration bit
descriptions.
5.1 ID Locations
A user may store Identification (ID) information 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.

Note 1:

x = unknown, u = unchanged, — = unimplemented, q = value depends on condition. Shaded cells are unimplemented, read as ‘0’.
Only implemented in 64-pin devices.
See Register 28-13 in the “PIC18F66K80 Family Data Sheet” for DEVID1 values. DEVID registers are read-only and cannot be
programmed by the user.
This bit must be maintained as ‘0’ on 28-pin PIC18F2XK80 and 40/44-pin PIC18F4XK80 devices.
