6.0
The PIC18F1XK50/PIC18LF1XK50 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 Configuration Words. These bits
may be read out normally, even after read or code
protection. See Table 6-1 for a list of Configuration bits
and device IDs, and Table 6-3 for the Configuration bit
descriptions.
6.1
A user may store identification information (ID) in eight
ID locations, mapped in 200000h:200007h. It is
recommended 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’, q = conditional.
These bits are only implemented on specific devices. Refer to Section 3.0 “Memory Maps” to determine which bits apply based on
available memory.
DEVID registers are read-only and cannot be programmed by the user.
VREG is read-only. VREG = 1 for PIC18F1XK50 devices and VREG = 0 for PIC18LF1XK50 devices. The VREG bit value should not be
included in any Verify or Checksum operation.

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 6-2 for a complete list of
device ID values.
