PIC18FXX2/XX8
Users may store identification information (ID) in eight
ID registers. These ID registers are mapped in
addresses 200000h through 200007h. The ID locations
read out normally, even after code protection is applied.
Locations 300001h through 30000Dh are reserved for
the configuration bits. These bits may be set to select
various device options, and are described in
Section 5.0. These configuration bits read out normally
even after code protected.
Locations 3FFFFEh and 3FFFFFh are reserved for the
device ID bits. These bits may be used by the program-
mer to identify what device type is being programmed,
and are described in Section 5.0. These configuration
bits read out normally even after code protection.

CONFIGURATION AND ID LOCATIONS FOR PIC18FXX2/XX8 DEVICES
2.3.1
Memory in the address space 000000h to 3FFFFFh is
addressed via the Table Pointer, which is comprised of
three pointer registers:
• TBLPTRU, at address 0FF8h
• TBLPTRH, at address 0FF7h
• TBLPTRL, at address 0FF6h
The 4-bit command, ‘0000’ (Core Instruction), is used
to load the Table Pointer prior to using many Read or
Write operations.
