The PIC18FXX39 has several configuration words.
These bits can be set or cleared to select various
device configurations. All other memory areas should
be
configuration words. These bits may be read out
normally, even after read or code protected.
5.1
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 0Fh. In doing so, if the user code inadvertently
tries to execute from the ID space, the ID data will
execute as a NOP.
5.2
The device ID word for the PIC18FXX39 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 protected.

The LVP bit in configuration register, CONFIG4L,
enables low voltage ICSP programming. The LVP bit
defaults to a ‘1’ from the factory.
If Low Voltage Programming mode is not used, the LVP
bit can be programmed to a ‘0’ and RB5/PGM becomes
a digital I/O pin. However, the LVP bit may only be
programmed by entering the High Voltage ICSP mode,
where MCLR/V
programmed to a ‘0’, only the High Voltage ICSP mode
is available and only the High Voltage ICSP mode can
be used to program the device.
