PIC18F6X2X/8X2X
5.0
The PIC18F6X2X/8X2X devices have several configu-
ration 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 con-
figuration 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 recom-
mended 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 PIC18F6X2X/8X2X 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 pro-
grammed 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.
