PIC18FXX2/XX8
5.0
The PIC18FXX2/XX8 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 configura-
tion 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 NOP.
5.2
The device ID word for the PIC18FXX2/XX8 is located
at 3FFFFEh:3FFFFFh. These bits may be used by the
programmer to identify what device type is being pro-
grammed 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.

2: While in Low Voltage ICSP mode, the RB5

pin can no longer be used as a general
purpose I/O. The RB5 pin should be held
low during normal operation to protect
against inadvertent ICSP mode entry.
