In this mode, the RB5/KBI1/PGM pin is dedicated to the
programming function and ceases to be a general pur-

must be applied to the RB5/KBI1/PGM pin, provided the
LVP bit is set. 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/KBI1/PGM
becomes a digital I/O pin. However, the LVP bit may
only be programmed when programming is entered
with V
It should be noted that once the LVP bit is programmed
to ‘0’, only the High-Voltage Programming mode is
available and only High-Voltage Programming mode
can be used to program the device.
When using low-voltage ICSP, the part must be sup-
plied 4.5V to 5.5V if a bulk erase will be executed. This
includes reprogramming of the code-protect bits from
an on-state to an off-state. For all other cases of low-
voltage ICSP, the part may be programmed at the
normal operating voltage. This means unique user IDs
or user code can be reprogrammed or added.
