The LVP bit in configuration register, CONFIG4L,
enables Low-Voltage Programming (LVP). When LVP
is enabled, the microcontroller can be programmed
without requiring high voltage being applied to the
MCLR/V
dedicated to controlling Program mode entry and is not
available as a general purpose I/O pin.
LVP is enabled in erased devices.
