The Low-Voltage Programming Entry mode allows the
PIC16F/LF1946/47 devices to be programmed using
V
Configuration Word 2 is set to ‘1’, the low-voltage ICSP
programming entry is enabled. To disable the
Low-Voltage ICSP mode, the LVP bit must be
programmed to ‘0’.
Entry into the Low-Voltage Programming Entry mode
requires the following steps:
1.
2.
Once the key sequence is complete, MCLR must be
held at V
maintained.
If low-voltage programming is enabled (LVP = 1), the
MCLR Reset function is automatically enabled and
cannot be disabled. See
information.
The LVP bit can only be reprogrammed to ‘0’ by using
the High-Voltage Programming mode.

Connection to a target device is typically done
through an ICSP™ header. A commonly found
connector on development tools is the RJ-11 in the
6P6C (6 pin, 6 connector) configuration. See
