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 Section 6.3 “MCLR” for more
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
Figure 27-2.
