The Low-Voltage Programming Entry mode allows the
PIC16LF1904/6/7 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.

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
