PIC12F/LF1822/PIC16F/LF1823
28.2
The Low-Voltage Programming Entry mode allows the
PIC12F/LF1822/16F/LF1823
programmed using V
When the LVP bit of 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
