27.2
The Low-Voltage Programming Entry mode allows the
PIC16F193X/LF193X 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.
27.3
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.
