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 38-1 .

Pin Description*
1 = VPP /MCLR
2 = VDD Target
3 = VSS (ground)
4 = ICSPDAT
5 = ICSPCLK
6 = No Connect
Another connector often found in use with the PICkit™ programmers
is a standard 6-pin header with 0.1 inch spacing. Refer to Figure 38-2 .
For additional interface recommendations, refer to the specific
device programmer manual prior to PCB design.
It is recommended that isolation devices be used to separate the
programming pins from other circuitry. The type of isolation is highly dependent on the
specific application and may include devices such as resistors, diodes, or even jumpers.
See Figure 38-3 for more information.

Note:
Note: The 6-pin header (0.100"
spacing) accepts 0.025" square pins.
