* The 6-pin header (0.100" spacing) accepts 0.025" square pins.
For additional interface recommendations, refer to your
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 27-3 for more
information.
