GND

Ground

1. A 100 Ohms resistor should be placed between this pad and the other polarity pad.

2. In normal mode should be pulled to ground.

3. Application requires pull-down 10 +/-1% KOhm resistor.

4. This pin can be left unconnected since they are configured as inputs with internal pull-down at reset.

5. The 65th pin serves as a ground and thermal pad.
