BQ30z554-R1 unused GPIO and GPOD pins

How should the GPIO and GPOD pins be terminated on the BQ30z554-R1 if they will not be used? Can I just use a capacitor to ground?

You can leave both of these pins open, if unused.

Could RF noise cause an issue on these pins if they are left open? If the precharge settings are either internal precharge or no precharge, will this pin ever be energized? Can I connect it with a resistor to ground?

I would place a cap on the pins, if RF is a concern. The pins have internal pull-up resistors.

Exactly what I needed to know. Thank you!
