If the device generating the Interrupt has an open-drain output structure or

can be tri-stated, a pull-up resistor is required.

If the device generating the Interrupt has a totem-pole output structure and

cannot be tri-stated, a pull-up resistor is not required.

The Interrupt inputs should not be left floating.
