(1) If the device generating the interrupt has an open-drain output structure or can be 3-stated, a

pull-up resistor is required.

If the device generating the interrupt has a totem pole output structure and cannot be 3-stated, a

pull-up resistor is not required.

The interrupt inputs should not be left floating.

[1] The performance capability of a high-performance integrated circuit in conjunction with its thermal

environment can create junction temperatures which are detrimental to reliability. The maximum junction

temperature of this integrated circuit should not exceed 125 °C.
