TCA9535: TCA9535 UNUSED INTERRUPT PIN

Part Number: TCA9535


Hi Team,

As per datasheet, 'a pin configured as an output cannot cause an interrupt'.

If I am using a IO expander with all the IO ports as outputs, I need not connect Interrupt INTP pin.

Can I leave that pin open as NC (not connected), as it is a open drain pin. Please confirm on default hardware configuration for interrupt pin, if unused 

Awaiting response
