MMA8451 interrupt pin default state

Hi, I'm using an MMA8451 accelerometer to wake an MCU from deep sleep by pulling the reset line low momentarily when the device detects movement.

 

I understand the MMA8451 interrupt outputs can be configured to open drain, but that they are push-pull by default, which may interfere with the startup and operation of the MCU before I can configure them as open drain.

 

Can you please confirm what state the interrupt pins will be in (e.g. high, low, floating) when power is first applied?

 

Thanks,

Michael.
