WI pin connection in L26-DR GNSS

Hi, the datasheet says this is an interrupt to detect a big inclination of the vehicle but is it really necessary for the dead reckoning or another function?, what if I leave that pin unconnected?


1.L26-DR module cannot determine what causes the vehicle to have an inclination angle. It wakes up the MCU to judge whether the vehicle is towed by a trailer or is running normally on an uphill road.
2.The pin functions are as described above.If not used, leave it open.
