Hello, I'm using accelerometer MMA8451QT only for motion detection via interupt. Device working fine with one exception, when I put device on edge (chip on edge, edge with dot on table, dot on right side) then i receive contionous interupts for movement.

By trial error i found that issue is in Y axis, when I disable motion sensing on Y everything works fine and I cannot find any other position with this behavior.

Code is based on example from AN4070.
