Using Sample Rate at MMA8491Q

I want to wake my microcontroller up using the accelerometer. Do i need a host microcontroller to use the sample rate settings at mma8491? Because it is getting meanless for me. I want my microcontroller to sleep all the time. My accelerometer needs to measure wheter there is a movement or not; then if there is a movement, it must awaken my microcontroller.
