Abstract
A device is operated in a low power mode of operation. The device receives a differential signal that includes a first polarity signal and a second polarity signal. A slope of a first direction is detected in the differential signal and a slope of a second direction is detected in the differential signal. A wakeup of the device is caused in response to the detection of the first slope of the differential signal and the second slope of the differential signal.
