(see figure 6). dual pulse mode (mode tied to v dd ) requires two pulses with each pulse coming from the opposite comparator to occur within a timeout window of five seconds (see figure 7 ). if the adjacent pulses occur outside the timeout window then the digital processing block will restart the pulse recognition routine (figure 8). xled_en pin the xled_en pin enables the led output driver when motion has been detected. if xled_en is tied high the led pin will not toggle after motion is detected. if the xled_en is tied low the led pin will toggle when motion i s detected. during start-up the led pin will toggle irrespective of how the xled_en pin is tied.
