摘要： Systems and methods for activating one or more devices are disclosed. According to one embodiment, the device listens for an activate code, the activate code having a length field and a mask field, the mask field including a mask value, the length field specifying a length of the mask field to a final bit of the mask value. Upon receiving the activate code, the length field is compared to a stored length value for determining whether the length field meets a predefined criterion. If the length field meets the predefined criterion, an address of the activate value is loaded (if an address field is present) and the appropriate bits (mask value) of the mask field are compared to a stored activate value. An activate signal is generated if the mask value matches the stored activate value. The activate signal can be used to activate additional circuitry including the entire device.
