    • 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.
    • 公开了用于激活一个或多个设备的系统和方法。 根据一个实施例,设备侦听激活码,激活码具有长度字段和掩码字段,掩码字段包括掩码值,长度字段指定掩码字段的长度到掩码的最后位 值。 在接收到激活代码时,将长度字段与存储的长度值进行比较,以确定长度字段是否满足预定义的标准。 如果长度字段满足预定义的标准,则加载激活值的地址(如果存在地址字段)并且将掩码字段的适当位(掩码值)与存储的激活值进行比较。 如果掩码值与存储的激活值匹配,则产生激活信号。 激活信号可用于激活包括整个设备的附加电路。
