An apparatus and method for controlling indicator lights in a device is described. In general terms, mechanisms are provided for translating network addresses of traffic going between two private domains or realms. The protection device applies to a supply node of the circuit element either the logic supply voltage under normal conditions of operation of the integrated circuit, or the high voltage under abnormal conditions of operation of the integrated circuit for breaking down the gate oxide. A system that compensates for added phase noise comprises a controller having a control algorithm and a spectrum analyzer.
