An apparatus and method for exchanging data between cellular modem software and application engine software of a communications device is disclosed that involves providing a communications module that facilitates communications between the cellular modem software and the application engine software. The circuit has at least one circuit path, which is determined by the data state of the input data signal, to couple the radio frequency carrier signal to the antenna feedpoint to adjust the phase. The system can revise the memory compiler without requiring a user to make a decision as to the necessity of the revision of the memory compiler. The spacer feet support the corresponding spacer wall on the faceplate structure.
