Filed: 2009-03-23
Abstract: <P>PROBLEM TO BE SOLVED: To easily perform version upgrading of a function of an electronic apparatus.  <P>SOLUTION: In a semiconductor chip, a signal processing circuit 23 sets both ends of an antenna 11 in a state that they are connected to earth or in a state of high impedance according to a reception signal corresponding to the radio wave received by an antenna 21. Transmission and reception of radio wave with the antenna 11 cannot be performed when both the ends of the antenna 11 are connected to earth, and therefore a radio wave communication function using a radio wave circuit 12 becomes ineffective. When both the ends of the antenna 11 are set in the state of high impedance, the reception signal corresponding to radio wave received with the antenna 11 is fed to the radio wave circuit 12 and the radio wave corresponding to signal output from the radio wave circuit 12 is emitted from the antenna 11, and therefore the radio wave communication function using the radio wave circuit 12 becomes effective. The invention is applicable to a semiconductor chip, for example.  <P>COPYRIGHT: (C)2009,JPO&INPIT
