| Zusammenfassung: | PURPOSE: An electric circuit is provided to test surely a circuit component to be tested at minimum cost. CONSTITUTION: The electric circuit includes a plurality of circuit components and at least one circuit component can be tested independently of other circuit components. And, data are not outputted into a bus during a test and other data are outputted into the bus instead of data outputted into the bus in usual operation. An output driver consumes a little energy when the output data are not converted or just changed little. |
