PURPOSE:To realize the input control with its high reliability by validating the input operation of each input operation part and setting each input operation part under an input enable state as soon as a transaction is finished. CONSTITUTION:The input operation of an input operation part that is operated first is validated at every input processing part among those input operation parts kept under the input enable states. At every input processing part including an input operation part where an input operation is carried out, the input operation of the input operation part excluding the validated input operation parts is invalidated. Then the input processing part carries out the prescribed processing for the input operation part whose input operation is validated. When said processing is finished, the valid and invalid states are released for all input operation parts corresponding to the input processing parts. Thus it is possible to ensure the input control with its high reliability. |
