<P>PROBLEM TO BE SOLVED: To prevent output of erroneous data, even if storage data to be outputted from a data storage circuit are different from present input data. <P>SOLUTION: A synchronization circuit 1 is provided with a data storage circuit 5 for storing input data D1 for each predetermined cycle; and an error data output preventing circuit 2 for outputting finalized data if the input data D1 stored in the data storage circuit 5 has been finalized, and outputting the data finalized immediately before if the stored input data D1 has not been finalized. <P>COPYRIGHT: (C)2008,JPO&INPIT |
