<P>PROBLEM TO BE SOLVED: To restrain the number of gates from increasing, and to reduce a cost. <P>SOLUTION: This noise eliminator is provided with resistors (211, 212) for assigning an input and output buffer of a selection object out of the plurality of input and output buffers connected to a general purpose input and output interface, at least one selector (201, 202) for selecting the input and output buffer of the selection object according to values of the resistors and having the number more reduced than the number of the plurality of input and output buffers, and noise removal circuits (221, 222) connected respectively to the selectors. <P>COPYRIGHT: (C)2004,JPO |
