PROBLEM TO BE SOLVED: To minimize the wrong recognition due to the noises by correcting the input signal by a selected correction method and outputting a corrected signal as a result of correction. SOLUTION: This microcomputer is provided with an input terminal IN, an input buffer 11, a correction function part 20 and a noise elimination circuit 10. In such a constitution, the function part 20 eliminates the noise of an input signal and corrects this signal. The signal inputted to the terminal IN is turned into a signal 21 via the buffer 11 and then inputted to the part 20. A selector 26 of the part 20 selects a correction method against the input signal based on the output signals of a two-input AND circuit 23 and two-input NOR circuits 24 and 25. Thus, a signal 27 that is corrected at the part 20 is processed by the circuit 10 and an internal signal is generated. |
