Summary:PROBLEM TO BE SOLVED: To provide a microcomputer that prevents the occurrence of error in time measurement.SOLUTION: In the microcomputer, when a clock switch signal is switched, a clock selector 10 outputs a correction clock signal being the same signal as the first clock signal or the second clock signal by one pulse after the clock switch signal is switched, and then outputs a clock signal having been switched. Selectors 60-80 input a signal indicating an increment value for a first clock to an adder 90 when the first clock signal is input into the adder 90, input a signal indicating an increment value for a second clock to the adder 90 when the second clock signal is input into the adder 90, and input a signal indicating an increment value corresponding to a correction period to the adder 90 when the correction clock signal is input into the adder 90.
