Abstract
PURPOSE:To decrease the area of an IC chip by using both temperature compensation and initial frequency adjustment of a crystal oscillator based on logic regulation, ?and sharing a pad in common for adjusting a temperature sensor register and initial adjusting the frequency. CONSTITUTION:When writing is performed to a temperature sensor PROM68 based on the data in an external counter, a high signal is given to a pad 78. Then, a voltage of a -30V or less is applied to the positive side of the pad corrsponding to the data in the external counter of a pad 80, and writing is performed. When the compensating data corresponding to the frequency error of the crystal oscillator are given to the pad 80 under the state signals are not inputted to the pad 78 from the outside, the writing is performed to a PROM group 69 for logic regulation.
