PURPOSE:To easily adjust a pace, and also to elevate the reliability, by shifting the timing of an operation time of a temperature detecting circuit part, so that it does not coincidence with an operation time of a circuit which consumes a large current instantaneously, such as a driving circuit of a motor, a lamp lighting circuit, etc. CONSTITUTION:A block diagram of an IC built-in temperature detecting circuit part which is provided on an electronic timepiece is shown in one point chain line 2000, and a block diagram showing one example of the constitution part required for the electronic timepiece, except a temperature detecting circuit part is shown in one point chain line 2100. A frequency divider 219 generates a reference clock signal for deciding a repeated period of a logical brake operation. A logical brake timing controlling circuit 216 receives a signal of a frequency divider 219 for generating a logical brake reference clock, sends an operation start signal to the temperature detecting circuit part, and also receives an end signal of a temperature detecting operation. Furthermore, the controlling circuit 216 sends a signal which is operated for alternatively selecting a logical brake data C of temperature compensation or a logical brake data D of an oscillator, to a latch circuit or a switching circuit 215. |
