PURPOSE:To obtain an integrated circuit suitable for a timepiece which has plural functions in combination, by deciding functions of plural common use counters for realizing plural functions according to a terminal input code. CONSTITUTION:A pulse signal of specific frequency from an oscillating circuit 1 is frequency-divided by a frequency dividing circuit 2. A signal to be selected among various functions is encoded and inputted to a terminal 3, and a signal converting circuit 4 generates a function selection signal. Then, a reference timepiece circuit 5 generates a reference timepiece signal by the output of the frequency dividing circuit 2 to switch an alarm and different-timepiece counter 6 and a chronograph and timer counter 7 by the signal from the circuit 4. Contents of the counters are displayed through a display circuit 9 by putting a display selecting circuit 8 in operation by a signal from a display selection input terminal 10. |
