PROBLEM TO BE SOLVED: To provide a highly reliable electronic apparatus which does not generate a malfunction even when data prestored in a nonvolatile memory changes to a fixed value due to reduction of a power supply voltage.SOLUTION: A clock is configured so as to stop operation of pointers when output data from both bit 1 and bit 0 of a nonvolatile memory 5 are fixed values. A pulse stop determination circuit 12 determines that the output data has changed to fixed values due to reduction of a power supply voltage, and operation of the pointers is controlled to stop. In addition to stop of operation, the electronic circuit is also applicable to control of voltage alarm operation or a function such as a chronograph function depending on settings. |
