Abstract: PURPOSE: To provide a circuit capable of generating control pulse trains in various operating conditions by using one specified bit counter for both of a normally operating condition and a one-operation time reset condition. CONSTITUTION: An input part receives three types of signals, a signal CLOCK, a signal RESET and a signal PULSE. The signal CLOCK is input to a frequency: division 4 to generate two frequency signals. A counter: 50M2 is provided with a counter 2A to generate a signal SX with the second frequency, which is a quick clock time reset pulse basic signal SX with high and low logic conditions. A multiplexer MUX 3 selectively sends both of a quick time reset signal SX and a slow time reset signal SN as the functions of a signal SECS to an output part S1 or S2 in a circuit. A counter: 11 bit 1 receives the signal PULSE, the signal RESET, the signal QSX and the first frequency signal to selectively control the reversion of a current in a clock motor.

Abstract: An electronic circuit for controlling a quartz clock with hands, particularly for installation on board motor vehicles, is simpler and cheaper than circuits according to the prior art since it comprises a single 11-bit counter (CNT-11Bit). This circuit allows "fast" or "slow" resetting of the time by a single push button.
