Abstract

PURPOSE:To simplify the structure of a device in case when a number of input/ output signals are applied, by installing a counter for timepiece to count the clock pulses of constant period and then carrying out both the digital numerical conversion and the digital numerical time conversion for the time data. CONSTITUTION:A counter 14 carries out a count-down of the supplied clocks CL of constant period, and the command signal S4 given from a microcomputer 20 is applied to the counter 14. Then the count value is delivered from the counter 14 in the form of the signal S4. With this signal S4, the interruption signal Q4 counted down to 0 by the counter 14 is applied to the computer 20. The computer 20 compares the value equivalent to the on-duty of the output pulse P1 given from an output port 21 with the value equivalent to the on-duty of the output pulse P2. Then the value is obtained by subtracting the smaller value from the larger one, and furthermore the larger value corresponding to the period is obtained. And the input pulse P3 supplied to an input port 22 by a counter 14 is delivered in the form of output pulses P1 and P2.
