PURPOSE:To obtain an electronic time piece circuit with a simplified circuitry by having a day counting circuit serving as a second counting circuit for the stop watch function. CONSTITUTION:A counting circuit 24 has the first function of counting signals to be inputted into an input terminal I, the second function of resetting counts with a reset signal 650, and the third function of receiving and presetting an input of a data signal 024 by a stop watch signal 160 to an instruction input terminal L. Another memory circuit 37 memorizes an output signal 240 from a counting output terminal Q of the counting circuit 24 based on the stop watch signal 160. A switch circuit 55 outputs a data input signal 024 to the counting circuit 24 by the stop watch signal 160 likewise. A decision circuit 65 judges the output 240 of the counting circuit 24 and generates a reset signal 650 to a reset terminal R1 receiving the signal 160. This has the function of judging 60sec and the function of judging 32 days. |
