Circuit block for electronic timepiece

Abstract

Abstract PURPOSE:To achieve measurement due to a general frequency measuring instrument by selectively outputting frequency measurement signals of respective oscillation circuits in an electronic timepiece circuit block incorporating plural oscillation circuits. CONSTITUTION:The output 31 of the 1st oscillated circuit 3 and the output 41 of the 2nd oscillation circuit 4 are selected 5 through the operation of an external operation member 8 and inputted to a frequency-measurement-signal generation circuit 6. The signal 51 inputted to the generation circuit 6 is shaped and inputted as an oscillation-frequency measurement signal 61 to a frequency measuring instrument 7 connected to the outside of the circuit block to measure a frequency.
