Electronic circuit and electronic timepiece

An electronic circuit comprising:

• an oscillator circuit configured to output a clock signal;
• a function control circuit configured to output a function control signal that sets a function mode and a non-function mode;
• an internal circuit;
• an initialization circuit configured to output an initialization control signal that changes between a first level executing an internal circuit initialization process, and a second level cancelling the initialization process;
• an initialization control circuit configured to control the initialization circuit;
• an input control circuit configured to change input and non-input of the function control signal to the initialization control circuit;
• and
• an initialization state holding circuit;
• the initialization circuit outputting the initialization control signal at the first level when a battery is installed;
• the input control circuit not inputting the function control signal to the initialization control circuit when the initialization control signal is output at the first level, and inputting the function control signal to the initialization control circuit when the initialization control signal is output at the second level;
• the initialization state holding circuit outputting an initialization state hold signal to the initialization control circuit when the function control signal is not input to the initialization control circuit;
• and
• the initialization control circuit, when the initialization state hold signal is input, continuing to output the initialization control signal at the first level to the initialization circuit until the clock signal is output, and
• when the initialization state hold signal was input and the clock signal then output, outputting the initialization control signal at the second level to the initialization circuit.
