PROBLEM TO BE SOLVED: To output a clock selection signal which satisfies a switching specification determined between a clock generating device and slave devices even when the number of slave devices to be connected to the clock generating device changes and load capacity of a connection destination changes.SOLUTION: The clock generating device detects the number of slave devices connected in a slave device mounting detection part, and notifies a buffer type selection part of the detected number. In the buffer type selection part, a buffer type when the clock selection signal is output is selected based on this notification. |
