ABSTRACT:
One aspect of the present invention is a clock switching circuit for switching between asynchronous first clock and second clock when connecting or disconnecting an interface cable having a hot-plug function. The clock switching circuit includes a first group of flip-flops for receiving an interface disconnection signal that corresponds to disconnection and connection of the interface cable in response to the first clock, and a second group of flip-flops for receiving the interface disconnection signal in response to the second clock.
