Clock synchronization circuit and semiconductor device provided therewith |
摘要 |
An object is to provide a clock synchronization circuit capable of stable communication even in the case where different clock signals are used in a plurality of circuits, and a semiconductor device provided therewith. Circuit for detecting a change point of received data, and outputting a reset signal; reference clock generating means for generating a clock signal; and circuit for counting the clock signals outputted from the reference clock generation means, and resetting a counter value obtained by counting the clock signals in the case where the reset signal is inputted are provided.
