Abstract
A data transfer system which can surely transfer data between two function circuits which operate synchronously with different clock frequencies. A data loading signal is generated just before timing when edges of two clocks of different frequencies coincide. Only information data received by the function circuit on a transfer data reception side within an existence period of the data loading signal is determined to be valid.
