Date Oct. 22, 1987.A method and apparatus for transferring data words from a transmitter register to a receiver register between transmitting and receiving equipment which are respectively driven by a first and a second clock. A state signal which can assume two alternative definite values is applied from the transmitter side to the receiver side, whereafter the state of the signal is changed from the transmitter side. The state signal is processed logically to obtain the start of a write signal which achieves writing into the receiver register and the write signal is interrupted with the aid of the receiver side clock signal.
