A method of transferring data in one access cycle between two devices over a communications bus. Data is read from a predetermined location in the first deyice. The data is also latched into a temporary register. Data is simultaneously written into a predetermined location of a second device. The read operation of the first device is terminated and the data from the temporary register is applied to the second device simultaneously with the termination step so that data is available to the second device notwithstanding the fact that the first device has ceased transmission.
