Abstract

PURPOSE:To prevent the competition of mutual transmission requests, by transmitting and receiving data through the confirmation of status by the end of transmission with an interrupting start from a transmission request and operating a transmission side with an interruption inhibiting state during that time. CONSTITUTION:When a transmission start section is called with a main program of a data transfer controller 1A, an interruption inhibiting signal (a) is immediately transmitted to a controller 2A, and a transmission interrupting signal (a) is transmitted to a processor B and the device 1A waits for a status from the B. In the B, the signal (a) from a processor A is inputted to an interruption controller 2B as a signal c detected at an interruption detector 3B. The device 2B outputs a reception start signal d. A data transfer controller 1B calls a reception start section with a signal d. When an interruption branch is made to the reception start section, the receptionable state is given to the A side via a path g with a signal f. The A judges that a status signal h from th B is possible for transmission, outputs a signal b to a data output device 4A and the data are transmitted.
