PURPOSE:To enable a pseudo operation for the end interruption of asynchronism due to the movable part of a real device by asynchronously generating the data transfer end interruption of a pseudo input/output device. CONSTITUTION:This device is equipped with an adjusting time width storing means 446a to set and store a data transfer processing and the upper and lower limits of the processing adjusting time in advance, adjusting time generating means 445c, adjusting time storing means 446b to store the generated adjusting time, and adjusting time setting means 445d to set the adjusting time to this means 446b. Further, an end report transfer means 448 is provided to report the end of data transfer to a CPU by an interruption processing after the lapse of the adjusting time, and an adjusting time measuring means 442 is provided to report the passage of the adjusting time to the end report transfer means 448 while monitoring the passage of the adjusting time. Then, the asynchronous end interruption can be generated by changing the setting of the adjusting time. Thus, the pseudo operation is enabled for the asynchronous end report as in the real device. |
