PURPOSE:To facilitate the production of an interruption processing program and to realize the separate execution of operations, by securing such a mechanism where a register accepting means accepts an asynchronous processing program every time an interruption accepting means accepts an interruption. CONSTITUTION:When a timer interruption is applied to a CPU 2 while a main processing part 102 is executing a program, the CPU 2 shifts the control to a timer interruption processing part 103. Then the registration is carried out via an asynchronous processing part 104 based on an interruption processing program of the part 103 and the control is shifted to an asynchronous processing program. If the release of processing program is both parts 102 and 104 produces the conflict, the control is returned to the part 103 and the operation is kept waiting until the start of the release of the program of the part 102. Thus it is not required to produce the program stored in a data receiving part 104a as an interruption process. In such a way, the interruption processing program is easily produced and at the same time another operation can be carried out while having communication with outside. |
