PURPOSE:To correctly enable an interruption request from an interruptor to be accepted by a request opponent, by discriminating an identification code delivered from an interrupt handler by the interruptor, and sending a status signal corresponding to a discriminated result to the interrupt handler. CONSTITUTION:The interrupt handler 3 sends the identification code to distinguish the handler from another interrupt handler 4 to the interruptor 5 corresponding to the interruption request from the interruptor 5. The interruptor 5 discriminates the identification code, and sends the status signal corresponding to the discriminated result to the interrupt handler 3. In other words, the interruptor 5 discriminates the interrupt handler from the identification code delivered from the interrupt handler 3, and the interrupt handler 3 discriminates the interruptor by the status signal sent from the interruptor 5. In such a way, the interruption request from the interruptor can be accepted by the processor of the request opponent correctly. |
