PURPOSE:To attain ease of diagnosis of an interruption function between a channel and a CPU by providing an interruption processing means to a channel connected to a dataway. CONSTITUTION:The interruption control means 11 is formed by a command processing unit 6, an interruption start register 7 and an OR gate 9. The processor 6 has a CPU number storage table 6a and when an interruption request command is transmitted from the CPU via the dataway 1, the register 7 is accessed by analyzing the command, the interruption control signal is generated and the interruption control signal in an interruption cause register 10 is read, the table 6a is referenced to specify the CPU subjected to interruption and to transmit the interruption command via the dataway 1. |
