PROBLEM TO BE SOLVED: To provide an access interruption circuit for preventing a whole system from being hang up, a semiconductor integrated circuit, and an access interruption method.SOLUTION: An access interruption circuit 40 (41-43) arranged between a master (11-13) and a bus (3) to which at least one slave (21, 22) is connected includes: abnormal condition detection units 404, 405, 406 for detecting an abnormal condition of the master; an access interruption unit 402 which interrupts an access to a faulty master when the abnormal condition of the master is detected by the abnormal condition detection unit; and a protocol correction unit 403 which corrects a protocol of the access-interrupted master, to hold the slave in idle state.SELECTED DRAWING: Figure 9 |
