PROBLEM TO BE SOLVED: To provide a processor system, capable of informing of fault information from a slave device even when a fault occurs during the fault processing of the slave device by a master device and the fault state of the slave device is reset. SOLUTION: A general timer monitoring circuit 11 always monitors an optional timer and informs a fault reset circuit 12 of time-out in each detection of time-out. At the time of receiving the information of time-out, the circuit 12 resets a fault detection circuit 21 in an extended storage device 2 only when a fault con-trol circuit 10 does not execute fault processing at present.
