METHOD OF CONTROLLING DATA PROCESSING SYSTEM AND DATA PROCESSING SYSTEM

A method of controlling a data processing system including a master, a slave, and a bus provided on a path connecting the master and the slave. The method of controlling the data processing system includes: performing normal processing and performing anomaly avoidance processing to avoid an anomalous state when the slave is anomalous. The performing of the anomaly avoidance processing includes: resetting the slave; and performing a first pseudo response which includes disconnecting communication between the bus and the slave, generating first pseudo response signals corresponding one to one to the plurality of command signals in place of the slave, and transmitting the first pseudo response signals to the master via the bus.
