ABSTRACT:
A transmission cancellation section is provided on a bus connecting a master and a slave. During a reset of the master, the transmission cancellation section blocks the bus so that an invalid command flowing on the bus does not reach the slave and executes, instead of the master stopped by the reset operation, generation of data which corresponds to an access request command already output to the slave and is to be sent to the slave and receiving of data from the slave.
