Abstract
A slave interface is equipped with a register that stores a retry set value SRI that is unique for a slave device and a pseudo random number generator that generates a random number value RN, and when a non-acknowledgement response is sent corresponding to a transmission request REQb from a master device, the slave interface transmits non-acknowledgement response incidental information NAINFb that includes the retry set value SRI and the random number value RN to the master interface. The master interfaceextracts the retry set value SRI and the random number value RN from the non-acknowledgement response incidental information NAINFb, calculates a retry interval value by adding these, and when the interval time according to the retry interval value has passes, resends the transmission request REQb to the slave device. Since the retry interval time is independently set every time, live-lock may be prevented.
