<p>A system comprises an issuing end device for issuing at least one of read access and write access and a receiving end device for receiving the access issued by the issuing end device. The issuing end device issues access including the target address which is subject to the access to the receiving end device and, if having not received an address response indicating the presence of the storage area corresponding to the target address of the access from the receiving end device within a predetermined address response time-out period, detects the time-out. If the address response time-out has been detected or depending on the reception of the access reply indicating that the receiving end device is ready for receiving the next access therefrom, the issuing end device issues the next access to the receiving end device. The receiving end device, if having the storage area corresponding to the target address of the received access, provides a tester for transmitting the address response to the issuing end device.</p> |
