ABSTRACT:
If a block read cannot be used to read out from a configuration ROM information, the number of times of issue of a quadlet read request increases. This degrades the processing efficiently of a device that issues the request. In addition, the bus occupation ratio of a 1394 serial bus by the request becomes high, and the speed of processing through the 1394 serial bus decreases. To solve these problems, information stored in the configuration ROM area of a device is read out, and it is determined on the basis of the readout information that configuration information identical to the configuration ROM information is stored in an address area (block readable area) different from the configuration ROM area, the offset is changed, and the configuration information is read out from the address area different from the configuration ROM area.
