摘要：PROBLEM TO BE SOLVED: To provide a data transfer circuit for controlling priority to each blade. SOLUTION: The data transfer circuit 10 of a shelf manager 1A is provided with a bus right instruction part 16 for generating a command CMD for instructing whether to inhibit transmission of data DATA using bus wiring 4 for management to each blade 2Aa to 2An, and the command CMD is output from a control part 12 via an output part 13 and an output driver 14d to the bus wiring 4 for management. Meanwhile, the data transfer circuit 20 of each blade 2Aa to 2An is provided with a bus right register 26 for storing a command CMD transmitted via the bus wiring 4 for management, and when the transmission of data using the bus wiring 4 for management is not inhibited by the command CMD, data to be transmitted from a control part 22 are given to an output part 23. Thus, it is possible to control priority to each of blades 2Aa to 2An. COPYRIGHT: (C)2008,JPO&INPIT
