<P>PROBLEM TO BE SOLVED: To provide a data transfer system, data transfer device, and data transfer method capable of improving a degree of freedom in design. <P>SOLUTION: Both of a logical circuit 15 of a first transfer device 10 and a logical circuit 24 of a second transfer device 20 compare coincidence/non-coincidence between a transmission state signal Ts, where a signal level is changed over when transfer data TD is transmitted from the first transfer device 10 to the second transfer device 20, and a reception state signal Rs, where a signal level is changed over when the transfer data TD is received by the second transfer device 20. The fetching of a new data signal D1 in the first transfer device 10 and the reception of the transfer data TD in the second transfer device 20 are alternately permitted in accordance with comparison results in the logical circuits 15, 24. <P>COPYRIGHT: (C)2013,JPO&INPIT |
