Abstract:
1. A data transfer apparatus comprising: a clock transmitting unit configured to transmit a first clock to a target for data transfer that is situated at a distance from the data transfer apparatus; a data transmitting unit configured to transmit in synchronization with the first clock data including a start signal to the target; a response receiving unit configured to receive from the target a response having therein the start signal and output a first response based on the response received; a clock generating unit configured to receive the first clock and generate a second clock based on the first clock, wherein the second clock is delayed less than one clock cycle from the first clock; a response generating unit configured to generate in synchronization with the second clock a second response based on the first response; and a selector configured to select any one of the first response and the second response depending on the distance.
