Abstract
A transmission LSI calculates a buffer usage rate in accordance with data stored in a buffer in a transmission data processing unit and determines, in accordance with the calculated buffer usage rate, the number of signal lines that perform a phase readjustment and the timing thereof. Then, the transmission LSI and a receiving LSI perform a phase adjustment using some of the signal lines and continues a data transfer using the rest of the signal lines. Accordingly, it is possible to maintain the optimum phase of a clock without delaying the data transfer.
