Abstract
A clock adjustment circuit delays a phase of a clock signal on the basis of a TAP value so as to output an adjusted clock signal. By synchronizing transmission data with the adjusted clock signal, reception data is generated. A data adjustment circuit delays the transmission data on the basis of a TAP2 value. By synchronizing the delayed transmission data with the adjusted clock signal, adjusted reception data is generated. A data adjustment control circuit generates the TAP2 value on the basis of a result of a comparison between the reception data and the adjusted reception data, and outputs to a clock adjustment control circuit an instruction to update the TAP value.
