An interface test can be performed by, for example, only a self apparatus when interface operation specifications are different between the self apparatus and an original connection partner apparatus. An LSI has a plurality of interfaces (IFs) for transmission/reception of data with an external device, and the LSI includes an emulation control unit for allowing one of the two of the plurality of IFs to perform an operation of emulating an IF of a connection partner device having operation specifications different from those of the LSI, when two Ifs are connected each other via a transmission line.
