In one cycle for transferring data, a controller forming a data transfer circuit stores pointer information P_A for periodic transfer and pointer information P_B for non-periodic transfer read from a memory respectively in first and second storage areas. The controller sequentially transfers, to a communication bus, data D_A for periodic transfer and data D_B for non-periodic transfer read from the memory by referring to the P_A and P_B. If transfer by a data length indicated in the P_B has not been completed upon the transfer of the D_B, the controller updates the data length to a data length of the remaining data, and updates an address indicated in the P_B to an address on the memory of the remaining data. In the next cycle for transferring data, the controller reads the remaining data from the memory by referring to the P_B, and transfers the remaining data to the communication bus.
