Abstract
In a multiplex transmission apparatus and a multiplex transmission method when a control unit reads reception data while a status flag is set, it determines that the reception data is obtained before data in a transmission buffer is transmitted. When the control unit reads the reception data while the status flag is reset, it determines that the read data is response data to transmission data. Thus, the control unit precisely recognizes the time series of data on communication control.
