<P>PROBLEM TO BE SOLVED: To provide a transmission control circuit for communicating auto-negotiation data transparently. <P>SOLUTION: A transmission control circuit comprises: a packet data FIFO; an auto-negotiation data FIFO; a data recognition part which, in synchronization with a predetermined write clock, stores reception data in the packet data FIFO when the reception data is packet data, and stores the reception data in the auto-negotiation data FIFO when the reception data is auto-negotiation data; and a data selection part which, in synchronization with a predetermined read clock, reads out the reception data stored in either of the packet data FIFO and the auto-negotiation data FIFO, depending on the data recognition part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
