摘要： A novel multi-port network transceiver having an LED interface supporting parallel and serial LED modes. The LED interface has a pair of LED pins for each port. In the parallel LED mode, one pin of this pair represents status of a 10 Mb/s communication, whereas another pin represents status of a 100 Mb/s communication. In the serial LED mode, status information for all ports is transferred using 3 pins supplying a serial data stream, a frame signal and 2 clock signal. The serial data stream is composed of frames, each of which represents various events for the multiple ports. The frame signal is used to identify the boundary between the frames. The transfer of the serial data stream is synchronous to the clock signal.

摘要： A novel network transceiver having a Media Independent Interface (MII) operating at 10 Mb/s or 100 Mb/s for connecting the transceiver to a repeater or hub device. A serial interface select signal can be asserted to configure the MII to operate as a General Purpose Serial Interface (GPSI) for 10 Mb/s data. The least significant transmit and receive data pins of the MII are respectively mapped to transmit and receive data pins of the GPSI. A circuit for enabling MII to operate in a GPSI mode has a transmit multiplexer controlled by the serial interface select signal to bypass a parallel-to-serial converter that transforms parallel transmit MII data into a serial data stream, and a receive multiplexer controlled by the serial interface select signal to bypass a serial-to-parallel converter that transforms serial receive data stream into parallel receive MII data.
