Abstract
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.
