HI,everybody! 

I'm using the TSE mac and marvell 88E1111 to design an ethernet interface without Nious.Now,I have finished configurating the MAC and it can transceiver data correctly.However, when I want connect the MAC to PHY there is a problem:the MAC should manage the PHY by MDIO interface which is a two-wire interface on the PHY(MDIO and MDC) but the MAC have four-wire(mdio_in、mdio_out、mdio_oeN and mdc).Does anybody know how to figure out this problem?

Hi 

you can use mdio_in、mdio_out and mdio_oeN to control mdio in FPGA,refer to the TSE mac core for details

Thank you for your reply,Titan.I've read the tse mac user guide.There is only a block diagram to illustrate how to combine mdio_in、mdio_out and mdio_oeN to control the mdio.Can you give me some information in detail how to combine these three signals?
