TSE+marvell88E1111 without Nious

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?
