marvell 88E6085 pdf 原版资料： The MII MAC Mode, sometimes called ‘Forward MII’, configures Port 9 or Port 10’s MAC inside the device to act as a MAC so it can be directly connected to an external MII-based PHY. In this mode, the device receives the interface clocks (Px_TXCLK and Px_RXCLK) from the PHY and will work at any frequency from DC to 25 MHz. The two clocks can be asynchronous with each other. Both full- and half-duplex modes are supported and need to be selected to match the mode of the link partner’s MAC. The MII MAC mode is compliant with IEEE 802.3 clause 22.
