31:0 | LINK | R | 0h | MDIO Link state. This register is updated after a read of the Generic Status Register of a PHY. The corresponding bit is set if the PHY with the corresponding address has link and the PHY acknowledges the read transaction. The bit is cleared to zero if the PHY indicates it does not have link or fails to acknowledge the read transaction. Writes to the register have no effect. In addition, in Normal Mode Operation, the status of the two PHYs specified in the MDIOUserPhySel registers can be determined using the MLINK input pins. This is determined by the linksel bit in the MDIOUserPhySel register. In State Change Mode the MLINK input pins are unused. |
