44 / 103 page  Micrel, Inc. KSZ8873MLL/FLL/RLL September 2009 44 M9999-092309-1.2 MII Management (MIIM) Registers The MIIM interface is used to access the MII PHY registers defined in this section. The SPI, I 2C, and SMI interfaces can also be used to access some of these registers. The latter three interfaces use a different mapping mechanism than the MIIM interface. The “PHYADs” by defaults are assigned “0x1” for PHY1 (port 1) and “0x2” for PHY2 (port 2). Additionally, these “PHYADs” can be programmed to the PHY addresses specified in bits[7:3] of Register 15 (0x0F): Global Control 13. The “REGAD” supported are 0x0-0x5, 0x1D and 0x1F. Register Number Description PHYAD = 0x1, REGAD = 0x0 PHY1 Basic Control Register PHYAD = 0x1, REGAD = 0x1 PHY1 Basic Status Register PHYAD = 0x1, REGAD = 0x2 PHY1 Physical Identifier I PHYAD = 0x1, REGAD = 0x3 PHY1 Physical Identifier II PHYAD = 0x1, REGAD = 0x4 PHY1 Auto-Negotiation Advertisement Register PHYAD = 0x1, REGAD = 0x5 PHY1 Auto-Negotiation Link Partner Ability Register PHYAD = 0x1, 0x6 – 0x1C PHY1 Not supported PHYAD = 0x1, 0x1D PHY1 Not supported PHYAD = 0x1, 0x1E PHY1 Not supported PHYAD = 0x1, 0x1F PHY1 Special Control/Status PHYAD = 0x2, REGAD = 0x0 PHY2 Basic Control Register PHYAD = 0x2, REGAD = 0x1 PHY2 Basic Status Register PHYAD = 0x2, REGAD = 0x2 PHY2 Physical Identifier I PHYAD = 0x2, REGAD = 0x3 PHY2 Physical Identifier II PHYAD = 0x2, REGAD = 0x4 PHY2 Auto-Negotiation Advertisement Register PHYAD = 0x2, REGAD = 0x5 PHY2 Auto-Negotiation Link Partner Ability Register PHYAD = 0x2, 0x6 – 0x1C PHY2 Not supported PHYAD = 0x2, 0x1D PHY2 LinkMD Control/Status PHYAD = 0x2, 0x1E PHY2 Not supported PHYAD = 0x2, 0x1F PHY2 Special Control/Status |
