    Intel Xeon D1500 10GbE LAN configuration - PHY/PCS registers

    RWM

      Hi,

       

      for Intel Xeon D1500 family I found only 4 datasheets, in one of them, https://www.intel.com/content/www/us/en/processors/xeon/xeon-d-1500-datasheet-vol-4.html there are some information about LAN configuration, but not enough. I need access to PHY/PCS registers of 10GbE interfaces. There is a link to Appendix B, but there is no register map or other access mode (like MDIO). There is also chapter 8.2.2.11.1 "PHY Indirect Data" and 8.2.2.11.2 "PHY Indirect Control" but there is no explanation what is "16bit address" and no information how to access certain PHY registers. Is there available any other document which describes PHY/PCS registers and access method?

       

      Best regards,
