I need an access to PHY/PCS registers of Xeon D1500 10GbE LAN. For 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 is 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 220.127.116.11.1 "PHY Indirect Data" and 18.104.22.168.2 "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?
