Virtual PHY
This section details the Virtual PHY System CSR’s. These registers provide status and control
information similar to that of a real PHY while maintaining IEEE 802.3 compatibility. The Virtual PHY
registers are addressable via the memory map, as described in
MII management protocol (IEEE 802.3 clause 22). When accessed serially, these registers are
accessed indirectly through the
Data Register (HMAC_MII_DATA)
clause 22. When being accessed serially, the Virtual PHY will respond when the PHY address equals
the address assigned by the phy_addr_sel_strap configuration strap, as defined in
Addressing," on page

Virtual PHY functionality and operation information, see
Note: All Virtual PHY registers follow the IEEE 802.3 (clause 22.2.4) specified MII management
Note: When serially accessed, the Virtual PHY registers are only 16-bits wide, as is standard for MII

register set. All functionality and bit definitions comply with these standards. The IEEE 802.3
specified register index (in decimal) is included under the LAN9311/LAN9311i memory mapped
offset of each Virtual PHY register as a reference. For additional information, refer to the IEEE
802.3 Specification.
