PHY Registers

The PHY registers are not memory mapped. These registers are accessed indirectly through the MAC

via the MII_ACC and MII_DATA registers. An index must be used to access individual PHY registers.

PHY Register Indexes are shown in Table 5.8, "LAN9211 PHY Control and Status Register".

Note: The NASR (Not Affected by Software Reset) designation is only applicable when bit 15 of

the PHY Basic Control Register (Reset) is set.
