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.

Note:

The NASR (Not Affected by Software Reset) designation is only applicable when bit 15 of the PHY Basic

Control Register (Reset) is set.
