DESCRIPTION
Reserved
Global Unicast Enable (GUE). When set, the MAC wakes up from power-saving mode on receipt of
a global unicast frame. A global unicast frame has the MAC Address [1:0] bit set to 0.

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, "LAN9118 PHY Control and Status Register"below.
Note: The NASR (Not Affected by Software Reset) designation is only applicable when bit 15 of
the PHY Basic Control Register (Reset) is set.
