a. Typical conditions are T_A = 25 C, voltages are nominal. Where applicable, network traffic is moderate at full duplex and the
system interface is PCI 66 MHz.
b. Maximum conditions are T_A = minimum, voltages are maximum. Where applicable, network traffic is continuous at full duplex
and the system interface is PCI-X 100 to 133 MHz.
c. In the powerdown mode, the controller is in the D3_hot state, with PME# wake-up enabled. Link is present at 100 Mbps.
d. In the quiescent mode, the controller is in the D3_cold state, with wake-up disabled. Link is not present.
