6.9.1 Power States
s
DO (Fully On)
In this state the STE10/100A operates with full functionality and consumes normal power. While in the
D0 state, if the PCI clock is lower than 16MHz, the STE10/100A may not receive or transmit frames
properly.
s
D1, D2, and D3hot
In these states, the STE10/100A doesn’t respond to any accesses except configuration space and full
function context in place. The only network operation the STE10/100A can initiate is a wake-up event.
s
D3cold (Power Removed)
In this state all function context is lost. When power is restored, a PCI reset must be asserted and the
function will return to D0.
s
D3hot (Software Visible D3)
When the STE10/100A is brought back to D0 from D3hot the software must perform a full initialization.
The STE10/100A in the D3hot state responds to configuration cycles as long as power and clock are
supplied. This requires the device to perform an internal reset and return to a power-up reset condition
without the RST# pin asserted.
