8.9.1 POWER STATES
In this state the AN983B operates as full functionality and consumes its normal power. While
in the D0 state, if the PCI clock is lower than 16MHz, the AN983B may not receive or
transmit frames properly.
In this state the AN983B doesn’t response to any accesses, except configuration space and
full function context in place. The only network operation the AN983B can initiate is a
wake-up event.
In this state the AN983B only respond to access configuration space and full function context
in place. The AN983B can’t transmit or receive even the wake-up frame.
In this state all function context is lost. When power is restored, the function will return to D0.
When the AN983B is brought back to D0 from D3
initialization.
The AN983B in the D3
are supplied. This requires the device to perform an internal reset and return to a power-up
reset condition without the RST# pin asserted.
