AN983B Datasheet, PDF (74/91 Pages) List of Unclassifed Manufacturers – PCI/miniPCI-to-Ethernet LAN Controller

AN983B PCI/miPCI Fast Ethernet Controller with integrated PHY
Compatibility with PCI CLKRUN scheme.
8.9.1 POWER STATES
DO (Fully On)
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.
D1
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.
D2
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.
D3_cold (Power Removed)
In this state all function context is lost. When power is restored, the function will return to D0.
D3_hot (Software Visible D3)
When the AN983B is brought back to D0 from D3_hot the software must perform a full
initialization.
The AN983B in the D3_hot state respond to configurations 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.
