4.GD82559ER Media Access Control Functional Description

4.182559ER Initialization

The 82559ER has four sources for initialization. They are listed according to their precedence:

1.ALTRST# Signal

2.PCI RST# Signal

3.Software Reset (Software Command)

4.Selective Reset (Software Command)

4.1.1Initialization Effects on 82559ER Units

The following table shows the effect of each of the different initialization sources on major portions of the 82559ER. The initialization sources are listed in order of precedence. For example, any resource that is initialized by the Software Reset is also initialized by the D3 to D0 transition and ALTRST# and PCI RST# but not necessarily by the selective reset.
