82559 Media Access Control Functional Description
4.1
82559 Initialization
The 82559 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)
4.1.1
Initialization Effects on 82559 Units
The following table shows the effect of each of the different initialization sources on major portions
of the 82559. 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.
