Resets

Power-on Reset (internal): The 82575EB has an internal mechanism for sensing the power pins.

Once the power is up and stable, it creates an internal reset, this reset acts as a master reset of the

entire chip. It is level sensitive, and while it is 0, will hold all of the registers in reset. Power-on Reset

is interpreted to be an indication that device power supplies are all stable. Power-on Reset changes

state during system power-up.

In-band PCIe Reset: The 82575EB will generate an internal reset in response to a physical layer

message from the PCIe or when the PCIe link halts (entry to Polling or Detect state). This reset is

equivalent to PCI reset in previous (PCI) gigabit LAN controllers.

Main_Power_Good: Used by the device to detect the D3Cold condition and activate part of the power

saving scheme.
