PCI Power Management

The integrated GbE controller supports the Advanced Configuration and Power Interface (ACPI) specification as well as Advanced Power Management (APM). This enables the network-related activity (using an internal host wake signal) to wake up the host. For example, from Sx (S5) and Deep Sx to S0.

Note:The Intel® Ethernet Connection I219 must be powered during the Deep Sx state in order to support host wake up from Deep Sx. LAN_​WAKE# on the PCH must be configured to support wake from Deep Sx and must be connected to LANWAKE# on the Platform LAN Connect Device. The SLP_​LAN# signal must be driven high (de-asserted) in the Deep Sx state to maintain power to the Platform LAN Connect Device.

The integrated GbE controller contains power management registers for PCI and supports D0 and D3 states. PCIe* transactions are only allowed in the D0 state, except for host accesses to the integrated GbE controller’s PCI configuration registers.

Note:SLP_​LAN# pin behavior are detailed in SLP_​LAN# Pin Behavior
