4.13.4.3 Manual Wake Assertion

While powered up in the ACTIVE state, the host controller may wish to initiate a wake-up event to the network and/or additional devices. This may be accomplished by triggering a manual wake forward event by writing a ‘1’ to the Manual Wake Forward (MWKFWD) bit in the Sleep Control 1 (SLPCTL1) register. Once set, the device will initiate wake activity on the MDI if the MDI Wake Forward Enable (MDIWFWD) bit is set. Additionally, or alternatively, a high wake pulse may be initiated to the WAKE_OUT pin if the WAKE_OUT Forward Enable (WKOFWDEN) bit is set. Once the wake events have completed, the device will clear the Manual Wake Forward bit.
