Word "can" suggests > you are documenting something which exists, but this does not exist. Can you elaborate a bit more on the "not existing" part please? For the WoL from PHY to be supported, the PHY line that is raised (On nPME pin for this case) when receiving a wake up event has to be wired to a wakeup event input of the Extended interrupt and event controller(EXTI), and that's implementation dependent.
