6.7.4.4 Wake on LAN
The packet classification engine can use the WAKE action to signal the host to come out of power down
mode. This is used to implement the Wake-On-LAN feature.
The Power Management Control and Status Register (PMCSR) is used to control the hardware response
to a WAKE action. If the PS field of the PMCSR is zero then all WAKE actions are ignored. The
WAKE action is only honored if the part is currently in a power down mode as determined by the
PS field. If the PME_ENB bit in the PMCSR is set then a valid WAKE action will trigger the assertion of
the PMEB primary output. If the PME_ENB bit is clear then a valid WAKE action will only result in the
normal HIR WAKE interrupt.
When the host is notified of a valid WAKE event, either by the assertion of the PMEB primary output or
assertion of INTB via the WAKE HIR interrupt, the rule that triggered the event can be read from the
Wake Up Status Register (WUSR). A valid WAKE event will also start the Host Not Responding (HNR)
timer. When the host is notified of a WAKE event, it must clear the event by setting the PME bit in the
