WakeEvent contains enable bits to control which types of events can generate a wake event to the host

system. It also contains status bits indicating the specific events that have occurred.

BIT BIT NAME BIT DESCRIPTION

0 WakePktEnable Setting this read/write bit enables the ST201 to generate wake events

via a PCI interrupt due to Wake Packet reception. PmeEn must be set

in the PowerMgmtCtrl register in order for WakePktEnable to be recog-

nized. WakePktEnable has no effect in power mode D0.

1 MagicPktEnable Setting this read/write bit enables the ST201 to generate wake events

via a PCI interrupt due to Magic Packet reception. MagicPktEnable is

set after a ST201 reset. PmeEn must be set in the PowerMgmtCtrl reg-

ister in order for MagicPktEnable to be recognized. MagicPktEnable

has no effect in power mode D0.

2 LinkEventEnable Setting this read/write bit enables the ST201 to generate wake events

via a PCI interrupt due to a change in link status (cable connect or dis-

connect). PmeEn must be set in the PowerMgmtCtrl register in order

for LinkEventEnable to be recognized. LinkEventEnable has no effect

in power mode D0.

3 WakePolarity Setting this read/write bit will cause the Wake pin to be asserted in the

HIGH state (default after RESET). MagicPktEnable is set after a

ST201 reset.

4 WakePktEvent Indicates that a wake packet (which meets the reception criteria set by

driver) has been received. WakePktEvent is masked by WakePktEna-

ble, and must be set for WakePktEvent to operate. WakePktEvent is

cleared when the WakeEvent register is read.

5 MagicPktEvent Indicates that a magic packet has been received. MagicPktEvent is

masked by MagicPktEnable, and must be set for MagicPktEvent to

operate. MagicPktEvent is cleared when the WakeEvent register is

read.

6 LinkEvent Indicates that a link status event has occurred. LinkEvent is masked by

LinkEventEnable, and must be set for LinkEvent to operate. LinkEvent

is cleared when the WakeEvent register is read.

7 WakeOnLanEnable Setting this read/write bit puts the ST201 in the WakeOnLan mode

regardless of the power management register settings in the configura-

tion space.
