Wake capability. Assuming the Wake Enable Mask controls are
enabled, GPIO's configured as inputs can cause a wake
(generate a Status Change event on the link) when there is a
change in level on the pin.
Unsolicited Response capability. Assuming the Unsolicited
Enable Mask controls are enabled, GPIO's configured as inputs
can generate an Unsolicited Response on the link when there is a
change in level on the pin.
