Description
GPIWake
Wake capability. Assuming the Wake Enable Mask controls are
R
0x1
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.
GPIUnsol
Unsolicited Response capability. Assuming the Unsolicited
R
0x1
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.
