Description
[31]
GPIWake
R
0x1
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.
[30]
GPIUnsol
R
0x1
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.
