Description
GPIWake
R
Wake capability. Assuming the Wake
Enable Mask controls are enabled, GPIO's
0x1
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
R
Unsolicited Response capability. Assuming
the Unsolicited Enable Mask controls are
0x1
enabled, GPIO's configured as inputs can
generate an Unsolicited Response on the
link when there is a change in level on the
pin.
