1
Wake enable for GPIO1: 0 = wake-up event is disabled; 1 = When HD Audio
link is powered down (RST# is asserted), a wake-up event will trigger a Status
Change Request event on the link.
0
Wake enable for GPIO0: 0 = wake-up event is disabled; 1 = When HD Audio
link is powered down (RST# is asserted), a wake-up event will trigger a Status
Change Request event on the link.

Reserved.
4
Unsolicited enable mask for GPIO4. If set, and the Unsolicited Response con-
trol for this widget has been enabled, an unsolicited response will be sent when
GPIO2 is configured as input and changes state. (Available only on 48-pin ver-
sions)
3
Unsolicited enable mask for GPIO3. If set, and the Unsolicited Response con-
trol for this widget has been enabled, an unsolicited response will be sent when
GPIO2 is configured as input and changes state.
2
Unsolicited enable mask for GPIO2. If set, and the Unsolicited Response con-
trol for this widget has been enabled, an unsolicited response will be sent when
GPIO2 is configured as input and changes state.
1
Unsolicited enable mask for GPIO1. If set, and the Unsolicited Response con-
trol for this widget has been enabled, an unsolicited response will be sent when
GPIO1 is configured as input and changes state.
