1= something is plugged into jack associated
with Pin Complex.
Measured impedance of the widget. A value of
all 1's indicates that a valid sense reading is
not available, or the sense measurement is
busy if it has been recently triggered.
Set 1= perform impedance sensing on right
channel or ring of the connector
Set 0= perform impedance sensing on left
channel or tip of the connector
Payload
Reserved
Allow generation of Unsolicited Responses.
Unsolicited response events occur upon
jack-insertion OR completion of a
Jack-Sense cycle.
Reserved
Software programmable field returned in top
six bits (31:26) of every Unsolicited
Response generated by this node.
