1 = something is plugged into jack associated with Pin
Complex.
Measured impedance of the widget. A value of all 1
indicates that a valid sense reading is not available, or
the sense measurement is busy if it has been recently
triggered. Overlaps RightCh.
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
