-- Note: The IEEE-1394 internal cable bundle needs an outer shield to
minimize internal crosstalk within the cable construction. The outer EMI
containment shield for the IEEE-1394 function will be provided by the
overall P&D cable shield. If the internal bundle shield for IEEE-1394 is
required, this may be terminated to pin #18. It is recommended that this
implementation be evaluated in the case where both Charge Power return
and the IEEE-1394 internal cable bundle shield will be commoned to pin
#18.
