PeriodCurrentED. This is used by HC to point to the head
of one of the Periodic lists which will be processed in the
current Frame. The content of this register is updated by
HC after a periodic ED has been processed. HCD may
read the content in determining which ED is currently
being processed at the time of reading.
Reserved. Unknown During Read.
ControlHeadED. HC traverses the Control list starting with
the HcControlHeadED pointer. The content is loaded from
HCCA during the initialization of HC.
