Description
the current ED. The Host Controller needs to continue processing the list
from where it was left in the last frame. When it reaches the end of the
control list, the Host Controller checks CLF (bit 1 of HcCommandStatus). If
set, it copies the content of HcControlHeadED to HcControlCurrentED and
clears the bit. If not set, it does nothing. The HCD is allowed to modify this
register only when CLE (bit 4 of HcControl) is cleared. When set, the HCD
only reads the instantaneous value of this register. Initially, this is set to
logic 0 to indicate the end of the control list.
