Description
the present. The Host Controller must continue processing the list from
where it left off in the last frame. When it reaches the end of the control list,
the Host Controller checks the CLF (Control List Filled) bit 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 the CLE (Control List
Enable) bit 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.
