HcControlCurrentED register: bit description

Description
CCED[27:0]
ControlCurrentED
: This pointer is advanced to the next ED after
serving the present one. The Host Controller needs to 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 (ControlListFilled) 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 (ControlListEnable) 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.
