The HcControlCurrentED register contains the physical address of the current ED of the
control list. The bit allocation is given in
This register (see
Description
Controller must continue processing the list from where it 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 in the HcControl
register) 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.
