HcDoneHead register (address: value read from func0 or func1 of address
10H
+
30H)
The HcDoneHead register contains the physical address of the last completed TD
that was added to the Done queue. In normal operation, the HCD does not need to
read this register as its content is periodically written to the HCCA.
Table 66
contains
the bit allocation of the register.

Description
BCED[27:0]
BulkCurrentED
: This is advanced to the next ED after the Host
Controller has served the present one. The Host Controller
continues processing the list from where it left off in the last
frame. When it reaches the end of the Bulk list, the Host
Controller checks the CLF (ControlListFilled) bit of HcControl. If
the CLF bit is not set, nothing is done. If the CLF bit is set, it
copies the content of HcBulkHeadED to HcBulkCurrentED and
clears the CLF bit. The HCD can only modify this register when
the BLE (BulkListEnable) bit of HcControl is cleared. When
HcControl is set, the HCD reads the instantaneous value of this
register. This is initially set to 0 to indicate the end of the Bulk list.
