Description

BCED[27:0]
Bulk Current ED: This is advanced to the next ED after the host controller has served the current
ED. 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 CLF (bit 1 of HcCommandStatus). 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 modify this register only when BLE
(bit 5 in the HcControl register) is cleared. When HcControl is set, the HCD reads the
instantaneous value of this register. This is initially set to logic 0 to indicate the end of the bulk list.

11.1.13 HcDoneHead register
The HcDoneHead register contains the physical address of the last completed TD that
was added to the done queue. In a normal operation, the HCD need not read this register
because its content is periodically written to the HCCA.
Table 67 contains the bit allocation of the register.
