Field name
TMPA901CM- 781
This bit is used to indicate whether there are any TDs on the Bulk list. It
is set by HCD whenever it adds a TD to an ED in the Bulk list.
When the HC begins to process the head of the Bulk list, it checks BF.
As long as BulkListFilled is 0, the HC will not start processing the Bulk
list. If BulkListFilled is 1, the HC will start processing the Bulk list and
will set BF to 0. If the HC finds a TD on the list, then the HC will set
BulkListFilled to 1 causing the Bulk list processing to continue. If no TD
is found on the Bulk list, and if HCD does not set BulkListFilled, then
BulkListFilled will still be 0 when the HC completes processing the
Bulk list and Bulk list processing will stop.
This bit is used to indicate whether there are any TDs on the Control
list. This is set by HCD whenever it adds a TD to an ED in the Control
list.
When the HC begins to process the head of the Control list, it checks
CLF. As long as ControlListFilled is 0, the HC will not start processing
the Control list. If CF is 1, the HC will start processing the Control list
and will set ControlListFilled to 0. If the HC finds a TD on the list, then
the HC will set ControlListFilled to 1 causing the Control list processing
to continue. If no TD is found on the Control list, and if HCD does not
set ControlListFilled, then ControlListFilled will still be 0 when the HC
completes processing the Control list and Control list processing will
stop.
This bit is set by HCD to initiate a software reset of the HC. Regardless
of the functional state of the HC, it moves to the UsbSuspend state in
which most of the operational registers are reset except those stated
otherwise; e.g., the InterruptRouting field of HcControl, and no host
bus accesses are allowed. This bit is cleared by the HC upon
completion of the reset operation. The reset operation must be
completed within 10 μs. This bit, when set, should not cause a reset to
the Root Hub and no subsequent reset signaling should be asserted to
its downstream ports.
