Table 13-58. Endpoint Characteristics: Queue Head DWord 1 (continued)
Data toggle control (DTC). Specifies where the host controller should get the initial data toggle on
an overlay transition.
0 Ignore DT bit from incoming qTD. Host controller preserves DT bit in the queue head.
1 Initial data toggle comes from incoming qTD DT bit. Host controller replaces DT bit in the queue
Endpoint speed. This is the speed of the associated endpoint.
00 Full-speed (12 Mbps)
01 Low-speed (1.5 Mbps)
10 High-speed (480 Mbps)
11 Reserved, should be cleared This field must not be modified by the host controller.
Endpoint number. Selects the particular endpoint number on the device serving as the data source
or sink.
Inactivate on next transaction. This bit is used by system software to request that the host controller
set the Active bit to zero. This field is only valid when the queue head is in the periodic schedule and
the EPS field indicates a full- or low-speed endpoint. Setting this bit when the queue head is in the
asynchronous schedule or the EPS field indicates a high-speed device yields undefined results.
High-bandwidth pipe multiplier. This field is a multiplier used to key the host controller as the number
of successive packets the host controller may submit to the endpoint in the current execution. The
host controller makes the simplifying assumption that software properly initializes this field
(regardless of location of queue head in the schedules or other run time parameters).
00 Reserved, should be cleared. A zero in this field yields undefined results.
01 One transaction to be issued for this endpoint per microframe
10 Two transactions to be issued for this endpoint per microframe
11 Three transactions to be issued for this endpoint per microframe
This field is ignored by the host controller unless the EPS field indicates a full- or low-speed device.
The value is the port number identifier on the USB 2.0 hub (for hub at device address Hub Addr
below), below which the full- or low-speed device associated with this endpoint is attached. This
information is used in the split-transaction protocol.
This field is ignored by the host controller unless the EPS field indicates a full-or low-speed device.
The value is the USB device address of the USB 2.0 hub below which the full- or low-speed device
associated with this endpoint is attached. This field is used in the split-transaction protocol.
