CompletionCode[3:0]
R/W
0000
NoError
General TD or Isochronous data packet processing
completed with no detected errors.
0001
CRC
Last data packet from endpoint contained a CRC error.
0010
BitStufng
Last data packet from endpoint contained a bit stufng
violation.
0011
DataToggleMismatch
Last packet from endpoint had data toggle PID that did
not match the expected value.
0100
Stall
TD was moved to the Done queue because the
endpoint returned a STALL PID.
0101
DeviceNotResponding
Device did not respond to token (IN) or did not provide a
handshake (OUT).
0110
PIDCheckFailure
Check bits on PID from endpoint failed on data PID (IN)
or handshake (OUT).
0111
UnexpectedPID
Received PID was not valid when encountered or PID
value is not dened.
1000
DataOverrun
The amount of data returned by the endpoint exceeded
either the size of the maximum data packet allowed
from the endpoint (found in MaximumPacketSize eld
of ED) or the remaining buffer size.
1001
DataUnderrun
The endpoint returned is less than MaximumPacketSize
and that amount was not sufcient to ll the specied
buffer.

1100
BufferOverrun
During an IN, the HC received data from an endpoint
faster than it could be written to system memory.
1101
BufferUnderrun
During an OUT, the HC could not retrieve data from the
system memory fast enough to keep up with the USB
data rate.
Active
R/W
Set to logic 1 by rmware to enable the execution of transactions by the HC. When the
transaction associated with this descriptor is completed, the HC sets this bit to logic 0,
indicating that a transaction for this element should not be executed when it is next
encountered in the schedule.
Toggle
R/W
Used to generate or compare the data PID value (DATA0 or DATA1). It is updated after
each successful transmission or reception of a data packet.
MaxPacketSize[9:0]
R
The maximum number of bytes that can be sent to or received from the endpoint in a
single data packet.
EndpointNumber[3:0]
R
USB address of the endpoint within the function.
Last (PTD)
R
Last PTD of a list (ITL or ATL). A logic 1 indicates that the PTD is the last PTD.
(Low) Speed
R
Speed of the endpoint:
S = 0 — full speed
S = 1 — low speed
TotalBytes[9:0]
R
Species the total number of bytes to be transferred with this data structure. For Bulk and
Control only, this can be greater than MaximumPacketSize.
