Description
General TD or isochronous data packet processing
completed with no detected errors.
Last data packet from endpoint contained a CRC error.
Last data packet from endpoint contained a bit stuffing
violation.
Last packet from endpoint had data toggle PID that did
not match the expected value.
TD was moved to the Done queue because the
endpoint returned a STALL PID.
Device did not respond to token (IN) or did not provide a
handshake (OUT).
Check bits on PID from endpoint failed on data PID (IN)
or handshake (OUT)
Received PID was not valid when encountered or PID
value is not defined.
The amount of data returned by the endpoint exceeded
either the size of the maximum data packet allowed
from the endpoint (found in MaximumPacketSize field of
ED) or the remaining buffer size.
The endpoint returned is less than MaximumPacketSize
and that amount was not sufficient to fill the specified
buffer.

During an IN, the HC received data from an endpoint
faster than it could be written to system memory.
During an OUT, the HC could not retrieve data from the
system memory fast enough to keep up with the USB
data rate.

R/W
Set to logic 1 by firmware 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.
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.
The maximum number of bytes that can be sent to or received from the endpoint in a
single data packet.
USB address of the endpoint within the function.
Last PTD of a list (ITL or ATL). A logic 1 indicates that the PTD is the last PTD.

S = 0 —
