Next Transfer Element Pointer. This field contains the physical memory address of the next dTD to be
processed. The field corresponds to memory address signals [31:5], respectively.
Reserved. Bits reserved for future use and should be set to 0.
Terminate (T). 1=pointer is invalid. 0=Pointer is valid (points to a valid Transfer Element Descriptor). This bit
indicates to the device controller that no more valid entries exist in the queue.
Reserved. Bit reserved for future use and should be set to 0.
Total Bytes. This field specifies the total number of bytes to be moved with this transfer descriptor. This field is
decremented by the number of bytes actually moved during the transaction and only on the successful
completion of the transaction.
The maximum value software may store in the field is 5 × 4 KB (0x5000). This is the maximum number of bytes
5 page pointers can access. Although it is possible to create a transfer as large as 20 KB this assumes the first
offset into the first page is 0. When the offset cannot be predetermined, crossing passed the fifth page can be
guaranteed by limiting the total bytes to 16 KB. Therefore, the maximum recommended transfer is
16 KB (0x4000).
If the value of the field is 0 when the host controller fetches this transfer descriptor (and the active bit is set),
the device controller executes a zero-length transaction and retires the transfer descriptor.
It is not a requirement for IN transfers that total bytes to transfer be an even multiple of maximum packet length.
If software builds such a transfer descriptor for an IN transfer, the last transaction is always less that maximum
packet length.
Interrupt On Complete (IOC). This bit indicates if USBINT is to be set in response to device controller being
finished with this dTD.
Reserved. Bits reserved for future use and should be set to 0.
Multiplier Override (MultO). This field can be used for transmit ISO's (i.e., ISO-IN) to override the multiplier in
the QH. This field must be zero for all packet types that are not transmit-ISO.
Example:
if QH.multiplier = 3; Maximum packet size = 8; Total Bytes = 15; MultiO = 0 [default]
Three packets are sent: {Data2(8); Data1(7); Data0(0)}
if QH.multiplier = 3; Maximum packet size = 8; Total Bytes = 15; MultiO = 2
Two packets are sent: {Data1(8); Data0(7)}
For maximal efficiency, software should compute MultO = greatest integer of (Total Bytes/Max. Packet Size)
except for the case when Total Bytes = 0; then MultO should be 1.
Note: Non-ISO and Non-TX endpoints must set MultO = 00.
