16.5.4
All full-speed isochronous transfers through the internal transaction translator are managed using the siTD
data structure. This data structure satisfies the operational requirements for managing the split transaction
protocol.
16.5.4.1
DWord0 of a siTD is a pointer to the next schedule data structure.
16.5.4.2
DWords 1 and 2 specify static information about the full-speed endpoint, the addressing of the parent
Companion Controller, and micro-frame scheduling control.

Figure 16-39. Split-Transaction Isochronous Transaction Descriptor (siTD)
This field contains the address of the next data object to be processed in the periodic list and
corresponds to memory address signals [31:5], respectively.
Reserved, should be cleared. These bits must be written as zeros.
Indicates to the host controller whether the item referenced is an iTD/siTD or a QH. This allows the host
controller to perform the proper type of processing on the item after it is fetched. Value encodings are:
00 iTD (isochronous transfer descriptor)
01 QH (queue head)
10 siTD (split transaction isochronous transfer descriptor
11 FSTN (frame span traversal node)
Terminate.
0 Link pointer is valid.
