zero in this field selects Page 0 and a one selects Page 1. During the start-split for an OUT, if the data
transfer crosses a page boundary during the transaction, the host controller must detect the page cross,
update the siTD [P] bit from a zero to a one, and begin using the siTD Page 1 with siTD [Current Offset]
as the memory address pointer. The field siTD [TP] is used to annotate each start-split transaction with the
indication of which part of the split-transaction data the current payload represents (ALL, BEGIN, MID,
END). In all cases, the host controller simply uses the value in siTD [TP] to mark the start-split with the
correct transaction position code.
T-Count is always initialized to the number of start-splits for the current frame. TP is always initialized to
the first required transaction position identifier. The scheduling boundary case (see
determines the initial value of TP. The initial cases are summarized in
After each start-split transaction is complete, the host controller updates T-Count and TP appropriately so
that the next start-split is correctly annotated.
which must be accomplished by the host controller.
The start-split transactions do not receive a handshake from the transaction translator, so the host controller
always advances the transfer state in the siTD after the bus transaction is complete. To advance the transfer
state, the following operations take place:
These fields are then written back to the memory based siTD. The S-mask is fixed for the life of the current
budget. As mentioned above, TP and T-count are set specifically in each siTD to reflect the data sent from

When the OUT data payload is less than (or equal to) 188 bytes, only one start-split is
required to move the data. The one start-split must be marked with an ALL.
When the OUT data payload is greater than 188 bytes more than one start-split must be
used to move the data. The initial start-split must be marked with a BEGIN.
Transition from ALL, to done.
Transition from BEGIN to END. Occurs when T-count starts at 2.
Transition from BEGIN to MID. Occurs when T-count starts at greater than 2.
TP stays at MID while T-count is not equal to 1 (for example, greater than 1). This case
can occur for any of the scheduling boundary cases where the T-count starts greater
than 3.
Transition from MID to END. This case can occur for any of the scheduling boundary
cases where the T-count starts greater than 2.
