Description
Active: Write the same value as that in V.
Halt: The Halt bit is set when any microframe transfer status has a
stalled or halted condition.
Babble: This bit corresponds to bit 1 of Status0 to Status7 for every
microframe transfer status.
Transaction Error: This bit corresponds to bit 0 of Status0 to Status7
for every microframe transfer status.
Start/Complete:
0 — Start split
1 — Complete split.
-
Data Toggle: For an interrupt transfer, set correct bit to start the PTD.
Error Counter. This field corresponds to the Cerr[1:0] field in QH.
00 — The transaction will not retry.
11 — The transaction will retry three times. Hardware will decrement
these values. When the transaction has tried three times, X error will be
updated.
-
Number of Bytes Transferred: This field indicates the number of
bytes sent or received for this transaction.
-
Data Start Address: This is the start address for the data that will be
sent or received on or from the USB bus. This is the internal memory
address and not the CPU address.
Bits 7 to 3 is the ms polling rate. Polling rate is defined as 2
where b = 4 to 16. When b is 4, every ms is executed.

Hub Address: This indicates the hub address. Zero for the internal or
embedded hub.
Port Number: This indicates the port number of the hub or embedded
TT.
