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 TD.
00 — The transaction will not retry.
11 — The transaction will retry three times. Hardware will decrement
these values.
-
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 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 polling rate in milliseconds. Polling rate is defined as
2
millisecond. See
Hub Address: This indicates the hub address.
Port Number: This indicates the port number of the hub or
embedded TT.
This depends on the endpoint type and direction. It is valid only for split
transactions.
-
This bit indicates whether a split transaction has to be executed:
0 — High-speed transaction
1 — Split transaction
Transaction type:
11 — Interrupt
