Description
Specifies which SOF the start split needs to be placed.
For OUT token: When the frame number of bits DW1[7:3]
matches the frame number of the USB bus, these bits are
checked for one before they are sent for the SOF.
For IN token: Only SOF0, SOF1, SOF2 or SOF3 can be set
to 1. Nothing can be set for SOF4 and above.
Active: Write the same value as that in V.
Halt: The Halt bit is set when any micro frame transfer status has
a stalled or halted condition.
Babble: This bit corresponds to bit 1 of Status0 to Status7 for
every micro frame transfer status.
Transaction Error: This bit corresponds to bit 0 of Status0 to
Status7 for every micro frame 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.
