Halt: Transaction is halted.
-
Data Toggle: Set the Data Toggle bit to start the PTD. Software
writes the current transaction toggle value. Hardware writes the next
transaction toggle value.
Error Counter: This field corresponds to the Cerr[1:0] field in TD. The
default value of this field is zero for isochronous transactions.
-
Number of Bytes Transferred: This field indicates the number of
bytes sent or received for this transaction. If Mult[1:0] is greater than
one, it is possible to store intermediate results in this field.
-
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 direct CPU address.
RAM address = (CPU address
Bits 7 to 3 represent the polling rate in milliseconds.
The INT polling rate is defined as 2
When b is 1, 2, 3 or 4, use SA to define polling because the rate is
equal to or less than 1 ms. Bits 7 to 3 are set to 0. Polling checks SA
bits for SOF rates. See
-
This bit indicates if a split transaction has to be executed:
0 — High-speed transaction
1 — Split transaction
Endpoint type:
11 — Interrupt
Token: This field indicates the token PID for this transaction:
00 — OUT
01 — IN
Device Address: This is the USB address of the function containing
the endpoint that is referred to by the buffer.
Endpoint: This is the USB address of the endpoint within the
function.
Endpoint: This is the USB address of the endpoint within the
function.
Multiplier: This field is a multiplier counter used by the Host
Controller as the number of successive packets the Host Controller
may submit to the endpoint in the current execution.
Set this field to 01b. You can also set it to 11b and 10b depending on
your application. 00b is undefined.
