Description
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 the QH. 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 the 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 for ms-based polling.
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.
-
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.
