Description
-
-
-
-
Active: Write the same value as that in V.
Halt: This bit corresponds to the Halt bit of the Status field of TD.
Babble: This bit corresponds to the Babble Detected bit in the
Status field of iTD, siTD or TD.
1 — When babbling is detected, A and V are set to 0.
Transaction Error: This bit corresponds to the Transaction Error
bit in the status field.
0 — Before scheduling
Start/Complete:
0 — Start split
1 — Complete split
-
Data Toggle: Set the Data Toggle bit to start for the PTD.
Error Counter: This field contains the error count for
asynchronous start and complete split (SS/CS) TD. When an
error has no response or bad response, Cerr[1:0] will be
decremented to zero and then Valid will be set to zero. A NAK or
NYET will reset Cerr[1:0]. For details, refer to Section 4.12.1.2 of
Ref. 2 “Enhanced Host Controller Interface Specification for
Universal Serial Bus Rev.
If retry has insufficient time at the beginning of a new SOF, the
first PTD must be this retry. This can be accomplished if aperiodic
PTD is not advanced.
NAK Counter: The V bit is reset if NakCnt decrements to zero
and RL is a nonzero value. Not applicable to isochronous split
transactions.
-
Number of Bytes Transferred: This field indicates the number of
bytes sent or received for this transaction.
