Halt
: This bit correspond to the Halt bit of the Status field of QH.
Babble
: This bit correspond to the Babble Detected bit in the Status
field of the iTD, SiTD or QH.
1 —
When babbling is detected, A and V are set to 0.
Error
: This bit corresponds to the Transaction Error bit in the Status
field of iTD, SiTD or QH (Exec_Trans, the signal name is xacterr).
0 —
No PID error.
1 —
If there are PID errors, this bit is set active. The A and V bits are
also set to inactive. This transaction is retried three times.
-
Ping
: For high-speed transactions, this bit corresponds to the Ping
state bit in the Status field of a QH.
0 —
Ping is not set.
1 —
Ping is set.
Software sets this bit to 0.
Data Toggle
: This bit is filled by software to start a PTD. If
NrBytesToTransfer[14:0] is not complete, software needs to read this
value and then write back the same value to continue.
Error Counter
. This field corresponds to the Cerr[1:0] field in QH. The
default value of this field is zero for isochronous transactions.
00 —
The transaction will not retry.
11 —
The transaction will retry three times. Hardware will decrement
these values. When the transaction has tried three times, X error will
be updated.
NAK Counter
. This field corresponds to the NakCnt field in QH.
Software writes for the initial PTD launch. The V bit is reset if NakCnt
decrements to zero and RL is a non-zero value. It reloads from RL if
transaction is ACKed.
