Value Description

0
not applicable
-
Jump:
0 — To increment the PTD pointer.
1 — To enable the next PTD branching.
-
Next PTD Counter: Next PTD branching assigned by the PTD
pointer.
-
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.
-
Error: This bit corresponds to the Transaction Error bit in the Status
field of iTD, siTD or TD (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.
-
0 — Before scheduling.
-
-
-
Ping: For high-speed transactions, this bit corresponds to the Ping
state bit in the Status field of a TD.
0 — Ping is not set.
1 — Ping is set.
For the first time, software sets the Ping bit to 0. For the successive
asynchronous TD, software sets the bit in asynchronous TD based
on the state of the bit for the previous asynchronous TD of the same
transfer, that is:
The current asynchronous TD is completed with the Ping bit
set.
The next asynchronous TD will have its Ping bit set by the
software.
-
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.
