Description
-
Port Number: This indicates the port number of the hub or
embedded TT.
-
This depends on the endpoint type and direction. It is valid only for
split transactions.
only.
-
-
-
This bit indicates whether a split transaction has to be executed:
0 — High-speed transaction
1 — Split transaction
-
Transaction type:
11 — Interrupt
-
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 this 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.
-
-
-
Maximum Packet Length: This field indicates the maximum
number of bytes that can be sent to or received from an endpoint in
a single data packet. The maximum packet size for the full-speed
and low-speed devices is 64 bytes as defined in
Serial Bus Specification Rev.
-
Number of Bytes to Transfer: This field indicates the number of
bytes that can be transferred by this data structure. It is used to
indicate the depth of the DATA field. The maximum total number of
bytes for this transaction is 4 kB.
-
-
-
0 — This bit is deactivated when the entire PTD is executed, or
when a fatal error is encountered.
1 — Software updates to one when there is payload to be sent or
received. The current PTD is active.
