Number of Bytes Transferred: This field indicates the number of
bytes sent or received for this transaction.
-
Reload: If RL is set to 0h, hardware ignores the NakCnt value. Set
RL and NakCnt to the same value before a transaction. For
full-speed and low-speed transactions, set this field to 0000b. Not
applicable to isochronous start split and complete split.
-
Data Start Address: This is the start address for 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
-
Hub Address: This indicates the hub address.
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
Endpoint Type:
00 — Control
10 — Bulk
Token: This field indicates the PID for this transaction.
00 — OUT
01 — IN
10 — SETUP
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 full-speed is
64 bytes as defined in the
Specification Rev.
