Description
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 the 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. Zero for the internal or
embedded hub.
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. The following applies to start split and complete split 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 Universal Serial Bus Specification Rev. 2.0 .
