Rev. 04 — 4 February 2008
Active: This bit is the same as the Valid bit.
Halt: Only one bit for the entire millisecond. When this bit is set, the
Valid bit is reset. The device decides to stall an endpoint.
Babble: Not applicable here.
Set to 0 for isochronous.
Number of Bytes Transferred: This field indicates the number of
bytes sent or received for this transaction. If Mult[1:0] is greater than
one, it is possible to store intermediate results in this field.
NrBytesTransferred[14:0] is 32 kB
Set to 0 for isochronous.
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
Bits 2 to 0 — Don’t care
Bits 7 to 3 — Frame number that this PTD will be sent for ISO OUT or
IN
-
This bit indicates whether a split transaction has to be executed.
0 — High-speed transaction
1 — Split transaction
Endpoint type:
01 — Isochronous
Token: This field indicates the 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.
This field is a multiplier counter used by the host controller as the
number of successive packets the host controller may submit to the
endpoint in the current execution.
For details, refer to Appendix D of
Interface Specification for Universal Serial Bus Rev.
Maximum Packet Length: This field indicates the maximum number
of bytes that can be sent to or received from the endpoint in a single
data packet. The maximum packet size for an isochronous transfer is
1024 bytes. The maximum packet size for the isochronous transfer is
also variable at any whole number.
