Description
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
Controller 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.
