Description
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.
