Access
Value Description
DW3
63
A
HW — writes -
Active: Write the same value as that in V.
SW — writes
62
H
HW — writes -
Halt: Transaction is halted.
61 to 58 reserved

57
DT
HW — writes -
SW — writes
Data toggle: Set the Data Toggle bit to start the PTD. The software
writes the current transaction toggle value. The hardware writes the
next transaction toggle value.
56 to 55 Cerr[1:0]
HW — writes -
SW — writes
Error counter: This field corresponds to the Cerr[1:0] field in TD. The
default value of this field is zero for isochronous transactions.
54 to 47 reserved

46 to 32 NrBytes
Transferred
[14:0]
HW — writes -
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.
DW2
31 to 24 reserved

23 to 8 DataStart
SW — writes -
Address[15:0]
Data start address: This is the start address for data that will be sent
on or received from the USB bus. This is the internal memory address
and not the direct CPU address.
RAM address = (CPU address  400h) / 8
7 to 0 Frame[7:0] SW — writes -
Frame: Bits 7 to 3 represent the polling rate in milliseconds.
The INT polling rate is defined as 2^{(b  1)} SOF, where b is 1 to 9.
When b is 1, 2, 3, or 4, use SA to define polling because the rate is
equal to or less than 1 ms. Bits 7 to 3 are set to 0. Polling checks SA
bits for SOF rates. See Table 80.
DW1
63 to 47 reserved
-

-
46
S
SW — writes -
Split: This bit indicates if a split transaction has to be executed:
0 — High-speed transaction
1 — Split transaction
45 to 44 EPType[1:0] SW — writes -
Endpoint type:
11 — Interrupt
43 to 42 Token[1:0]
SW — writes -
Token: This field indicates the token PID for this transaction:
00 — OUT
01 — IN
41 to 35 DeviceAddress SW — writes -
[6:0]
Device address: This is the USB address of the function containing
the endpoint that is referred to by the buffer.
34 to 32 EndPt[3:1]
SW — writes -
Endpoint: This is the USB address of the endpoint within the
function.
DW0
31
EndPt[0]
SW — writes -
Endpoint: This is the USB address of the endpoint within the
function.
