Description
Multiplier: This field is a multiplier used by the Host Controller as
the number of successive packets the Host Controller may submit
to the endpoint in the current execution.
Set this field to 01b. You can also set it to 11b and 10b depending
on your application. 00b is undefined.
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 a bulk transfer
is 512 bytes. The maximum packet size for the isochronous
transfer is also variable at any whole number.
Number of Bytes to Transfer: This field indicates the number of
bytes that can be transferred by this data structure. It is used to
indicate the depth of the DATA field (32 kB
-
Valid:
0 — This bit is deactivated when the entire PTD is executed, or
when a fatal error is encountered.
1 — Software updates to one when there is payload to be sent or
received. The current PTD is active.
