Description
-
Transaction Translator Maximum Packet Size Length: This field
indicates the maximum number of bytes that can be sent per start
split, depending on the number of total bytes needed. If the total
bytes to be sent for the entire millisecond is greater than 188 bytes,
this field should be set to 188 bytes for an OUT token and
192 bytes for an IN token. Otherwise, this field should be equal to
the total bytes sent.
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. This field is restricted to
1023 bytes because in siTD the maximum allowable payload for a
full-speed device is 1023 bytes. This field indirectly becomes the
maximum packet size of the downstream device.
-
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.
