Hi,
As mentioned in the document I shared earlier, To mark a start of packet, both the user and priority data have a 2-byte sequence appended to them. The user data is preceded by a start-of-data packet
sequence {SDP} while the priority data uses the start-of-priority packet sequence {SPP}. The second byte located in the start-of-packet sequences is for segment identification and channel number.
I think for 32 bit width ports, the first two byte will be used for SDP1 and SDP2.
The rest will be data payload, or it will be ignored.
We no longer support serial lite II IP..... But I will ask around to see if we have the exact answer.- Please let me know if you have any other query.
Thank you
