- MARKing a location can only occur during a Queue switch cycle
- There is only one MARKed location within a Queue
- Only 1 packet can be MARKed at a time within a Queue.
- In packet mode, for a full packet re-write the MARK must occur at the SOP location of the packet.
- In packet mode data can be re-written from the MARK
- In packet mode the MARK moves from packet to packet within a queue when the next packet is written.
- The sequence to move the MARK to the next packet is, first an EOP must occur, then a valid write occurs.
- MARKing can only occur during a Queue switch cycle
- Only 1 packet can be MARKed at a time within a Queue.
- In packet mode, MARK is moved to a location of the packet.
-
In packet mode the MARK can be moved from SOP (start of packet) to SOP (start of packet) within the queue by a valid read.
