This section contains examples that illustrate segmented LBUS cycles covering various combinations of SOP (Start of Packet), Dat (data in the middle of a packet), EOP (end of packet), and idle (no data on the bus). Valid and invalid cycles are shown.

The segmented LBUS is assumed to be 512 bits wide and each segment is 128 bits wide (16 bytes). The TX direction is illustrated. The RX direction has analogous behavior, but there are no invalid cycles on the receive segmented LBUS.
