Missing SOP
If incoming data contains one or more EOPs without corresponding SOPs (refer to
Figure 4–9 ), the block deasserts the enable after the last EOP (refer to Figure 4–10 ).
This deassertion indicates that the current data between the SOP to EOP transition is a
valid packet, and that everything following the EOP is discarded until the next SOP is
received. None of the packets are marked as errored, so it is up to the user logic to
determine which cells or packets have been dropped.
