ULBT Undefined Length Burst Type Description
000 Inifinite Length Burst No predicted end of burst is generated and therefore INCR bursts coming from this

arbitration at each beat of the INCR burst.
010 4 Beat Burst The undefined length burst is split into a four-beat burst, allowing re-arbitration at each
four-beat burst end.
011 8 Beat Burst The undefined length burst is split into an eight-beat burst, allowing re-arbitration at
each eight-beat burst end.
100 16 Beat Burst The undefined length burst is split into a sixteen-beat burst, allowing re-arbitration at
each sixteen-beat burst end.
