ULBT
⢠ULBT: Undefined Length Burst Type
0: Infinite Length Burst
No predicted end of burst is generated and therefore INCR bursts coming from this master cannot be broken.
1: Single Access
The undefined length burst is treated as a succession of single accesses, allowing re-arbitration at each beat of the INCR burst.
2: Four Beat Burst
The undefined length burst is split into a four-beat burst, allowing re-arbitration at each four-beat burst end.
3: Eight Beat Burst
The undefined length burst is split into an eight-beat burst, allowing re-arbitration at each eight-beat burst end.
4: Sixteen Beat Burst
The undefined length burst is split into a sixteen-beat burst, allowing re-arbitration at each sixteen-beat burst end.
