• 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 access allowing rearbitration at each beat of the INCR
burst.
2: Four Beat Burst
The undefined length burst is split into 4 beats burst allowing rearbitration at each 4 beats burst end.
3: Eight Beat Burst
The undefined length burst is split into 8 beats burst allowing rearbitration at each 8 beats burst end.
4: Sixteen Beat Burst
The undefined length burst is split into 16 beats burst allowing rearbitration at each 16 beats burst end.
