Description
No predicted end of burst is generated and therefore INCR bursts coming from this
master cannot be broken.
The undefined length burst is treated as a succession of single accesses, allowing re-
arbitration at each beat of the INCR burst.
The undefined length burst is split into a four-beat burst, allowing re-arbitration at each
four-beat burst end.
The undefined length burst is split into an eight-beat burst, allowing re-arbitration at
each eight-beat burst end.
The undefined length burst is split into a sixteen-beat burst, allowing re-arbitration at
each sixteen-beat burst end.
