Access:
• ULBT: Undefined Length Burst Type
0: Unlimited Length Burst
No predicted end of burst is generated, therefore INCR bursts coming from this master can only be broken if the Slave Slot
Cycle Limit is reached. If the Slot Cycle Limit is not reached, the burst is normally completed by the master, at the latest, on
the next AHB 1 KByte address boundary, allowing up to 256-beat word bursts or 128-beat double-word bursts.
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: 4-beat Burst
The undefined length burst is split into 4-beat bursts, allowing re-arbitration at each 4-beat burst end.
3: 8-beat Burst
The undefined length burst is split into 8-beat bursts, allowing re-arbitration at each 8-beat burst end.
4: 16-beat Burst
The undefined length burst is split into 16-beat bursts, allowing re-arbitration at each 16-beat burst end.
5: 32-beat Burst
The undefined length burst is split into 32-beat bursts, allowing re-arbitration at each 32-beat burst end.
6: 64-beat Burst
The undefined length burst is split into 64-beat bursts, allowing re-arbitration at each 64-beat burst end.
7: 128-beat Burst
The undefined length burst is split into 128-beat bursts, allowing re-arbitration at each 128-beat burst end.
Unless duly needed, the ULBT should be left at its default 0 value for power saving.
