Burst access:
The number of clocks required
This case is illustrated in
10.2.6.3
With normal setup time and a 4-beat burst, a 4-2-2-2 burst cycle is required which is reduced to a 4-1-1-1
burst cycle with a short setup time. Short setup time creates a saving of three clock cycles with a 4-beat
burst and can result in even better performance with an 8-beat burst, saving seven clock cycles.
