4.2.5.5.3 Cache Fill Operation Utilizing Bursts

The internal cache fill operations using AHB wrapping can utilize bursts to optimize the cache fill operations. The AHB-NVM controller always returns 8 words in a burst. The first word returns after 9 clock cycles, and second word in the following cycle as shown in the preceding figure. But the third word occurs 7 clock cycles later, and the fourth word occurs a cycle later with a repeating pattern for the remaining words as shown in following figure. This burst transfer is 8 clock cycles quicker than a non-burst sequence of read commands.
