General: What are the different bursts used for?

Applies to: AHB


Typically a master would use wrapping bursts for cache line fills where the master wants to access the data it requires first and then it completes the burst to fetch the remaining data it requires for the cache line fill. Incrementing bursts are used by masters, such as DMA controllers, that are filling a buffer in memory which may not be aligned to a particular address boundary.
