6.2.8. Bursts crossing 1KB boundary

The AHB specification requires that bursts must not continue across a 1KB boundary. Linefetches and cache line write backs cannot cross a 1KB boundary because the start address is aligned to either a four or eight-word boundary, and the burst length is fixed.

Uncached data bursts can cross a 1 KB boundary. An example of this is shown in Figure 6.5. The burst is restarted by inserting a nonsequential transfer as the boundary is crossed.
