|Home > Functional Description, AXI5 to AHB5 bridge > 1KB boundary crossing|
The AHB protocol requires that bursts do not cross 1KB boundaries. Since AXI5 transactions can cross a 1KB boundary, the AXI5 to AHB5 bridge must ensure that a transfer does not cross a 1KB boundary.
If an AXI transaction crosses a 1KB boundary, the bridge converts the transaction to undefined length INCR bursts, and htrans is set to NONSEQ on the first address after crossing the 1KB boundary.
