For example, for LDMIA R10, {R0-R5} with R10 = 0x1010, the interface might generate one burst of two 64-bit reads, and one burst of a single 64-bit read, as shown in Table 9.20. Table 9.20.

WebAHB and AXI both has a burst kind called 'WRAP' What does it mean, and why it is there, and how it is used? AHB WRAP burst 'wraps' around Burst Boundary. Let us see an example.

If you check most Xilinx IP, the width of AXI_AWADDR and AXI_ARADDR are quite small, for example 8-bits. So when you use the address 0x00_A000_0000 the IP will only receive the last part, i.e. 0x00.
