m_axi_araddr Output ADDR_WIDTH m_axi_aclk NA Active ARADDR: The read address bus gives the initial address of a read burst transaction. Only the start address of the burst is provided and the control signals that are issued alongside the address detail how the address is calculated for the remaining transfers in the burst.
