     14  Baikal-T1 CPU or DMAC MMIO requests are handled by the AMBA 3 AXI Interconnect
     15  which routes them to the AXI-APB bridge. This interface is a single master
     16  multiple slaves bus in turn serializing IO accesses and routing them to the
     17  addressed APB slave devices. In case of any APB protocol collisions, slave
     18  device not responding on timeout an IRQ is raised with an erroneous address
     19  reported to the APB terminator (APB Errors Handler Block).
