7.3.6. AXI3 Compatibility mode

The Cortex-A7 MPCore processor implements an AXI3 compatibility mode that enables you to use the processor in a standalone environment where the AMBA 4 ACE interface is not required and the processor does not propagate barriers outside of the cluster. To enable this mode you must set the SYSBARDISABLE input pin to 1 on the boundary of the processor. When SYSBARDISABLE is set to 1, you must ensure the BROADCASTINNER, BROADCASTOUTER, and BROADCASTCACHEMAINT input pins are set to 0.
