5.2.1.4 Synchronous/Asynchronous External

This happens when the access has been transferred from the CPU to the AXI/AHB Bus and encountered an error. This is the most common fault type that happens with Data Abort. If the Abort is Synchronous, you can check the actual memory address that when accessed resulted in Data Abort using Data Fault Address Register (DFAR), which holds the address of the fault when a synchronous abort occurred.
