13.6.6.2 Synchronous and Asynchronous Aborts

The section System Control in the Cortex-A5 Technical Reference Manual describes synchronous and asynchronous aborts, their priorities, and the IFSR and DFSR. To determine a fault type, read the DFSR for a data abort or the IFSR for an instruction abort.

The processor supports an Auxiliary Fault Status Register for software compatibility reasons only. The processor does not modify this register because of any generated abort.
