6.5.2. Precise and imprecise aborts

Chapter 3 System Control Coprocessor describes precise and imprecise 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.
