5.7. External aborts

External memory errors are defined as those that occur in the memory system rather than those that are detected by the MMU. External memory errors are expected to be extremely rare. External aborts are caused by errors flagged by the ACE master interface when the request goes external to the Cortex-A7 MPCore processor. You can configure External aborts to trap to Monitor mode by setting the SCR.EA bit to 1.
