5.4. External aborts

External memory aborts are defined as those that occur in the memory system rather than those that the MMU detects. External memory aborts are extremely rare. External aborts are caused by errors flagged by the CHI or AXI interfaces or generated because of an uncorrected ECC error in the L1 Data cache or L2 cache arrays.

See Secure Configuration Register, Secure Configuration Register, or the ARM® Architecture Reference Manual ARMv8, for ARMv8-A architecture profile, for more information.
