The translation table walk for an ATS instruction can result in various faults. In general these are just reported back via the PAR_EL1 fault status fields, but in some cases the architecture requires that the fault is turned into an exception: * synchronous stage 2 faults of any kind during AT S1E0* and AT S1E1* instructions executed from NS EL1 fault to EL2 or EL3 * synchronous external aborts are taken as Data Abort exceptions (This is documented in the v8A Arm ARM DDI0487A.e D5.2.11 and G5.13.4.)
