2.3.4. Fault handling

The MMU-500 supports the terminate and stall fault handling modes. However, the MMU-500 does not support fault model overrides from the global space specified by using the Global Stall Enable (GSE) and Stall Disable (STALLD) bits of the Secure Configuration Register, SMMU_CR0 or SMMU_sCR0.

If the Hit Under Previous Context Fault (HUPCF) bit of the SMMU_CBn_SCTLR Register is not enabled, the MMU-500 applies the fault model across TBUs that share the same context.

See the ARM® System Memory Management Unit Architecture Specification for more information on fault handling.
