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 is not enabled, the MMU-500 applies the fault model across TBUs that share the same context.
