Bits 31:0 – FAIL_ADDRESS[31:0] Failure Access Address
If a region permission check fails or a region overlap occurs, this field returns the bus address of the first failed access. The associated interrupt status must be cleared before this field can return the address of accesses of subsequent permission checks or region overlap failures.
This occurs even if TZC_SYS_ACTION does not enable the interrupt.
If the status flag for the filter unit in TZC_SYS_INT_STATUS is already set, new region permission check failures in the same filter unit do not update the associated fail status group of registers.
