11.7.6
Access: Read/Write
Reading the CP 15 Register 5, or Fault Status Register (FSR), returns the source of the last data fault, indicating the
domain and type of access being attempted when the data abort occurred.
In addition, the virtual address which caused the data abort is written into the Fault Address Register (CP15 Register 6).
Writing the CP 15 Register 5, or Fault Status Register (FSR), sets the FSR to the value of the data written. This is useful for
a debugger to restore the value of the FSR.
• Status[3:0]: Fault Type
Indicates the fault type. The status field is encoded by the MMU when a data abort occurs. The interpretation of the Status
field is dependant on the domain field and the MVA associated with the data abort (stored in the FAR).
• Domain[7:4]: Domain
Indicates the domain (D15 - D0) being accessed when the fault occurred.
The non-defined bits should be zero when written and are unpredictable when read.
