13.20.13 Memory Management Fault Address Register
• ADDRESS
When the MMARVALID bit of the MMFSR is set to 1, this field holds the address of the location that generated the memory
management fault
When an unaligned access faults, the address is the actual address that faulted. Because a single read or write instruction
can be split into multiple aligned accesses, the fault address can be any address in the range of the requested access size.
Flags in the MMFSR indicate the cause of the fault, and whether the value in the MMFAR is valid. See
ment Fault Status Register” on page
