10.21.13 Memory Management Fault Address Register
The MMFAR contains the address of the location that generated a memory management fault.
See the register summary in Table 10-30 on page 164 for its attributes. The bit assignments are:
• 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 “Memory Manage-
ment Fault Status Register” on page 182.
