Register 30: Memory Management Fault Address (MMADDR), offset 0xD34
Note: This register can only be accessed from privileged mode.
The MMADDR register contains the address of the location that generated a memory management
fault. When an unaligned access faults, the address in the MMADDR register 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. Bits in the Memory
Management Fault Status (MFAULTSTAT) register indicate the cause of the fault and whether
the value in the MMADDR register is valid (see page 113).
