10.21.14 Bus Fault Address Register
The BFAR contains the address of the location that generated a bus fault. See the register sum-
mary in Table 10-30 on page 164 for its attributes. The bit assignments are:
• ADDRESS
When the BFARVALID bit of the BFSR is set to 1, this field holds the address of the location that generated the bus fault
When an unaligned access faults the address in the BFAR is the one requested by the instruction, even if it is not the
address of the fault.
Flags in the BFSR indicate the cause of the fault, and whether the value in the BFAR is valid. See “Bus Fault Status Regis-
ter” on page 183.
