• PRECISERR
Precise data bus error:
0 = no precise data bus error
1 = a data bus error has occurred, and the PC value stacked for the exception return points to the instruction that caused
the fault.
When the processor sets this bit is 1, it writes the faulting address to the BFAR.
• IBUSERR
Instruction bus error:
0 = no instruction bus error
1 = instruction bus error.
The processor detects the instruction bus error on prefetching an instruction, but it sets the IBUSERR flag to 1 only if it
attempts to issue the faulting instruction.
When the processor sets this bit is 1, it does not write a fault address to the BFAR.
