34.4.3.11.1 Memory Management Fault Status Register
34.4.3.11 Configurable Fault Status Register
The CFSR indicates the cause of a memory management fault, bus fault, or usage fault.
See the register summary in
The following subsections describe the subregisters that make up the CFSR:
The CFSR is byte accessible. You can access the CFSR or its subregisters as follows:
The flags in the MMFSR indicate the cause of memory access faults. The bit assignments
are shown in

Function
Memory Management Fault Address Register (MMAR) valid flag:
0 = value in MMAR is not a valid fault address
1 = MMAR holds a valid fault address.
If a memory management fault occurs and is escalated to a hard
fault because of priority, the hard fault handler must set this bit to 0.
This prevents problems on return to a stacked active memory
management fault handler whose MMAR value has been
overwritten.
Reserved.
Memory manager fault on stacking for exception entry:
0 = no stacking fault
1 = stacking for an exception entry has caused one or more access
violations.
When this bit is 1, the SP is still adjusted but the values in the
context area on the stack might be incorrect. The processor has not
written a fault address to the MMAR.
