2.4.2 Fault escalation and hard faults
All faults exceptions except for hard fault have configurable exception priority, see Section 4.3.9 (p.
102) . Software can disable execution of the handlers for these faults, see Section 4.3.10 (p. 103) .
Usually, the exception priority, together with the values of the exception mask registers, determines
whether the processor enters the fault handler, and whether a fault handler can preempt another fault
handler. as described in Section 2.3 (p. 22) .
In some situations, a fault with configurable priority is treated as a hard fault. This is called priority
escalation, and the fault is described as escalated to hard fault. Escalation to hard fault occurs when:
A fault handler causes the same kind of fault as the one it is servicing. This escalation to hard fault
occurs because a fault handler cannot preempt itself because it must have the same priority as the
current priority level.
A fault handler causes a fault with the same or lower priority as the fault it is servicing. This is because
the handler for the new fault cannot preempt the currently executing fault handler.
An exception handler causes a fault for which the priority is the same as or lower than the currently
executing exception.
A fault occurs and the handler for that fault is not enabled.
If a bus fault occurs during a stack push when entering a bus fault handler, the bus fault does not escalate
to a hard fault. This means that if a corrupted stack causes a fault, the fault handler executes even though
the stack push for the handler failed. The fault handler operates but the stack contents are corrupted.
Note
Only Reset and NMI can preempt the fixed priority hard fault. A hard fault can preempt any
exception other than Reset, NMI, or another hard fault.
2.4.3 Fault status registers and fault address registers
The fault status registers indicate the cause of a fault. For bus faults and memory management faults,
the fault address register indicates the address accessed by the operation that caused the fault, as
shown in Table 2.18 (p. 30) .
