Quote: ARM, ARMv6
Under the ARMv6-M exception priority scheme, a processor handles a precise fault in one of the following ways:

[LIST]
[*] -by taking a HardFault exception
[*] -by using the Lockup mechanism in the case of a fault arising while executing a HardFault or NMI, (...)
[/LIST]

In ARMv6-M, faults are considered fatal. The only fault status information provided on entry to the HardFault handler is the EXC_RETURN value, that indicates whether the fault originated from Thread or Handler mode.
