34.3.4.4 Lockup
The processor enters a lockup state if a hard fault occurs when executing the NMI or hard
fault handlers. When the processor is in lockup state it does not execute any instructions.
The processor remains in lockup state until either:
• it is reset
• an NMI occurs.
Remark: If lockup state occurs from the NMI handler a subsequent NMI does not cause
the processor to leave lockup state.
