This anomaly applies to Revision 2, build code CAAA-Bxx.
It was inherited from the previous SoC revision Revision 1.
Symptoms
The CPU hangs.
Conditions
NVMC write or erase operation when POFWARN is asserted, and with low probability when POFWARN is asserted while an NVMC write or erase operation is ongoing.
Consequences
Code execution is halted.
Workaround
Disable POFWARN by writing POFCON before a write or erase operation. Do not attempt to write or erase if EVENTS_POFWARN is already asserted.
