I only can find the POF bit too so seems no other flag aviable.

I'm working on a system with IAP for re-configure it the idea was:
If the "downloaded" program don't works push the reset and the system let you try again.
When is tested the aplication you can let the system stand alone, when the power fails and returs the app will be runing again whitout human action.

I will report how works POF if i can make it working
