    Yes, that was my original question and the goal.

    Ad 1. I've recently received some info on this subject from one of the FAE's, that's very much under NDA, regarding the use of the internal JTAG in the discussed topic. I hope I won't violate the NDA by saying this: It's not impossible.

    Ad 2. That's a very good point. Removing the VCCBAT indeed causes the POR and needs to be extended by external logic, i.e. a monoflip. Having an external security controller, it's easy to implement.

    That solves my question. Thank You a lot!
