no it isn't checksum protected. halting the CPU is also described in the slaa149 application note.

thanks for the advice.  I will check slaa149.

there you also see the state machine and that a few pulses for a "fuse check" are required. to select the register and halt the cpu a number of operations are required, pulses on 3 different pins. the likelihood that this happens by accident is rather small. i've never heard about this happening.

That really sounds as if it's not very likely.

One other thing I'm currently struggling a little bit: is refreshing the special function registers advisable? Is anybody actually doing it?
