Lost register in bq78350

Other Parts Discussed in Thread: BQ78350, BQSTUDIO

I can't find the register "Min SAFE Activation Voltage" (end of section 4.3 in bq78350 TRM) in bqStudio nor can I find it in the Data Flash Summary Table (18.1).

Does it really exist?

    Min SAFE Activation voltage does exist in the device but is hidden.  Its value is 3500 mV, it is pack based and voltage scaling is used.  Since shutdown voltage on the AFEs is 3.6V per cell group, the fuse should always activate.

    Thanks for bringing this to our attention.
