Dear all,

Now I'm working on 10s-BMS development using BQ78350-R1 and BQ76930.

I'd like to set SUV and SOV of permanent fail function, but I can't find it on BQSTUDIO.

It shows RSVD, please find attached picture.

Is it a bug in BQSTUDIO ?

These bits are set to RSVD, because the SOV and SUV protection features cannot be disabled from turning the FETs off. You can use the PF SAFE A register to enable them to blow the fuse.
