Many microcontrollers include the backup battery as a channel in the ADC mux. That doesn't seem to be the case on the S7G2. Is there some way to monitor the battery level without connecting an ADC pin to the battery?
Good day, Matt! How's it going for you? Have you made any progress on this? I found a thread that might be useful to you. Though this may not be a direct answer to your question, maybe you can get ideas from it. Best of luck!
