I'm looking to use the RTC battery monitor in the PMIC to measure the big battery voltage I have my Pi 5 hooked up to.
What's the safe range of voltages the PMIC can measure, and the RTC can handle? I won't be providing power to it when the Pi is off, but I don't want to damage anything. I can use a voltage divider, but I'd rather not if I don't have to.
