I don't get 0x3X or 0x4X values if SLEEPY mode is on.
The voltage is higher than I expected (with 20K resistor), get 4.4V instead of 2.5V, as if there's a 4.7K pull-up enabled (there isn't near as I can tell. Measured with Fluke right across the terminals of the RVC jack.
Turning off SLEEPY mode changes power consumption from 4.4mA to 7.5mA, which decreases battery life from about 130 hrs to about 76 hrs. But, then the ADC works as expected. So, I've turned it off for now.
It would be good to fix this to get power consumption back down.
