The technical documentation mentions that ADC2 supports power and peak detection. It nearly goes as far out of its way as possible to not give any sort of concrete details. What, exactly, is this? What pins does it use? There are very, very few registers that mention PWDET, it is mentioned without really any sort of explanation of how to actually utilize it. Is there any additional documentation on this ADC mode? Is there any example code at all? The ESP-IDF seems to have no examples that cover this. Any insight would be appreciated.

I think this is to detect a WiFi signal and is the reason you can't use adc2 with wifi
