Howdy, I can't find this info in the datasheet. I measured (on a 3.3Vdd) 1.30V and= 1.64V, but I'd like to know if there are any official infos about these values. Also, by making the (digital) input deliberately "float", I measured no ano= maly in the current drawn by the MPU. Perhaps the schmitt trigger prevents this to = happen?
