Hi,

basically I realize that an ATmega4809 and relatives cannot measure their own Ub. What, for example, an ATmega328P can do. Measure its own UB backwards via bandgap. Measuring Vcc I'm asking you anyway. Is there perhaps a hidden possibility for megaAVR0 to configure an internal bandgap via ADC Portmux?
