In STM32U073, is it not possible to measure VBAT pin voltage when VDDA (3.0V) and VREF+ (2.5V) are separated?
Hi everyone.I'm using the STM32U073.While designing a schematic, I ran out of ports, so I'm curious to see if I can use the "VDD (battery voltage) to VBAT pin" trick to measure the battery voltage. I'm looking at the datasheet and reference manual(RM...
