Using STM8L051 ADC PD0, 3.7V~4.2V Li-Po battery, 1M+1M resistor to divde the battery voltage, 100nF capacitor to GND.If set PD0 floating input and halt, total current 40uA, if set PD0 push-pull output LOW, 10uA. But the drawback of output LOW is that...

Hi,STM8L152 with buttons and LCD, using CR2032 battery. Most of time MCU is in Active-halt mode and keep LCD display. Now I want PVD low voltage interrupt to inform user to change battery in LCD.​So my question is, can PVD interrupt work in active-ha...
