Question

Can we make ADC functional in Low Power mode for micro-controller STM32L073RZT6.

As per the reference manual "RM0367 Ultra-low-power STM32L0x3 advanced Arm®-based

32-bit MCUs" , page no-298, When the main voltage

regulator is in Low-power run mode (LPR mode, with the device operating in Low-power

run, Low-power sleep or Stop mode), the voltage reference is disabled and the ADC cannot

be used anymore.

If we can configure ADC to function in Low power mode then let me know the register settings for the ADC.

The RM pretty clearly says you can't run the ADC when the regulator is in low-power run mode.

Only option you have is regular sleep mode, which disables the CPU clock but leaves everything else untouched.
