As shown in the screenshot below. RUN_PD bit is mentioned here and nowhere else in the entire Reference manual.  

Hi, I am just trying to run adc in discontonous mode to measure some voltate from two resistor divider connected on channel 6 (PA1) and channel 7 (PA2) and also Vref from internal channel 12 as per datasheet. see below screenshot from DS14581- Rev2 ...

LDORDY bit does not exist in any registers mentioned in RM0503 rev 2 . I am using ADC1 in STM32U031R6T6 and the code migrated from STM32L010R8T6 is not working .
