  2. ADC clock: PCLK with a 8-bit frequency prescaler Resolution: 10 bits 8 input channels: 0 to 3.6V input range Single Channel / Scan modes Converts one or all 8 channels successively One-Shot or Continuous conversion Standby mode for low power consumption Analog watchdog with interrupt generation When the converted value is above or below a programmed threshold ADC Specifics RTC - Real Time Clock

  3. ADC Block diagram (simplified) RTC - Real Time Clock

  4. ADC register map RTC - Real Time Clock

  5. ADC Control Register RTC - Real Time Clock
