The features are described as follows:
 Configurable conversion accuracy (6/8/10/12)
 Interrupt generation at the end of conversion, the end of injected conversion, analog
watchdog or overrun events.
 Support single and continuous conversion modes
 Scan mode for automatic conversion of channel 0 to channel “n”
 Configurable data alignment
 Programmable sampling time of each channel
 External trigger option to configure polarity for both regular and injected conversion
 Support discontinuous sampling mode
 Configurable conversion clock divider
 DMA request generation during regular channel conversion
4.15 Real Time Clock(RTC)
Real Time Clock (RTC) can provide users with accurate time and date information. These keywords are
stored in the RTC control register in BCD format to provide users with the alarm function. There are two
RTC CLK sources for users to choose from, which are an external 32.768K Hz crystal oscillator and an
internal 32.768K Hz RC oscillator. When the MCU is in low power consumption mode, the RTC can still
continue to provide accurate time information.
The features are described as follows:

Support calendar display: year, month, day
 Support time display: week, hour, minute, second

The calendar and time are stored in BCD format
 Support leap year detection capability

Support users to set the RTC counter correction function
 Support users to set the alarm interrupt function

Support rollover interrupt of year, month, day, week, hour, minute, and second
 Support MCU to keep counting in sleep mode

Support users to configure the sleep counter
 Support a sleep counting up to 16777216 seconds (194 days).

Support a sleep counting as short as 1/16 second.
 Support to detect whether the calendar and time have been cleared.
