hi,
My RTC is driverd by external 32.768K  clock source. It works well,if the MCU does not enter standby mode. Let the MCU enter standby mode and wake up every 60 seconds by alarm, RTC will slow about 6 seconds during 10 minutes  .However Let the MCU enter standby mode and wake up every 300 seconds(or more) by alarm, RTC works well. Will the wake freqency have influence on RTC?
