working of Real time clock
I saw the data sheet but there is no much information. How does RTC work.
RTC start with current and time and date then we set alarm time and date then how does alarm happen. I saw there is mask and alarm handler mask is used to match current time date with alarm time and date and alarm handler is used to call the alarm function
So please tell how does RTC work from beginning??
