The real-time clock\/calendar circuit provides seconds, hours, days, weeks, months, years of information, a number of days in the month and leap year can automatically adjust. The clock operation instructions through the AM\/PM decided to use a 24 or 12-hour format.\u003cbr\u003e\u003cbr\u003eBetween DS1302 and single-chip microcomputer can simply use synchronous serial communication method, only three lines:\u003cbr\u003e(1) RST\u003cbr\u003e(2) I\/O reset the data line\u003cbr\u003e(3) SCLK serial clock.\u003cbr\u003e\u003cbr\u003eClock \/RAM read\/write data to a byte character set or as many as 31-byte communication.
