Real-time clock \/ calendar circuit provides seconds, minutes, hours, days, weeks, months, years of information, the number of days per month and leap year automatically adjust the number of days.\u003c\/p\u003e\n\u003cp\u003eClock operation by AM \/ PM indicator decided to use 24 or 12 hour format. DS1302 between the microcontroller can simply adopt the way synchronous serial communication port only used three lines: (1) RST Reset (2) I \/ O data lines (3) SCLK Serial Clock. Clock \/ RAM read \/ write data in a byte or up to 31 bytes of character set type communication.
