Time Synchronization in Serial Communications
A real-time clock (151) for electronic equipment is synchronized by supplying a time signal (4-1) to a serial communications circuit (11) with the data transmission rate adapted so that one character of the time signal can be read into the serial communications circuit as one character. The serial c...

| Zusammenfassung: | A real-time clock (151) for electronic equipment is synchronized by supplying a time signal (4-1) to a serial communications circuit (11) with the data transmission rate adapted so that one character of the time signal can be read into the serial communications circuit as one character. The serial communications circuit (11) initiates (4-2) an interrupt handler (131) that in turn initiates (4-7) a sync task (132). The time signal (4-1) is inverted if necessary before being supplied to the serial communications circuit (11). |
