Fehlererkennung und Fehlerbeseitigung bei einem seriellen Datenbussystem

The invention concerns a process which involves testing the SDA line (3) after a reset and is intended for use with a serial data bus with master (2) and slave (4) systems, preferably an I C bus with a microcontroller and (for example) E PROM. If the SDA line is at low potential, an error is recogni...

Zusammenfassung:The invention concerns a process which involves testing the SDA line (3) after a reset and is intended for use with a serial data bus with master (2) and slave (4) systems, preferably an I C bus with a microcontroller and (for example) E PROM. If the SDA line is at low potential, an error is recognised and eliminated by running a sub-program.
