Abstract
An initialization or synchronization method in which at least a predetermined number of synchronization messages are sent out over a two-way communication line. The receipt of a synchronization message is awaited before terminating the transmission of synchronization message. After the transmission of synchronization messages has been terminated the receipt of a non-synchronization message will complete the synchronization process. However, certain conditions may cause synchronization to be restarted such as a predetermined number of consecutive error messages, failure to receive any message in a predetermined number of clock signals, receiving more than a predetermined number of synchronization signals, or a reset command.
