Title: Bus station and system and method of maintaining synchronizing of a bus station

Abstract: A bus station circuit (14) operates in an electronic system with a bus (10). The bus station determines an initial synchronization time point by detecting a synchronization signal pattern on the bus and switching to a synchronization enabled state upon detection of the synchronization signal pattern. Starting points of successive messages are determined head to tail from the end points of immediately preceding messages, when operating in the synchronization enabled state. The content of the messages is tested for validity. The bus station switches to a synchronization disabled state in response to detection of a message with invalid content. While in the synchronization disabled state, use of messages that are received is disabled in the bus station circuit. In the synchronization disabled state the bus station waits for a synchronization event to switch back to the synchronization enabled state.
