Brief Functional Description

The low cost basic FlexRay? transceiver is part of the electrical, physical layer in a FlexRay? communication network. The E910.54 provides an interface between the twisted pair physical bus medium and a communication controller (CC). An SPI interface connects the bus driver (BD) to a host controller (HOST) to provide status information concerning failure detection on the bus lines (e.g. short-circuits, ground loss) and overtemperature condition. An interrupt signal is generated whenever the failure status changes.
