Brief Functional Description

The star coupler is part of the electrical, physical layer in a FlexRay? communication network. The E910.56 provides interfaces to connect up to four branches of twisted pair physical bus lines to other bus drivers or star couplers. It also interfaces with a communication controller (CC) and a μC. Via SPI the bus driver (BD) provides status information concerning failure detection on the bus lines (e.g. short circuit, ground loss) and overtemperature condition to a host controller (HOST). An interrupt signal is generated whenever the failure status changes.
