FlexRay Protocol Specification Version 2.1 Revision A 22-December-2005 Disclaimer Page 2 of 245 Disclaimer This specification as released by the FlexRay Consortium is intended for the purpose of information only . The use of material contained in this specification requires membership within the FlexRay Consortium o The Flexray protocol defines a two channel network, Channel A and channel B. A node can be attached to one or both of these channels. If a node is attached to a single channel it does not matter if it is channel A or channel B. The Flexray protocol allows for various bus topologies. These can be FlexRay is composed of static (ST) and dynamic (DYN) segments, which are arranged to form a bus cycle that is repeated periodically. The ST segment is similar to TTP, and employs a generalized time-division multiple-access (GTDMA) scheme. The DYN segment of the FlexRay protocol is similar to Byteflight and uses a flexibl FlexRay Architecture -Protocol Operation Control 11/9/2015 8 FlexRay controller states: 1 - default config 2 - config 3 - ready 4 - wakeup 5 - startup 6 - normal active 7 - normal passive 8 - hal suppliers has recently proposed a hybrid type of protocol, namely the FlexRay communication protocol [11]. FlexRay allows the sharing of the bus among event-driven (ET) and time-driven (TT) messages, thus offering the ad-vantages of both worlds. FlexRay will very likely become the de-facto standard for in-vehicle communications.

The FlexRay communication protocol is specified for a dependable automotive network. The protocol was developed for providing fault-free communication between various electronic components of communication system. Such a system, which consists of finite quantity of electronic components capable of exchanging data, is called distributed system User's Manual -38/165- E-Ray Revision 1.2.5 15.12.2006. manual_programmers_model.fm. 4.4.10 Stop Watch Register 1 (STPW1) The stop watch is activated by a rising or falling edge on pin eray_stpwt, by an interrupt 0,1 event (rising edge on pin eray_int0 or eray_int1) or by the Host by writing bit SSWT to '1' To transfer frames, FlexRay uses a time-trigger protocol, in contrast to CAN's event-trigger protocol. FlexRay's time-trigger method enables accurate data transfers according to a predefined schedule. Additionally, the data is available on dual-redundant communication channels, Ach and Bch. The header segment includes the following bits implementation. The Fr supports multiple FlexRay CCs of this single hardware implementation. The FlexRay Driver's prefix is uniquely assigned per Fr module to allow usage of different FlexRay Drivers, the names of which are separated by namespace. The FrIf can access different FlexRay CC hardware implementation
