Each slot of a static or dynamic segment contains a FlexRay Frame. The frame is divided into three segments: Header, Payload, and Trailer. The Header is 5 bytes (40 bits) long and includes the following fields:
1. Status Bits - 5 bits
2. Frame ID - 11 bits
3. Payload Length - 7 bits
4. Header CRC - 11 bits
5. Cycle Count - 6 bits
