I. Flexray Frame
   Most embedded networks have a small number of high-speed messages and a large number of lower-speed, less-critical networks.  To accommodate a wide variety of data without slowing down the FlexRay cycle with an excessive number of static slots, the dynamic segment allows occasionally transmitted data.  The segment is a fixed length, so there is a limit of the fixed amount of data that can be placed in the dynamic segment per cycle. To prioritize the data, minislots are pre-assigned to each frame of data that is eligible for transmission in the dynamic segment.  A minislot is typically a macrotick (a microsecond) long. Higher priority data receives a minislot closer to the beginning of the dynamic frame.  [14][18]
