• Manufacturer Part Number: mfr4300
• Description: Flexray Communication Controllers
• Manufacturer: Freescale Semiconductor, Inc

This register provides the number of the last transmission slot in the dynamic segment for channel A. This
register is updated after the end of the dynamic segment and before the start of the next communication
cycle.
3.3.2.62
This register provides the number of the last transmission slot in the dynamic segment for channel B. This
register is updated after the end of the dynamic segment and before the start of the next communication
cycle.
3.3.2.63
The following configuration registers provide the necessary configuration information to the protocol
engine. The individual values in the registers are described in
FlexRay related configuration parameters and the allowed parameter ranges, see FlexRay
Communications System Protocol Specification, Version 2.1.

Last Dynamic Transmission Slot Channel A — protocol related variable:
Number of the last transmission slot in the dynamic segment for channel A. If no frame was transmitted during
the dynamic segment on channel A, the value of this field is set to 0.
Last Dynamic Transmission Slot Channel B — protocol related variable:
Number of the last transmission slot in the dynamic segment for channel B. If no frame was transmitted during
the dynamic segment on channel B the value of this field is set to 0.
