22.5.2.67 Protocol Configuration Registers
The following configuration registers provide the necessary configuration information to the protocol
engine. The individual values in the registers are described in Table 22-77. For more details about the
FlexRay related configuration parameters and the allowed parameter ranges, see FlexRay
Communications System Protocol Specification, Version 2.1 Rev A.
