According to the AUTOSAR standard document AUTOSAR_SWS_CANTransportLayer.pdf, organize the configuration parameters information of the CanTp module, and include the corresponding parameter relationship diagram in another article, hoping to show the relationship between the configuration parameters as a whole.
