官方规范 4.3.0 The CAN Interface module provides a unique interface to manage different CAN hard- ware device types like CAN Controllers and CAN Transceivers used by the defined ECU hardware layout. Thus multiple underlying internal and external CAN Controller- s/CAN Transceivers can be controlled by the CAN State Managers module based on a physical CAN channel related view.
