2.2.3 CAN Interface
The system supports two CAN controllers, each driving its own isolated CAN interface.
Figure 7: CAN interface block diagram
Each CAN interface is connected to one processor, providing redundancy and self-verification capabilities.
Both interfaces are electrically isolated from each other and from the rest of the electronics. They meet the
specifications of the ISO 11898 standard.
