CAN
The beCAN3 controller (basic enhanced CAN), interfaces the CAN network and supports
the CAN protocol version 2.0A and B. It has been designed to manage a high number of
incoming messages efficiently with a minimum CPU load.
For safety-critical applications the CAN controller provides all hardware functions to support
the CAN time triggered communication option (TTCAN).
The maximum transmission speed is 1 Mbit.
