Control Area Network (CAN) is a serial communication protocol with high level of security. Each
node is master on the bus but only one at a time is able to send a message.
CANIF is a 32-bit interface for CAN channels. Each channel provides the following services:
These services, with the exception of message filtering and message handling, are described in
the CAN protocol, please refer to Bosch - CAN Specification for more details.

• Message and status handling
• Fault confinement
• Error detection and signalling
• Message validation and acknowledgement
• Bus arbitration
• Message framing
• Transfer rate and timing
