CAN protocol ISO 11898 (standard and extended frame transmission/reception)
Maximum 1 Mbps (CAN clock input ≥ 8 MHz)
Storing messages in the CAN RAM
• 32 message buffers/channels
• Each message buffer can be set to be either a transmit message buffer or a receive
• Unique ID can be set to each message buffer.
• Mask setting of four patterns is possible for each channel.
• A receive completion interrupt is generated each time a message is received and stored in
• Two or more receive message buffers can be used as a FIFO receive buffer (multi-buffer
• Receive history list function
• Unique ID can be set to each message buffer.
• Transmit completion interrupt for each message buffer
• Message buffer numbers 0 to 7 specified as transmit message buffers can be used for
• Transmission history list function
Remote frame processing by transmit message buffer
• The time stamp function can be set for a receive message when a 16-bit timer is used in
• The time stamp capture trigger can be selected (SOF or EOF in a CAN message frame
• Readable error counters
• “Valid protocol operation flag” for verification of bus connections
• Receive-only mode
• Single-shot mode
• CAN protocol error type decoding
• Self-test mode
• Can be forcibly released from bus-off by software (timing restrictions are ignored).
• Cannot be automatically released from bus-off (release request by software is required).
• CAN sleep mode (can be woken up by CAN bus)
• CAN stop mode (cannot be woken up by CAN bus)
