38.6.2.2 Normal Operation

Once the CAN is initialized and CCCR.INIT bit (CCCR <0>) is reset to ‘0’, the CAN synchronizes itself to the CAN bus and is ready for communication.

After passing the acceptance filtering, received messages including Message ID and DLC are stored into a dedicated Rx Buffer or into Rx FIFO0 or Rx FIFO1.

For messages to be transmitted dedicated Tx Buffers and/or a Tx FIFO or a Tx Queue can be initialized or updated. Automated transmission on reception of remote frames is not implemented.
