The CAN cell first performs a transmission and a reception of a standard data frame by polling at 100 Kbits/s. The received frame is checked and some LEDs light up to indicate whether the communication was successful. Then, an extended data frame is transmitted at 500 Kbits/s. Reception is done in the interrupt handler when the message becomes pending in the FIFO. Finally, the LEDs indicate if both transmission and reception have been successful.
