This is an CAN FD example that sends and receives 64 byte data messages.
Loopback mode is selected by default so it does not need physical loopback
for demonstration. It sends messages to itself internally and to the CAN bus
so transmitted messages can be captured on the CAN bus also.

Board:                  Atmel 'SAMV71 Xplained Ultra'
Microcontroller:        Atmel 'ATSAMV71Q21'
Clock Settings:         XTAL                =  12 MHz
                        PLLA                = 600 MHz
                        Main Clock = PLLA/2 = 300 MHz
CAN1 Interface:         nominal bit rate 125 kbit/s
                        data    bit rate   1 Mbit/s
User Interface:         input:  none
                        output: SWO
