  This demo is based on the GD32C113V-EVAL-V1.0 board, it shows how to configure the 
CAN0 and CAN1 peripherals to send and receive CAN frames in FD mode. Pressing 
Wakeup button or Tamper button:

  When Tamper button is pressed, CAN0 sends a message to CAN1 and print it.
when CAN1 receives correctly this message,the receive data will be printed
and LED3 toggles one time. 

  When Wakeup button is pressed, CAN1 sends a message to CAN0 and print it.
when CAN0 receives correctly this message,the receive data will be printed
and LED2 toggles one time.

  User can select one from the preconfigured CAN baud rates from the private 
defines in main.c.  

  Connect JP14 CAN_L to JP15 CAN_L
  Connect JP14 CAN_H to JP15 CAN_H
  P2 and P3 must be fitted to the CAN0 port.
  P4 must be fitted to the CAN1 port.
  JP5 and JP6 must be fitted to the USART0 port.
