  This demo is based on the GD32H759I-EVAL-V1.1 board, it shows how to configure the 
CAN0 peripheral to Pretended Networking mode, and CAN2 peripheral to transmit wakeup frame.

  When TAMPER button is pressed, CAN1 enters Pretended Networking mode. If WAKEUP button is
not pressed within (0xFFFF * 64 / 500K = 8.38) seconds, a wakeup timeout event is occurred,
and LED2 will be toggled, otherwise CAN2 will send a wakeup frame, and a match event will
occur, LED1 is toggled, the received data will be printed inthe hyperterminal.

  User must connect L pin to L pin, and H pin to H pin of JP14 and JP12 on the board for sending and 
receiving frames.

  Jump JP61 and JP53 to CAN, JP50 to LED, JP68 and JP69 to USART.
  GD32H759I-EVAL-V1.1 CAN transceiver needs 5V power supply.
