  This example is based on the GD32VF103V-EVAL board, it shows how to enter mcu sleep
mode and how to wakeup. After power-on, all the LEDs are off. The mcu will enter sleep
mode and the software stops running. When the USART0 receives a byte of data from the
hyperterminal, the mcu will be waked up from a receive interrupt. And all the LEDs will
spark.

  JP5 and JP6 must be fitted to the USART port.
