  This example is based on the GD32C231C-EVAL-V1.0, it shows 
how to use the ADC analog watchdog to guard continuously an ADC channel.The ADC is configured 
in continuous mode and PA2/PA4 is chosen as analog input pin.

  Change the VR1 on the board, measure TP pad on the board, when the channel converted value 
is over the programmed analog watchdog high threshold (value 0x0A00) or below the analog watchdog
low threshold(value 0x0400), an WD0E interrupt will occur, and LED1 will be on. When the VR 
converted value is in safe range(among 0x0400 and 0x0A00), the LED1 will be off.

  The analog input pin should be configured to AIN mode.
  We can watch VR converted value by COM.
