  This demo is based on the GD32E517Z-EVAL-V1.0 board, it shows how to use the ADC 
analog watchdog 1 to guard continuously an ADC channel. The ADC is configured in 
continuous mode and PC0 is chosen as analog input pin.

  Change the VR1 on the GD32E517Z-EVAL-V1.0 board, measure TP pad on the board, 
when the channel10 converted value is over the programmed analog watchdog 1 high 
threshold (value 0xA0) or below the analog watchdog 1 low threshold (value 0x40), 
an WDE1 interrupt will occur, and LED2 will be on. When the VR converted value is 
in safe range (among 0x40 and 0xA0), the LED2 will be off.

  The analog input pin should be configured to AIN mode.
