This demo is based on the GD32W515P-EVAL-V1.0 board, it shows how to use the ADC analog
watchdog to guard continuously an ADC channel. The ADC is configured in continuous mode,
PA0 is chosen as analog input pin.
Change the VR1 on the GD32W515P-EVAL-V1.0 board, when the channel0 converted value is
over the programmed analog watchdog high threshold (value 0x0A00) or below the analog
watchdog low threshold(value 0x0400), an WDE interrupt will occur, and LED2 will turn on.
When the channel0 converted value is in safe range(among 0x0400 and 0x0A00), the LED2
will be off.
The analog input pin should be configured to AIN mode.
