&par Example Description
This example describes how to make an analog watchdog using APM32A0xx COMP
peripherals devices in window mode:
  - The higher threshold is set VREFINT = 0.92V
  - The lower threshold is set VREFINT = 0.307V
  - The input voltage in configured to be connected to PA1.

When input Voltage is higher than the higher threshold，LED2 and LED3 are turned on,
When input Voltage is under than the lower threshold，LED3 is on,
When input Voltage is under the within threshold，LED2 is on.
