                             Sample Description
================================================================================
功能描述：
此样例演示了COMP比较器轮询功能，PA1作为比较器正端输入，32/64VREFBUF作为比较器负端输
入，当PA1的电压大于32/64VREFBUF电压时，LED灯亮，小于32/64VREFBUF电压时,LED灯灭。

Function descriptions:
This example demonstrates the interrupt function of the COMP comparator, with PA1
as the positive input and 32/64VREFBUF as the negative input. When the voltage of PA1
is greater than 32/64VREFBUF voltage, the LED lights up, and when it is less than 
32/64VREFBUF voltage, the LED lights up.
