                             Sample Description
================================================================================
功能描述：
此样例演示了COMP比较器中断功能，PD0作为比较器正端输入，1/2VCC作为比较器负端输
入，当PD0的电压大于1/2VCC电压时，LED灯亮，小于1/2VCC电压时,LED灯灭。

Function descriptions:
This example demonstrates the interrupt function of the COMP comparator, with
PD0 as the positive input and 1/2VCC as the negative input. When the voltage
of PD0 is greater than 1/2VCC voltage, the LED lights up, and when it is less
than 1/2VCC voltage, the LED lights out.
