                                样例使用说明
                             Sample Description
================================================================================
功能描述：
此样例演示了GPIO外部中断功能，PA0引脚上的每一个下降沿都会产生中断，中断函数中
LED灯会翻转一次。

Function descriptions:
This example demonstrates the GPIO external interrupt function, where each
falling edge on the PA0 pin generates an interrupt, and the LED light in the
interrupt function flips once.
================================================================================
测试环境：
测试用板：PY32F403_STK
MDK版本： 5.28
IAR版本： 9.20
GCC 版本：GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
Test board: PY32F403_STK
MDK Version: 5.28
