                                样例使用说明
                             Sample Description
================================================================================
功能描述：
此样例演示了MCU进入Stop模式和GPIO中断唤醒功能，GPIO中断唤醒后，LED1闪烁一次后进入Stop模式。
给PA8输入上升沿信号，唤醒，同时LED2状态翻转。

Function descriptions:
This example demonstrates the MCU entering Stop mode and GPIO interrupt wake-up function. 
After GPIO interrupt wake-up, LED1 flashes once before entering Stop mode.
Input a rising edge signal to PA8wake up, and simultaneously flip the LED2 state.

测试环境：
测试用板：DPM32M087RBTx_EVB V1.0
MDK版本： 5.28

Test environment:
Test board: DPM32M087RBTx_EVB V1.0
MDK Version: 5.28
================================================================================
使用步骤：
1. 接上P10上的跳线帽，将串口接到USB。
2. 编译下载程序到MCU，并运行。
3. 串口输出日志。
4. 可观察到开发板上的LED1闪烁一次后进入Stop模式。
5. 给PA8输入上升沿信号，唤醒，同时LED2状态翻转。

Example execution steps:
1. Connect the jumper cap on P10 and connect the serial port to USB.
2. Compile and download the program to MCU, and run it.
3. Serial port output logs.
4. It can be observed that LED1 on the development board flashes every 2 seconds.
================================================================================
注意事项：
LED引脚如下：
LED1       -> PC10

Notes:
The LED pins are as follows:
LED1       -> PC10
