                             Sample Description
================================================================================
功能描述：
此样例演示了MCU进入Stop模式和LPTIM中断唤醒功能，LPTIM中断唤醒后，LED1闪烁一次，再次
进入Stop模式，一直循环。

Function descriptions:
This example demonstrates the MCU entering Stop mode and LPTIM interrupt wake-up
function, After LPTIM interrupt wakes up, LED1 flashes once, then again Enter 
Stop mode and keep looping.

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每隔2s闪烁一次。

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
