                             Sample Description
================================================================================
功能描述：
此样例演示了MCU进入DeepSleep模式和串口接收中断唤醒功能，串口接收中断唤醒后，LED1闪烁一次，再次
进入DeepSleep模式，一直循环。

Function descriptions:
This example demonstrates the MCU entering DeepSleep mode and the serial port 
receiving interrupt wake-up function. After the serial port receives interrupt 
wake-up, LED1 flashes once, then again Enter DeepSleep 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. 上位机发送1字节数据，MCU唤醒一次，LED1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. The upper computer sends 1 byte of data, MCU wakes up once, LED1 flashes once.

注意事项：
LED引脚如下：
LED1       -> PC10

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