                                样例使用说明
                             Sample Description
================================================================================
功能描述：
此样例演示了WDG的中断和喂狗功能，WDG配置 WDG_MODE_14BIT 模式，每隔500ms产生一次
中断，并在中断里面喂狗和翻转LED2，LED1作为运行指示灯，每隔1000ms翻转一次。

Function descriptions:
This example demonstrates the interrupt and dog feeding functions of WDG. WDG 
is configured with WDG-MODE-14BIT mode, which generates every 500ms Interrupt 
and feed the dog and flip LED2 within the interrupt. LED1 serves as the running 
indicator light and flips once every 1000ms.

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. 编译下载程序到MCU，并运行；
2. 可观察到开发板上的LED1每隔1000ms翻转一次，LED2每隔500ms翻转一次。

Example execution steps:
1. Compile and download the program to MCU, and run it.
2. It can be observed that the four LEDs on the development board light up 
sequentially every 1000ms.

注意事项：
LED引脚如下：
LED1    -> PC10
LED2    -> PC11

Notes:
The LED pins are as follows:
LED1    -> PC10
LED2    -> PC11
