                                样例使用说明
                             Sample Description
================================================================================
功能描述：
该样例演示了EPWM的正常输出和中断功能，PA7,PA8正常输出EPWM波形，EPWM溢出中断翻转LED2，
LED1每隔1s翻转一次。

Function descriptions:
This example demonstrates the normal output and interrupt functions of EPWM, PA7 
and PA8 output EPWM waveforms normally, EPWM overflow interrupt flips LED2, LED1 
flips every 1 second.
================================================================================
测试环境：
测试用板：DPM32M08X_EVB V1.0
MDK版本： 5.38


Test environment:
Test board: DPM32M08X_EVB V1.0
MDK Version: 5.38

================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行。
2. 可在PA7,PA8引脚上观察到EPWM波形。
3. 可观察到开发板上的LED1每隔1s翻转一次。
3. EPWM溢出中断翻转LED2。

Example execution steps:
1. Compile and download the program to MCU, and run it.
2. Can be found in PA7, EPWM waveform observed on pin PA8.
3. It can be observed that LED1 on the development board flips every 1 second.
3. EPWM overflow interrupt flips LED2.
================================================================================
注意事项：
LED引脚如下：
LED1       -> PC10
LED1       -> PC11

EPWM引脚如下：
EPWM_CH0_P    -> PA7
EPWM_CH0_P    -> PA8

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

The UART pins are as follows:
EPWM_CH0_P    -> PA7
EPWM_CH0_P    -> PA8
