                             Sample Description
================================================================================
功能描述：
该样例演示了EPWM的死区插入功能，PA7,PA8输出带死区EPWM波形。

Function descriptions:
This sample demonstrates the dead-time insertion function of EPWM. PA7 and PA8 
output EPWM waveforms with dead-time.

测试环境：
测试用板：DPM32M030_REV_A
MDK版本： 5.28

Test environment:
Test board: DPM32M030_REV_A
MDK Version: 5.28
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行。
2. 可在PA7,PA8引脚上观察到带死区的EPWM波形。

Example execution steps:
1. Compile and download the program to MCU, and run it.
2. The EPWM waveforms can be observed on the pins PA7 and PA8.
================================================================================
注意事项：
EPWM引脚如下：
EPWM_CH0_P    -> PA7
EPWM_CH0_P    -> PA8

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