                             Sample Description
================================================================================
功能描述：
该样例演示了EPWM的强制输出功能，复位EPWM正常输出波形1s，然后配置强制输出电平1s，最后
恢复正常输出。

Function descriptions:
This example demonstrates the forced output function of the Enhanced Pulse Width 
Modulation (EPWM). It resets the normal output waveform of EPWM for 1 second, 
then configures the forced output level for 1 second, and finally restores the 
normal output.

测试环境：
测试用板：DPM32M036_REV_A
MDK版本： 5.28

Test environment:
Test board: DPM32M036_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
