                             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，LED1每隔1s翻转一次。

Function descriptions:
This example demonstrates the forced output function of EPWM, resetting the 
normal output waveform of EPWM for 1 second, then configuring the forced output 
level for 1 second, and finally Restore normal output, 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引脚上观察到强制输出的EPWM波形。
3. 可观察到开发板上的LED1每隔1s翻转一次。

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

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

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

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