                                样例使用说明
                             Sample Description
================================================================================
功能描述：
该样例演示了EPWM的软件触发紧急停止功能，复位后EPWM正常输出波形1s，软件触发急停1s，最后
恢复正常输出，LED1每隔1s翻转一次。

Function descriptions:
This example demonstrates the software triggered emergency stop function of EPWM. 
After resetting, EPWM outputs a normal waveform for 1 second, the software 
triggered emergency stop 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, Observe the EPWM waveform 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
