                             Sample Description
================================================================================
功能描述:
此样例配置系统时钟为HSI并通过MCOPA07引脚输出。

Function descriptions:
This example configures the system clock as HSI and outputs it through the 
MCO (PA07) pin.
================================================================================
测试环境:
测试用板PY32F002B_STK
MDK版本 5.28
IAR版本 9.20

Test environment:
Test board: PY32F002B_STK
MDK Version: 5.28
IAR Version: 9.20
================================================================================
使用步骤:
1. 编译下载程序到MCU并运行
2. 用示波器监测PA07引脚上的频率观察是否和配置的HSI频率一致。

Example execution steps:
1.Compile and download the program to MCU and run it;
2.Use an oscilloscope to monitor the frequency on the PA07 pin and observe if 
it matches the configured HSI frequency.
