                             Sample Description
================================================================================
功能描述：
此样例演示TAMPER中断功能，TAMPER中断事件把数据备份寄存器的内容清除。

Function descriptions:
This example demonstrates the TAMPER interrupt function, where the TAMPER 
interrupt event clears the contents of the data backup register.
================================================================================
测试环境：
测试用板：PY32F410_STK
MDK版本： 5.28
IAR版本： 9.20
GCC版本：GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
Test board: PY32F410_STK
MDK Version: 5.28
IAR Version: 9.20
GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10
================================================================================
使用步骤：
1. 编译并下载程序到MCU；
2. 按下STK复位按键，LED灯亮起，表明数据备份寄存器成功写入特定的数据;
3. 将TAMPER引脚（PC13)接地，LED灯闪烁，表明产生了TAMPER入侵事件且数据备份寄存器
的内容被成功清除。

Example execution steps:
1. Compile and download the programme to the MCU;
2. Press the STK reset button and the LED lights up, indicating that the 
data backup register has been successfully written with specific data; and
3. Ground the TAMPER pin (PC13) and the LED blinks to indicate that a TAMPER 
intrusion event has been generated and the contents of the Data Backup Register 
have been successfully cleared.
