1、功能说明
    1、通过检测PC13 IO 高电平触发入侵中断。

2、使用环境

                  IAR EWARM 8.50.1 
    芯片支持：
        N32H730  
        N32H735   
        N32H735EC
        N32H760
        N32H762
        N32H765
        N32H765EC
        N32H785
        N32H785EC
        N32H787
    开发板支持：
        N32H787_EVB
        N32H787_HMI
        N32H787_EVB_PRO

3、使用说明
    
    系统配置:
        1、时钟源：LSE
        2、入侵检测IO：PC13
        3、串口配置：
                    - 串口为USART1（TX：PA9  RX：PA10）:
                    - 数据位：8
                    - 停止位：1
                    - 奇偶校验：无
                    - 波特率： 115200 
    使用方法：
        1、编译后烧录到评估板，上电后，PC13添加外部下拉，给PC13灌入高电平，串口输出RTC Tamper Interrupt。说明入侵检测发生了入侵中断
               
4、注意事项
    如果配置成上升沿或下降沿触发入侵，需要配置不滤波且在入侵引脚上外接上拉或下拉


1. Function description

    1. Tamper interrupt is triggered by detecting PC13 IO high level.

2. Development environment

    Software development environment: KEIL MDK-ARM V5.34

3. How to use

    System configuration:

        1. RTC Clock source: LSE
        2. Tamper detection IO: PC13
        3. Serial port configuration:
                            - Serial port: USART1 (TX: PA9 RX: PA10) :
                            - Data bit: 8
                            - Stop bit: 1
                            - Parity check: None
                            - Baud rate: 115200

    Instructions:
        1. After compiling, it is burned to the evaluation board. After powering on, add an external pull-down on PC13, then high level is artificially injected into PC13 and "RTC Tamper interrupt" is output through the serial port. 
        It indicates that the tamper interrupt is detected
        
4. Attention
    If a rising or falling edge is configured to trigger a tamper, disable filter and an external pull up or pull down is required on the tamper pin
