1、功能说明
    此例程展示了OTPC读写用户可用OTP空间

2、使用环境

    软件开发环境：KEIL MDK-ARM V5.34
                 IAR EWARM 8.50.1

    芯片支持：
        N32H785
        N32H785EC
        N32H787
		
3、使用说明

    系统配置
        1、时钟源：HSI+PLL
        2、系统时钟频率：
			M7 核：    600MHz
        3、端口配置：
        4、OTPC:
        OTPC读写用户可用OTP空间，可用空间：0x500 - 0x5ff
        

    使用方法：
        1、将78x的GPIO的LedBlink demo和当前CM4的工程程序分别编译后下载到开发板并复位运行。
        2、可观察串口输出信息，先判断地址是否可写，如果可写则写入并读出地址数据，不可写则读出地址数据

4、注意事项
    OTP是一次性编程，一个地址只能写一次，OTP有复杂的权限，操作其它地址时先检查是否有权限进行读写

2. Development environment

    Software development environment: KEIL MDK-ARM V5.34
                                      IAR EWARM 8.50.1

    Supported chips:
        N32H785
        N32H785EC
        N32H787

3. How to use

    System Configuration:
        1. Clock source: HSI+PLL
        2. System Clock frequency
		   M7 Core:     600MHz
        3.Port
        4.OTPC:
        Read Write OTP addr at 0x500 - 0x5ff
        
     Instructions:
        1. Compile the LedBlink demo for 78x's GPIO and the current CM4 project program respectively, 
           then download them to the development board and reset to run.
        2. Check the USART print information, if the addr can be Writeen, then Write the data and readout the data, if the addr can not be Written then just Readout the data

4. Attention
    OTP is One Time Programble, the address can only be Written One time
    The OTP has Complex Access Control , when Operate Other Address Please make sure the address can be Accessed
