 Module function: the module provides a bare flash area and a special read-write interface for customers to store important information, and the information will not be lost after burning the firmware (burning the firmware without this function cannot be guaranteed not to be lost). Provide a storage and read interface, not a delete interface.

 #### SecureData - 安全数据区
 
 模块功能：模组提供一块裸flash区域及专门的读写接口供客户存贮重要信息，且信息在烧录固件后不丢失(烧录不包含此功能的固件无法保证不丢失)。提供一个存储和读取接口，不提供删除接口。
