请问gaant_jx,当选择read-out protection后,是不是就不可以再用falsh 作为数据存储用,也就是说选择read-out protection后禁止再写FLASH. 还有当不选read-out protection时,st7也有很高的保密性,几乎可以认为是不可**的。 多谢!祝工作愉快!
以下是原始文档from st72321m9.pdf
Read-out protection, when selected, provides a protection against Program Memory content extraction and against write access to Flash memory. Even if no protection can be considered as totally unbreakable, the feature provides a very high level of protection for a general purpose microcontroller. |
