Abstract:

In this paper we study the protection mechanisms and security operations of XS128 Flash memory. By introducing the configuration regions in XS128 Flash memory, we elaborate P-FLASH/D-FLASH Protection Mechanisms and protection register FPROT/DFPROT. Besides, we put forward encryption/decryption methods to guarantee the security of MCU.
