The dual code security module (DCSM) is a security feature incorporated in this device and prevents access and visibility to on-chip secure memories (and other secure resources) by unauthorized persons. The DCSM also prevents duplication and reverse-engineering of proprietary code. The term “secure” means that access to on-chip secure memories and resources is blocked. The term “unsecure” means that access is allowed; that is, the contents of the memory can be read by any means (for example, through a debugging tool such as Code Composer Studio™ IDE.
The CSM has dual-zone security, Zone1 (Z1) and Zone2 (Z2).
