1.9 Code Encryption (Super Lock)
Basically user code data will be programmed with raw data in Flash area. Although code data read
mode is protected with lock mode, its contents are vulnerable for several codes hooking method. We
provide the code encryption method to secure the user code data. The original user code will be
scrambled with user seed key value (private key). The scrambled data is programmed in flash area.
The fetched code during CPU operation will be decoded with the user key in configuration area.
