6.9 Memory Protection
The device features memory protection for user access authority and write protection, including options to:
- Secure the whole memory map to prevent unauthorized access from JTAG port or BSL, by writing JTAG and BSL signatures using the JTAG port, SBW, the BSL, or in-system by the CPU.
- Enable write protection to prevent unwanted write operation to FRAM contents by setting the control bits in the System Configuration 0 register. For detailed information, see the SYS chapter in the MP430FR4xx and MP430FR2xx Family User's Guide.
