MSP Code Protection Features

MSP microcontrollers (MCUs) offer a number of features to help control code accessibility in the device, to add different layers of code access management and protection strategies. These include features that can lock or password protect the JTAG/SBW access, IP Encapsulation (IPE) to isolate sensitive code with different permissions than the rest of the program, and bootloader (BSL) access features for field firmware updates. This application report details some of the features available in different MSP device families and considerations that can be taken to add additional layers of protection to the device.
