The MSP432P4x1xT MCUs offer the following two types of device security for the user application code programmed on to the device.
JTAG and SWD lock as the name indicates locks the JTAG and SWD interface of the device. IP protection is useful for protection of customer software IP, for example, in multiple-vendor development scenarios. It is possible to have up to four IP protected zones with configurable start address and size. The security configurations of the device are set using the flash boot-override mailbox.
The SYSCTL_A module provides infrastructure for encrypted in-field updates to the application code on devices that are JTAG and SWD locked or have defined IP protection zones. For complete details of the device security features, see the SYSCTL_A chapter in the MSP432P4xx SimpleLink™ Microcontrollers Technical Reference Manual.
