6.10.4 Device Security
The MSP432P401xx MCUs offer the following two types of device security for the user application code
programmed on to the device.
•
JTAG and SWD Lock
•
IP Protection
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. Up to four IP-protected zones with configurable start address and size are supported. The
security configurations of the device are done using the flash boot-override mailbox.
Also the SYSCTL 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
System Controller (SYSCTL)
chapter in the
Microcontrollers Technical Reference Manual
