The MSP432P4xx family includes a complete peripheral driver library (DriverLib) fully integrated into the ROM memory. Developers can leverage the ROM DriverLib for multiple benefits including access to highly robust and tested APIs, single-cycle ROM execution speed at lower power consumption, and freeing up memory space for additional application code. Developers can gain access to ROM APIs by adding DriverLib header file to their projects and linking to a prebuilt library. However, to step into and view the ROM code and disassembly, a few extra steps are needed. This application report details the steps to start a new project with ROM debugging or to add ROM debugging capability to an existing project and how to debug with ROM in the Code Composer Studio™ IDE (CCS).
