9.1.4.1 DIA and DCI Access

The DIA and DCI data are read-only and cannot be erased or modified. See “NVMREG Access to DIA, DCI, User ID, DEV/REV ID, and Configuration Words” section in the “NVM - Nonvolatile Memory Control” chapter for more information on accessing these memory locations.

Development tools, such as device programmers and debuggers, may be used to read the DIA and DCI regions, similar to the Device ID and Revision ID.
