9.3 Device Configuration Information

The Device Configuration Information (DCI) is a dedicated region in the program memory mapped from 3C0000h to 3C0009h. The data stored in these location is read-only and cannot be erased. Refer to the table below for the complete DCI table address and description. The DCI holds information about the device, which is useful for programming and Bootloader applications.

The erase size is the minimum erasable unit in the PFM, expressed as rows. The total device Flash memory capacity is (Erase size * Number of user-erasable pages).
