9.2 Device Information Area
The Device Information Area (DIA) is a dedicated region in the program memory space. The DIA contains the calibration data for the internal temperature indicator module, the Microchip Unique Identifier words, and the Fixed Voltage Reference voltage readings measured in mV.
The complete DIA table is shown below, followed by a description of each region and its functionality. The data is mapped from 2C0000h to 2C003Fh. These locations are read-only and cannot be erased or modified. The data is programmed into the device during manufacturing.
