5.12 Device Information Area

The Device Information Area (DIA) is a dedicated region in the program memory space; it is a new feature in the PIC16(L)F184XX family of devices. The DIA contains the calibration data for the internal temperature indicator module, stores 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 8100h to 811Fh in the PIC16(L)F184XX family. These locations are read-only and cannot be erased or modified. The data is programmed into the device during manufacturing.
