9.1.3 Device Information Area (DIA)
The Device Information Area (DIA) is a dedicated region in the Program Flash Memory. The data is mapped from address 8100h to 811Fh. These locations are read-only and cannot be erased or modified. The DIA contains the Microchip Unique Identifier words, Temperature Indicator range data, and the Fixed Voltage Reference (FVR) voltage readings in millivolts (mV). The DIA Table holds the DIA information for the PIC16F180 family of microcontrollers.
