62 / 236 page  MCP19124/5 DS20005619A-page 62 2016 Microchip Technology Inc. 9.5 Calibration Word 5 The TANA<9:0> bits at memory location 2084h contain the ADC reading from the internal temperature sensor when the silicon temperature is at 28°C. This temperature can typically vary +2°C / -3°C. This 10 bit reading can be used to calculate the silicon die temperature. The temperature coefficient of the internal temperature sensor is typically 14.0mV/°C, +/-0.8mV/°C from -20°C to +125°C. See Section 25.0 “Internal Temperature Indicator Module” for more details. 9.6 Calibration Word 6 The FCAL<6:0> bits at memory location 2085h set the internal oscillator calibration. Firmware must read these values and copy into the OSCCAL Special Func- tion Register located in Bank 3 at 198h.
