5.12.3 Analog-to-Digital Conversion Data of the Temperature Sensor
The purpose of the temperature indicator module is to provide a temperature-dependent voltage that can be measured by an analog module. The “Temperature Indicator Module” chapter explains the operation of the Temperature Indicator module and defines terms such as the low range and high range settings of the sensor. The DIA table contains the internal ADC measurement values of the temperature sensor for low and high range at fixed points of reference. The values are measured during test and are unique to each device. The right-justified ADC readings are stored in the DIA memory region. The calibration data can be used to plot the approximate sensor output voltage, VTSENSE vs. Temperature curve.
- TSLR: Address 8112h to 8114h store the measurements for the low range setting of the temperature sensor at VDD = 3V.
- TSHR: Address 8115h to 8117h store the measurements for the high range setting of the temperature sensor at VDD = 3V.
The stored measurements are made by the device ADC using the internal VREF = 2.048V.
