ADVANCE INFORMATION
The temperature sensor provides a voltage output that changes linearly with device temperature. The temperature sensor output is internally connected to one of ADC input channels to enable a temperature-to-digital conversion.
A unit-specific single-point calibration value for the temperature sensor is provided in the factory constants memory region. This calibration value represents the ADC conversion result (in ADC code format) corresponding to the temperature sensor being measured in 12-bit mode with the 1.4-V internal VREF at the factory trim temperature (TSTRIM).
The ADC and VREF configuration for the above measurement is as the following: RES=0 (12-bit mode), VRSEL=0h (VDD), BUFCONFIG=1h (1.4V VREF), ADC tSample=10µs. This calibration value can be used with the temperature sensor temperature coefficient (TSc) to estimate the device temperature.
See the temperature sensor section of the MSPM0 G-Series 80MHz Microcontrollers Technical Reference Manual for guidance on estimating the device temperature with the factory trim value.
