6.3 ADC67

ADC Module

Category

Software in ROM

Function

Invalid ADC12 temperature sensor calibration data

Description

The ADC12 reference temperature sensor calibration data stored in the TLV data structure (0x1A1A - 0x1A25) can be incorrect.
As a result the temperature measurement when using these data can be wrong.

Workaround

Record the calibration data by taking ADC measurements of the temperature sensor at 30C and 85C for the required reference voltage. The calibration data in the TLV section (0x1A1A - 0x1A25) can't be overwritten but the new calibration data can be stored in user FRAM or info memory for further temperature calculations.
