11.5 NVM Temperature Log Row

The NVM Temperature Log Row contains calibration data that are determined and written during production test. These calibration values are required for calculating the temperature from measuring the temperature sensor in the Supply Controller (SUPC) by the ADC.

The NVM Temperature Log Row can be read at address 0x00806030.

The NVM Temperature Log Row can not be written.
