Configuration and Calibration Parameters

The TLE4998C8(D) has several configurable parameters which are stored in the EEPROM. These parameters

affect the internal data processing and compensation and the output protocol. This chapter gives an overview of

the parameters. A detailed description of all the parameters and the programming procedure is given in the
