After POR the device read dedicated EEPROM cells and transfers their content to into the control and configuration register
of the device. This way the device is configured and prepared for operation. The relation between EEPROM and register
address is shown here after (explanation of the bit meaning can be found in section 10.7.1 Internal registers:
