Data Type 

The 4-bit Data Type field determines the type of data of the specific sensor. 

Factory Calibrate 

The Factory Calibrate bit is used during factory calibration. If set, factory calibration is 
performed on the raw sensor reading PRIOR to user scaling. 

Writeable 

The writeable bit is cleared, indicating that the sensor values may not be overwritten. 

Smart Sensor 

This bit is cleared.
