7.1.1.2.1 Data Type
The 4-bit Data Type field determines the type of data of the specific sensor.
7.1.1.2.2 Factory Calibrate
No Factory calibration is used on the digital pulse inputs.
7.1.1.2.3 Writeable
The writeable bit is set, indicating that the sensor values may be overwritten. This allows values to
be preset, such as setting a counter value to 0.
