Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.

5. Control Registers
The control registers allow the user to set the threshold values for various event detections, configure the interrupt setting,
and enable/disable the data compensation. It is recommended for the user to set these registers to the desired values before
performing the conversions or any other command-based operations. The following is a table of all the control registers.
The registers from 0x00 to 0x0A are designed for the user to setup the parameters (offset and thresholds) for pressure (or
altitude) and temperature event detections. The registers from 0x0B to 0x0D are used for interrupt controls. The register of
0x0E is dedicated for switching on/off the sensor output compensation function inside the device.
