* XCLR is to reset the AD converter (active low). XCLR should be set to high only during AD
conversion phase(reading D1,D2), at all other states, such as reading calibration factors, this pin
should be kept low.
* The quality of the MCLK signal can significantly influence the current consumption of the
pressure module. To obtain minimum current, remember to supply good quality MCLK signal
