* 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
