POUT[7:0] This register contains the low part of the pressure output value.
The pressure output value is 24-bit data that contains the measured pressure. It is
composed of PRESS_OUT_H (2Ah) , PRESS_OUT_L (29h) and
PRESS_OUT_XL (28h) .
The value is expressed as 2’s complement.
The output pressure register PRESS_OUT is provided as the difference between the measured pressure and the content of the register RPDS (18h, 19h)*.
Please refer to
Section 3.5: Interpreting pressure readings for additional info.
