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.
