Register description
LPS25H
The device contains a set of registers which are used to control its behavior and to retrieve
pressure and temperature data. The register address, made up of 7 bits, is used to identify
them and to read/write the data through the serial interface.

Description:
The REF_P_XL register contains the lowest part of the reference pressure value that
is sum to the sensor output pressure. The full reference pressure value is composed
by REF_P_XL, REF_P_H & REF_P_L and is represented as 2’s complement. The
reference pressure value can also be used to detect a measured pressure beyond
programmed limits (see INT_CFD at 23h), and for Autozero function (see RESET_AZ
bit, at 20h).
