DocID023722 Rev 5

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.

7.1

REF_P_XL

Reference pressure (LSB data)

Address:

08h (R/W)

Reset:

00h

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).
