REF_P_XL (15h)

Reference pressure (LSB data)

Address:

15h (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

of REF_P_XL (15h), REF_P_L (16h), RPDS_L (18h) and is represented as 2’s

complement. The reference pressure value can also be used to detect a measured

pressure beyond programmed limits (see CTRL_REG3 (12h)), and for Autozero

function (see RESET_AZ bit, at INTERRUPT_CFG (0Bh)).

REF_P_L (16h)

Reference pressure (middle part)

Address:

16h (R/W)

Reset:

00h

Description:

The REF_P_L register contains the middle part of the reference pressure value that is

sum to the sensor output pressure. (See REF_P_XL (15h) description).

REF_P_H (17h)

Reference pressure (MSB data)

Address:

17h (R/W)

Reset:

00h

Description:

The REF_P_H register contains the highest part of the reference pressure value that

is sum to the sensor output pressure. (See REF_P_XL (15h) description).
