RPDS_L (18h)

Pressure offset (LSB)

Address:

18h (R/W)

Reset:

00h

Description:

This register contains the low part of the pressure offset value after soldering, for

differential pressure computing. The complete value is given by RPDS_H (19h) and

RPDS_L (18h) and is expressed as signed 2’s complement value.

[7:0] RPDS7-0: Pressure offset for one-point calibration after soldering

RPDS_H (19h)

Pressure offset (MSB)

Address:

19h (R/W)

Reset:

00h

Description:

This register contains the high part of the pressure offset value after soldering (see

description RPDS_L (18h))

[15:8] RPDS15-8: Pressure offset for one-point calibration after soldering.
