REF_P_H (17h)

Reference pressure (MSB part)

RPDS_L (18h)

Pressure offset (LSB data)

The pressure offset value is 16-bit data that can be used to implement one-point calibration

(OPC) after soldering. This value is composed of RPDS_H (19h) and RPDS_L (18h). The

value is expressed as 2’s complement.
