REF_P_L (15h)

Reference pressure LSB data (R)

REFL7

REFL6

REFL5

REFL4

REFL3

REFL2

REFL1

REFL0

REFL[7:0]

This register contains the low part of the reference pressure value. Default value: 00000000

The Reference pressure value is 16-bit data and it is composed of REF_P_H (16h) and REF_P_L (15h). The

value is expressed as 2’s complement.

The reference pressure value is stored and used when the AUTOZERO or AUTOREFP function is enabled.

Please refer to the INTERRUPT_CFG (0Bh) register description.

REF_P_H (16h)

Reference pressure MSB data (R)

REFL15

REFL14

REFL13

REFL12

REFL11

REFL10

REFL9

REFL8

REFL[15:8]

This register contains the high part of the reference pressure value. Default value: 00000000

9.13

RPDS_L (18h)

Pressure offset (LSB data)

RPDS7

RPDS6

RPDS5

RPDS4

RPDS3

RPDS2

RPDS1

RPDS0

RPDS[7:0]

This register contains the low part of the pressure offset value. Default value: 00000000

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.

9.14

RPDS_H (19h)

Pressure offset (MSB data)

RPDS15

RPDS14

RPDS13

RPDS12

RPDS11

RPDS10

RPDS9

RPDS8

RPDS[15:8]

This register contains the high part of the pressure offset value. Default value: 00000000

Refer to RPDS_L (18h).
