PRESS_OUT_XL (28h)

Either pressure output or AH/Qvar output value LSB data (read only)

POUT6

POUT5

POUT4

POUT3

POUT2

POUT1

POUT0

POUT[7:0]

This register contains the low part of the pressure or AH/Qvar output value.

The pressure output value is a 24-bit data that contains the measured pressure. It is composed of

PRESS_OUT_H (2Ah), PRESS_OUT_L (29h), and PRESS_OUT_XL (28h). The value is expressed as two's

complement.

The output pressure register PRESS_OUT is provided as the difference between the measured pressure and the

content of the register RPDS (18h, 19h).

This register contains the pressure value and the resolution is: 1 LSB = 1/4096 hPa (when FS_MODE = 0),

otherwise 1 LSB = 1/2048 hPa (when FS_MODE = 1), refer to Section 5.5 Interpreting pressure readings for

additional information.

PRESS_OUT_L (29h)

Either pressure output or AH/Qvar output value middle data (read only)

POUT15

POUT14

POUT13

POUT12

POUT11

POUT10

POUT9

POUT8

POUT[15:8]

This register contains the mid part of the pressure or AH/Qvar output value.

Refer to PRESS_OUT_XL (28h)

10.22

PRESS_OUT_H (2Ah)

Either pressure output or AH/Qvar output value MSB data (read only)

POUT23

POUT22

POUT21

POUT20

POUT19

POUT18

POUT17

POUT16

POUT[23:16]

This register contains the high part of the pressure or AH/Qvar output value.

Refer to PRESS_OUT_XL (28h)

10.23

TEMP_OUT_L (2Bh)

Temperature output value LSB data (read only)

TOUT7

TOUT6

TOUT5

TOUT4

TOUT3

TOUT2

TOUT1

TOUT0

TOUT[7:0]

This register contains the low part of the temperature output value.

The temperature output value is 16-bit data that contains the measured temperature. It is composed of

TEMP_OUT_H (2Ch), and TEMP_OUT_L (2Bh). The value is expressed as two's complement.

This register contains the temperature value and the resolution is: 1LSB = 0.01 °C.
