Since there are no register on the barometer chip you have to follow the given procedure to read

data after power up:

1. Issue Reset

2. Read PROM (128 bit of calibration words)

3. Initiate pressure (D1) conversion followed by Read ADC result (24 bit)

4. Initiate temperature (D2) conversion followed by Read ADC result (24 bit)

For detailed description of the commands and data processing refer to the datasheet.
