Operating Modes

The DPS310 supports 3 different modes of operation: Standby, Command, and Background mode.

• Standby Mode

- Default mode after power on or reset. No measurements are performed.

- All registers and compensation coefficients are accessible.

• Command Mode

- One temperature or pressure measurement is performed according to the selected precision.

- The sensor will return to Standby Mode when the measurement is finished, and the measurement result

will be available in the data registers.

• Background Mode

- Pressure and/or temperature measurements are performed continuously according to the selected

measurement precision and rate. The temperature measurement is performed immediately after the

pressure measurement.

- The FIFO can be used to store 32 measurement results and minimize the number of times the sensor must

be accessed to read out the results.

Note:

Operation mode and measurement type are set in the Sensor Operating Mode and Status

(MEAS_CFG) register.
