The power consumption of the ILPS28QSW mainly depends on the selected ODR (output data rate) and on
the selected resolution. The user can select the desired ODR and the oversampling frequency for pressure
measurements in the CTRL_REG1 (10h) register. The ODR[3:0] bits are dedicated to the ODR selection, while
the AVG[2:0] bits are used to configure the resolution.
