The power consumption of the ILPS22QS 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.
