When the ODR bits are set to 0000, the device is in power-down mode. When the device is in power-down

mode, almost all internal blocks of the device are switched off to minimize power consumption. The digital

interface is still active to allow communication with the device. The content of the configuration registers is

preserved and output data registers are not updated, therefore keeping the last data sampled in memory before

going into power-down mode.

If the ONESHOT bit in CTRL_REG2 (11h) is set to 1, one-shot mode is triggered and a new acquisition starts

when it is required. Enabling this mode is possible only if the device was previously in power-down mode (ODR

bits set to 0000). Once the acquisition is completed and the output registers updated, the device automatically

enters in power-down mode. The ONESHOT bit self-clears itself.

When the ODR bits are set to a value different than 0000, the device is in continuous mode and automatically

acquires a set of data (pressure and temperature) at the frequency selected through the ODR[3:0] bits.
