Procedure for single acquisition (low power consumption)
If the LPS001WP output data rate requested is lower than 7 Hz, a dedicated procedure to
reduce the power consumption can be implemented.
LPS001WP is in power down, then it is woken up for the acquisition and again put in power
down. This procedure reduces the power consumption.
