PD1, PD0 bit allows to turn on the turn the device out of power-down mode. The device is in
power-down mode when PD1, PD0= “00” (default value after boot). The device is in normal
mode when either PD1 or PD0 is set to 1.
DF1, DF0 bit allows to select the data rate at which acceleration samples are produced. The
default value is 00 which corresponds to a data-rate of 40Hz. By changing the content of DF1,
DF0 to “01”, “10” and “11” the selected data-rate will be set respectively equal to 160Hz, 640Hz
and to 2560Hz.
