Table 29.
BDU bit is used to inhibit output registers update between the reading of upper and lower
register parts. In default mode (BDU = ‘0’) the lower and upper register parts are updated
continuously. If it is not sure to read faster than output data rate, it is recommended to set
BDU bit to ‘1’. In this way, after the reading of the lower (upper) register part, the content of
that output registers is not updated until the upper (lower) part is read too.
This feature avoids reading LSB and MSB related to different samples.

Table 31.
TurnOn bits are used for turning on the sleep to wake function.
Table 32.
Setting TurnOn[1:0] bits to 11 the “sleep to wake” function is enabled. When an interrupt
event occurs the device is turned to normal mode increasing the ODR to the value defined in
