DR_STATUS (0x00)
Data Ready Status
This read-only status register provides the acquisition status information on a per-sample basis, and reflects real-time updates
to the OUT_X, OUT_Y, and OUT_Z registers.
to the OUT_X, OUT_Y, and OUT_Z registers.
ZYXOW is set to 1 whenever new data is acquired before completing the retrieval of the previous set. This event occurs when
the content of at least one data register (i.e. OUT_X, OUT_Y, OUT_Z) has been overwritten. ZYXOW is cleared when the high-
bytes of the data (OUT_X_MSB, OUT_Y_MSB, OUT_Z_MSB) of all active channels are read.

ZOW is set to 1 whenever new Z-axis acquisition is completed before the retrieval of the previous data. When this occurs the
