Data Ready Status
to the OUT_X, OUT_Y, and OUT_Z registers.
Table 10. DR_STATUS Register
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
previous data is overwritten. ZOW is cleared any time OUT_Z_MSB register is read.
YOW is set to 1 whenever new Y-axis acquisition is completed before the retrieval of the previous data. When this occurs the
previous data is overwritten. YOW is cleared any time OUT_Y_MSB register is read.
XOW is set to 1 whenever new X-axis acquisition is completed before the retrieval of the previous data. When this occurs the
previous data is overwritten. XOW is cleared any time OUT_X_MSB register is read.
ZYXDR signals that new acquisition for any of the enabled channels is available. ZYXDR is cleared when the high-bytes of the
data (OUT_X_MSB, OUT_Y_MSB, OUT_Z_MSB) of all the enabled channels are read.
ZDR is set to 1 whenever new Z-axis data acquisition is completed. ZDR is cleared any time OUT_Z_MSB register is read.
YDR is set to 1 whenever new Y-axis data acquisition is completed. YDR is cleared any time OUT_Y_MSB register is read.
XDR is set to 1 whenever new X-axis data acquisition is completed. XDR is cleared any time OUT_X_MSB register is read.
