Table 12. STATUS Description
ZYXOW is set whenever a new acceleration data is produced before completing the retrieval of the previous set. This event
occurs when the content of at least one acceleration data register (i.e., OUT_X, OUT_Y , OUT_Z) has been overwritten. ZYXOW
is cleared when the high-bytes of the acceleration data (OUT_X_MSB, OUT_Y_MSB, OUT_Z_MSB) of all the active channels are
read.
ZOW is set whenever a new acceleration sample related to the Z-axis is generated before the retrieval of the previous sample.
When this occurs the previous sample is overwritten. ZOW is cleared anytime OUT_Z_MSB register is read.
YOW is set whenever a new acceleration sample related to the Y-axis is generated before the retrieval of the previous sample.
When this occurs the previous sample is overwritten. YOW is cleared anytime OUT_Y_MSB register is read.
XOW is set whenever a new acceleration sample related to the X-axis is generated before the retrieval of the previous sample.
When this occurs the previous sample is overwritten. XOW is cleared anytime OUT_X_MSB register is read.
ZYXDR signals that a new sample for any of the enabled channels is available. ZYXDR is cleared when the high-bytes of the
acceleration data (OUT_X_MSB, OUT_Y_MSB, OUT_Z_MSB) of all the enabled channels are read.
ZDR is set whenever a new acceleration sample related to the Z-axis is generated. ZDR is cleared anytime OUT_Z_MSB register
is read.
YDR is set whenever a new acceleration sample related to the Y-axis is generated. YDR is cleared anytime OUT_Y_MSB register
is read.
XDR is set whenever a new acceleration sample related to the X-axis is generated. XDR is cleared anytime OUT_X_MSB register
is read.
