ZYXOW
X-, Y-, Z-axis data overwrite
• Asserted whenever new X-, Y-, and Z-axis data is acquired before completing the retrieval of the
previous set.
• Cleared after the high-bytes of the data of all channels (OUT_X_MSB, OUT_Y_MSB,
OUT_Z_MSB) are read.
0: No data overwrite has occurred
1: X, Y, and Z data overwrite occurred before the previous data was read
6
ZOW
Z-axis data overwrite
• Asserted whenever a new Z-axis acquisition is completed before the retrieval of the previous data.
When this occurs, the previous data is overwritten.
• Cleared anytime the OUT_Z_MSB (and respectively OUT_Y_MSB, OUT_X_MSB) register is
read.
0: No data overwrite has occurred
1: Z-axis data overwrite occurred before the previous data was read
