1
Data Nybble 1 is transmitted first.
2 If the configuration register settings have configured the ADXL180 for a range other than 50 g , 100 g, or 200 g, the other code (0011b) is sent. In these cases, the UD
bits can be used to indicate the actual range.
3
X indicates that the data is device dependent.
