ACCELERATION DATA CODING
Table 12. DAT Data Bit Options
DAT

The sensor data coding is dependent on the configuration
register bit settings. Either 8-bit or 10-bit sensor data can be
transmitted. This 8-bit or 10-bit data range is either full range
or reduced range. Whether the data range is full or reduced
depends on the setting of the state vector disable and auto-zero
enable configuration register bits. For more information, see
Table 13.

SVD is the state vector disable configuration bit.
AZE is the auto-zero enable configuration bit.
A configuration error is reported if Phase 2 Mode 0 is selected with the state
vector disabled (SVD = 1). The ADXL180 transmits a configuration error code
during run time and no sensor data is transmitted.
