Register 0x06 (ACCD_Z_LSB)
The register contains the least-significant bits of the Z-channel acceleration readout value.
When reading out Z-channel acceleration values, data consistency is guaranteed if the
ACCD_Z_LSB is read out before the ACCD_Z_MSB and shadow_dis=’0’. In this case, after the
ACCD_Z_LSB has been read, the value in the ACCD_Z_MSB register is locked until the
ACCD_Z_MSB has been read. This condition is inherently fulfilled if a burst-mode read access
is performed. Acceleration data may be read from register ACCD_Z_LSB at any time except
during power-up and in DEEP_SUSPEND mode.
