Register 0x05 (ACCD_Y_MSB)
The register contains the most-significant bits of the Y-channel acceleration readout value.
When reading out Y-channel acceleration values, data consistency is guaranteed if the
ACCD_Y_LSB is read out before the ACCD_Y_MSB and shadow_dis=’0’. In this case, after the
ACCD_Y_LSB has been read, the value in the ACCD_Y_MSB register is locked until the
ACCD_Y_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_Y_MSB at any time except
during power-up and in DEEP_SUSPEND mode.
