Datasheet
In a read cycle, the I2C master writes the device ID (R/W#=0) and register address to be read.
The master issues a RESTART condition and then writes the device ID with the R/W# flag set
to ‘1’. The device shifts out the contents of the register address.

The I2C master may write or read consecutive register addresses by writing or reading
additional bytes after the first access. The device will internally increment the register address.
If an I2C burst read operation reads past register address 0x12 the internal address
pointer “wraps” to address 0x03 and the contents of the TILT: Status Register are
returned. This allows application software to burst read the contents of the six extended
registers and the relevant device state registers in a single I2C cycle.
