Register 0x3F (FIFO_DATA)
FIFO data readout register. The format of the LSB and MSB components corresponds to that of
the acceleration data readout registers. The new data flag is preserved. Read burst access may
be used since the address counter will not increment when the read burst is started at the
address of FIFO_DATA. The entire frame is discarded when a fame is only partially read out.

fifo_data_output_register<7:0>:
FIFO data readout; data format depends on the setting of
register fifo_data_select<1:0>:
if X+Y+Z data are selected, the data of frame n is reading out in the order of
X-lsb(n), X-msb(n), Y-lsb(n), Y-msb(n), Z-lsb(n), Z-msb(n);
if X-only is selected, the data of frame n and n+1 are reading out in the order
of X-lsb(n), X-msb(n), X-lsb(n+1), X-msb(n+1); the Y-only and Z-only modes
behave analogously
