If the FIFO data output register driver is enabled (F_SETUP[f_mode] > 00), register 0x01 points to the head of the FIFO buffer,

while registers 0x02, 0x03, 0x04, 0x05, 0x06 return a value of zero when read directly.

The DR_STATUS registers, OUT_X_MSB, OUT_X_LSB, OUT_Y_MSB, OUT_Y_LSB, OUT_Z_MSB, and OUT_Z_LSB are

stored in the auto-incrementing address range of 0x00 to 0x06, allowing all of the acceleration data to be read in a single burst

read of 6 bytes starting at the OUT_X_MSB register. If the device is operating in hybrid mode and

M_CTRL_REG2[hyb_autoinc_mode] = 1, the magnetometer data can also be read out in the same axis and endian order by

executing a burst read of 12 bytes starting at register OUT_X_MSB.
