normal mode.
Accelerometer and gyroscope multiple reads (burst)
When only accelerometer is activated and the gyroscope is in power down, starting from
OUT_X_XL (28h - 29h) multiple reads can be performed. Once OUT_Z_XL (2Ch - 2Dh) is
read, the system automatically restarts from OUT_X_XL (28h - 29h) (see Figure 6).

When both accelerometer and gyroscope sensors are activated at the same ODR, starting
from OUT_X_G (18h - 19h) multiple reads can be performed. Once OUT_Z_XL (2Ch - 2Dh)
is read, the system automatically restarts from OUT_X_G (18h - 19h) (see Figure 7).
