Read operation to REST_MODE_CONFIG indicates which mode the sensor is in. Write operation into this register

will force the sensor into rest modes (Rest 1, 2 or 3). Write the value 0x40 into 0x45 register to force sensor into

Rest 1, 0x80 to Rest 2 or 0xC0 to Rest 3. To get out of any forced rest mode, write 0x00 into this register to set

back to normal mode.
