Description:
The PRESS_OUT_XL register contains the lowest part of the pressure output value,
that is the difference between the measured pressure and the reference pressure
(REF_P registers).See AUTOZERO bit in CTRL_REG2.The full reference pressure
value is composed by PRESS_OUT_H/_L/_XL and is represented as 2’s
complement. Pressure Values exceeding the operating pressure Range (see Table 3)
are clipped.
Pressure output data: Pout(hPa) = PRESS_OUT / 4096
Example: P_OUT = 0x3ED000 LSB = 4116480 LSB = 4116480/4096 hPa= 1005 hPa
Default value is 0x2F800 = 760 hPa
