RPDS[7:0]
This register contains the low part of the pressure offset value.
If, after the soldering of the component, a residual offset is still present, it can be removed
with a one-point calibration.
After the soldering, the measured offset can be stored in the Section 10.13:
"RPDS_H_19h" and Section 10.12: "RPDS_L_18h" registers and automatically subtracted
from the pressure output registers: the output pressure register PRESS_OUT (28h, 29h
and 2Ah) is provided as the difference between the measured pressure and the content of
the register 256*RPDS (18h, 19h)*.
*DIFF_EN = '0', AUTOZERO = '0', AUTORIFP = '0'

Notes:
(1)These bits must be set to ‘0’ for proper operation of the device.
(2)The content of this bit must not be modified for proper operation of the device
LC_EN (1)
Low current mode enable. Default 0.
0: Normal mode (low-noise mode); 1: Low-current mode).

LC_EN
Notes:
(1)The LC_EN bit must be changed only with the device in power down and not during operation. Once LC_EN bit
is configured, it affects both One-shot mode and Continuous mode.
