RPDS_L (18h)

Pressure offset (LSB data)

If, after the soldering of the component, a residual offset is still present, it can be removed

with a one-point calibration.

After soldering, the measured offset can be stored in the RPDS_H (19h) and 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'

This register contains the high part of the pressure offset value.

Refer to RPDS_L (18h).

0(1)

LC_EN

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)

1. The LC_EN bit must be changed only with the device in power down and not during operation. Once the

LC_EN bit is configured, it affects both One-shot mode and Continuous mode.

Low-current mode enable. Default: 0

(0: normal mode (low-noise mode); 1: low-current mode).
