THS[7:0] This register contains the low part of threshold value for pressure interrupt generation.
The threshold value for pressure interrupt generation is a 16-bit register composed of
THS_P_H (31h) and THS_P_L (30h). The value is expressed as unsigned number: Interrupt
threshold(hPA) = (THS_P)/16.

The pressure offset value is a 16-bit data that can be used to implement One-Point
Calibration (OPC) after soldering, This value is composed of RPDS_H (3Ah) and RPDS_L
(39h). The value is expressed as 2’s complement.
