REFL[7:0]
This register contains the low part of the reference pressure value.
The Reference pressure value is a 24-bit data and it is composed of Section 10.11:
"REF_P_H_17h", Section 10.10: "REF_P_L_16h" and Section 10.9: "REF_P_XL (15h)".
The value is expressed as 2’s complement.
The reference pressure value is used when AUTOZERO or AUTORIFP function is
enabled(refer to the Section 10.7: "CTRL_REG3 (12h)" register) and for the Autozero
function (refer to the Section 10.1: "INTERRUPT_CFG (0Bh)" register).
