[2] LIR: Latch Interrupt request into INT_SOURCE register. Default value: 0.

(0: interrupt request not latched; 1: interrupt request latched)

[1] PL_E: Enable interrupt generation on differential pressure low event. Default value: 0.

(0: disable interrupt request;

1: enable interrupt request on measured differential pressure value lower than preset threshold)

[0] PH_E: Enable interrupt generation on differential pressure high event. Default value: 0

(0: disable interrupt request;

1:enable interrupt request on measured differential pressure value higher than preset

threshold)
