Latch interrupt request to the INT_SOURCE (25h) register. Default value: 0.
(0: interrupt request not latched; 1: interrupt request latched)
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)
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)

Interrupt active.
(0: no interrupt has been generated;
1: one or more interrupt events have been generated).
PL
Differential pressure Low.
(0: no interrupt has been generated;
1: Low differential pressure event has occurred).
PH
