(0: boot phase not running; 1: boot phase is running)

Interrupt active.

(0: no interrupt has been generated;

1: one or more interrupt events have been generated).

Differential pressure Low.

(0: no interrupt has been generated;

1: low differential pressure event has occurred).

Differential pressure High.

(0: no interrupt has been generated;

1: high differential pressure event has occurred).
